Light
Where you position your indoor garden will depend on the light requirements the plants have. Plants grown indoors will never have access to the same direct bright sunlight they could get outdoors; even sunlight streaming through a window is less intense than it is outdoors. You may need grow lights to help create the right conditions for major sun-loving plants indoors or if you don't have any natural light in an apartment. Conversely, if you have true shade-loving plants, keeping them away from windows will be important.

Soil
If you aren't opting for a hydroponic setup or collecting air plants, your indoor garden will generally be best grown in a loose, well-drained potting mix. The mix can be tailored depending on what you grow, but it is often composed of peat moss, vermiculite, and perlite. This combination absorbs moisture quickly and doesn't become easily compacted. However, it will dry out quickly, so it won't work for moisture-loving plants, like ferns.

Water
Of course, every plant grown indoors will have differing requirements in terms of watering. However, one of the biggest common problems for indoor gardens is overwatering. Many indoor plants die as a result of root rot.

Always research what the plant species you are growing needs. It's also a good idea to water your plants with distilled room temperature water. Cold tap water can sometimes shock your plants.

Fertilizer
Ensuring your indoor garden plants receive enough nutrients is important for long term success. Although some potting soils have nutrient enhancements, the plants will use them up after a couple of months. Slow-release fertilizers are popular as they can last several months before another application is required.

Temperature and Humidity
Being able to control the temperature and humidity in an indoor environment is one of the key benefits of indoor gardening. The ideal humidity levels for many indoor plants ranges from around 40 to 60 percent humidity.

If you have moisture-loving plants that need high humidity or your living space is particularly dry during the winter months when the heating is on, you could invest in a humidifier or set up the garden in your bathroom. You can also use indoor greenhouses or terrariums.

Repotting
Repotting your indoor garden plants annually, or when they are becoming root bound, is vital for long term growth and health. Make sure the pot is big enough for future growth.

Plants for Indoor Gardening
Certain plants are known for being well-suited to being grown indoors. These include:

Veggies. Some veggies grow particularly well indoors. These include carrots, hot peppers, lettuce, and tomatoes.
Herbs. Basil, chives, mint, parsley, and thyme are just a few herbs that do well in a sunny position indoors.
Low-Light plants. If you are looking to create a low-maintenance tropical jungle in a shady area in your home, opt for low-light species like spider plants, snake plants, and certain ferns.
Humidity-loving plants. If you want plants for a terrarium or to grow in a bathroom, consider things like begonias, ferns, and peace lilies.

Chip on Board (COB)
Chip on board (COB led grow lights) feature a number of tiny LEDs placed close together on a single chip, resulting in a single powerful point of light. While the center point of the area they cover receives optimal lighting, they don’t offer the same level of widespread, equal coverage as spread-style LEDs.

Since they’re so powerful, COB lights often emit more heat than other types of LEDs and may require the use of fans to cool down the area. They use full-spectrum white LED diodes and provide deeper canopy penetration than spread-style LEDs.

Traditional
Traditional LED grow lamps are usually compact, making them a good choice for small spaces. They use LEDs that provide medium power and typically feature multicolored LEDs that cover the full spectrum of color frequencies, unlike white LEDs. This gives their light a colorful appearance that indoor growers might or might not like.

What to Consider When Choosing the Best LED Grow Lights
The following sections detail some of the most important qualities to keep in mind when shopping for the best LED grow lights for your needs.

Light Spectrum
Natural sunlight features all the colors on the electromagnetic spectrum. Some LED lights can reproduce only certain color frequencies, while full-spectrum white LED lights produce all the hues necessary for every stage of the growing process.

Blue light helps plants grow in the earliest stages of their lives. It’s the first color plants can absorb in their vegetative state.
Purple light is also used in the vegetative state; however, it’s not as effective for photosynthesis as blue light.
Red light helps in the latter stages of growing and is essential for buds to flower.
White light encompasses all the colors of the spectrum. Used alone, it can be effective for every developmental stage.
Power
It’s a bit difficult to compare LED grow lights because manufacturers use a variety of metrics to measure the power of their lights and the amount of light they emit. The brightness of LED lights is measured in lumens. Seedlings require approximately 2,000 lumens per square foot to thrive, while flowering plants may need as much as 10,000 lumens.

While lumens measure visible light, biologists often use photosynthetic photon flux (PPF) or photosynthetic photon flux density (PPFD) to measure light intensity in terms of the light that indoor plants will actually absorb. PPF is measured in μmol/second (or micromoles per second), which is the number of photons of light emitted every second. PPFD is also measured in micromole/m2/s and measures the density of light distributed per square meter per second. The higher the PPF and PPFD, the more effective the light should be.

Heat Output
One of the risks when using a grow light is that the heat emitted by the bulbs can damage your plants. However, LED lights give off very little heat relative to the amount of light they produce. But they do produce some heat, so many models are equipped with built-in cooling systems to ensure proper temperature regulation.

Some LED lights have aluminum heat sinks, and others come equipped with fans. A unit with a fan might be loud, so factor noise level into your choice when selecting a grow light.

Coverage and Wattage
To choose the right plant grow light, you’ll first need to establish how much coverage you need. To do this, group the plants together and measure the square footage they take up. Most grow lights will clearly list the coverage they provide.

To establish how much electricity a light uses, look for its “actual power draw” or “actual power consumption.” This is measured in watts and gives a good indication of the light’s power. Bulb wattage is not a good indicator because LEDs are designed to be energy efficient.

Connectivity
Many LED grow lights are designed to link to other units to cover larger areas, which is typically referred to as “daisy-chain connectivity.” Products with this capability simply plug into each other and then plug into one outlet, which minimizes the number of cords required for setup.

Types of LED Grow Lights
As we mentioned earlier, LEDs are some of the most flexible, tailorable options out there when it comes to grow lights for your grow room. In terms of power, the wattages you’ll typically find LED lights in ranges from 25w to 1000w led grow light. This is thanks in large part to their chip-based makeup.

There’s also a wide variety of LED grow light styles. You can find traditional panel style LEDs, spread lights, COB led grow lights and board led grow lights.

Traditional panel LED lights are the most compact LEDs. They’re usually made up of small-to-medium wattage diodes that are equipped with 1 to 2 lenses each. This helps spread light out and focus it down onto your plants.
Spread style LED lights tend to be a larger option. They’re made up of a lot of tiny chips that are spread out over a wide area. This design allows spread style LEDs to give off all the lumens of light your plants need to thrive.
COB grow lights are made up of a small amount of chip on board bulbs — in some cases, they’re made with just one of these. COB lights utilize a bunch of tiny chips in one diode in order to create a super-powered diode. A few of these super high strength diodes will give you large amounts of power, light, and intensity for you grow room.

What Are the Advantages of LED Grow Lights?
If it’s not already clear, the biggest plus of using LED grow lights is probably the amount of flexibility they offer.

LEDs Can Out-Intensify HIDs: Because LEDs can target multiple wavelengths and strengths, they can give your plants great light intensity. The lens makeup and chip strength of an LED means you have plenty of different options for your grow room needs — whereas HIDs are pretty basic and target only specific wavelengths.
LEDs Give Your Plants a More Dialed-In Spectrum: HIDs will give you some wavelengths that your plants will unfortunately waste. LEDs, however, provide more diverse wavelengths. They can also be programmed to offer other wavelengths like IR and UV.
LEDs Run Cooler Than HIDs: Though some heat is beneficial to plants, too much heat can cause problems in the grow environment. LEDs keep temperatures lower than HIDs, which also means you’ll save on cooling equipment that you’d need to get rid of excess heat from HIDs.
LEDs make awesome grow lights for your plants, but they still have their share of challenges.

LEDs Cost More Than HIDs: Though you’ll save in the long run, LEDs are usually pretty expensive upfront compared to HIDs. Typically, you’re looking at spending around twice as much on an LED grow light than you would on an HID.
Finding the Right LED Can Be Tricky: With so many types of LEDs and chip combinations, it can be difficult figuring out which LED grow light is best for your plants.

HIDs, or high-intensity discharge grow lights, are powered by gas. There are two main types of HID grow lights: high-pressure sodium lights (HPS) and metal halide lights (MH).

HPS grow lights hold their chemicals (like sodium, mercury, and xenon) in a narrow arc tube containing a lot of high pressure. The arc tube is typically made out of aluminum oxide ceramic, making it resistant to corrosion from all the sodium.
MH grow lights use bulbs that typically have a quartz arc tube which contains metal halide, like the name suggests.
With these grow bulbs, light is created when a ballast is heated and an electric arc is sent between two electrodes within the arc tube, which is filled with the bulb's gases and metal salts.
So why does this all matter with regard to your grow room and plants?

Why Grow with HID Lights?

HPS and MH grow lights work in slightly different ways and give off different wavelengths, since the grow bulbs contain different gases and chemicals.

HPS Light Spectrum: HPS bulbs provide a lot of yellow, red, and far-red in their spectrum — this makes them ideal for flowering plants.
MH Light Spectrum: MH grow bulbs give off a cool white light when heated, which gives off a good amount of blue wavelengths in its spectrum. This is why MHs make a better grow light option than HPS lights when it comes to helping plants thrive in the vegetative phase.
HIDs Mimic the Sun: Growing indoors, your plants won't be exposed to natural sunlight. That said, HID grow lights mimic the sun closely, which means your plants will get light intensity that's close to what they'd receive if they were growing outside.
HIDs Give Off Heat Energy: Some warmth is actually really good for your plants. HID grow lights generate heat, and this heat is able to provide more energy for your plants, which stimulates growth.

Types of HID Grow Lights
Although they may not be as customizable as LED lights, you do have a few options when it comes to choosing HID grow lights.

HID Grow Light Wattages: Aside from the two different types of bulbs (HPS and MH), which we touched on before, HIDs are also all available in three different wattages: 400w, 600w, and 1000w. This gives you some flexibility when it comes to the amount of lumens you need to provide for your plants.

Single-Ended and Double-Ended Lights: HID bulbs are also available in both single-ended and double-ended varieties.
Single-ended grow lights have one socket that. A long, wide bulb that contains the arc tube and has a base that’s held up on each end by a frame wire is screwed into this socket.
Double-ended grow lights have no frame wire and work instead like fluorescent tube bulbs: Two small wires support each end of the arc tube and fasten back into the reflector sockets. These double-ended bulbs are much thinner than single-ended ones, and they’re filled with different gases and chemicals.
Double-ended grow lights really pack a punch in terms of lumens compared to single-ended lights. They’ll give you at least 15 to 20 percent more lumens. So you’ll definitely be able to get some intense light from these HID grow lamps if that’s what your plants need.

How Do HID Grow Lights Work?
What Are the Advantages of HID Grow Lights?
 

HID grow lights offer some unique benefits that you don’t typically get with LEDs. This comes in the form of their heat and light intensity.

HIDs Generate Useful Light and Heat Energy: Heat isn’t necessarily a bad thing. HIDs give off both light energy and heat energy, which have been proven to help plant and flower growth. In fact, a lot of plants that don’t get enough heat energy won’t experience optimal growth.
HID Wavelengths Mimic the Sun: Typically, you’d grow your plants outdoors. In an indoor grow room, your plants aren’t exposed to natural sunlight. HIDs’ wavelengths mimic those that come from the sun, which is what helps plants thrive.
HIDs Are Less Expensive Than HIDs: Even at their most intense, HID grow lights are more affordable to buy than LEDs.
As great as an HID grow light’s heat may be for your plants, you’ll also want to keep an eye so that temperatures don’t reach extremes.

Too Much Heat Can Harm Your Plants: HIDs run really hot, so if they’re too close to your plants — or if they accidentally touch them — your plants will burn. Heat is helpful, but too much of it can be dangerous, and HIDs can reach extremes if you’re not paying close attention to them.
High Heat = More Cooling Equipment: If your grow room already has enough heat that’s good for your plants, you’re going to be spending more energy (and money) on cooling equipment to get rid of excess heat.

How Do Wavelengths and Lumen Output Compare?

Since HID and LED grow lights operate in different ways, this affects both their wavelengths and the way their lumen output works.

LEDs are versatile because they’re able to pinpoint specific wavelengths of light with each diode. These diodes can then be supercharged depending on their makeup — lens, chip wattage, number of chips, number of diodes.

This ability to be supercharged and target specific wavelengths is what makes LEDs an optimal choice for successful harvests, regardless of what type of plant you're growing. That means better yields for your indoor garden.

HIDs, on the other hand, have a more limited spectrum to work with that’s not customizable. That said, these types of lights offer their own benefits for plants in terms of intensity.

Specifically, HIDs are able to generate plenty of energy and heat, and as such, they can stimulate plants a bit better. This is because HIDs provide both light and heat energy that’s beneficial for plants.

To recap:

If you want a grow light that’s strong, flexible, and customizable, LEDs have the edge there.
If you’re looking for something with a good amount of beneficial heat and light energy, HIDs are the better choice.

LEDs or HIDs?
When it comes to your indoor garden, both LED and HID grow lights would make excellent options.

Finding the best grow light isn’t just about a single factor, but rather multiple considerations including light intensity, wavelengths, ease of use, and, of course, your budget.

Why you should consider LED grow lights:

LEDs have huge capabilities thanks to their diverse wavelengths, diodes, and chip strength.
LEDs don’t generate a lot of heat, so you’ll save on cooling equipment for your grow room.
You get a great amount of intensity with LEDs.
Why you should consider HID grow lights:

HIDs offer a natural, warm, sun-like quality that has the potential to outperform pinpointed wavelengths.
HID lights are much more affordable at checkout than LEDs.
HIDs are much easier to use, making them an excellent choice for growers of all skill levels.

Should I Use an HID or LED Grow Light in My Grow Room?
Whether you’re looking for an HID grow lamp or LED grow light, there are tons of great options out there for you to choose from.

The good news is that you really can’t go wrong with either type of light!

At the end of the day, you’re the only one who knows what will work best for your grow room and your plants.

Just keep in mind:

If you need unique spectrums and lots of flexibility, LED lights are probably the way to go.
If, on the other hand, you just want a good amount of lumens and the ability to grow healthy plants without breaking the bank, you’re better off saving your money and going the HID route. Buy led grow lights in New Zealand: https://ledgrowlight.co.nz/

Now you’re ready to choose the perfect light for your grow room goals. Whatever option you go with, here’s to some great yields!

Succulents are popular for two simple reasons: they are beautiful and nearly indestructible.

Technically, a succulent is any plant with thick, fleshy (succulent) water storage organs. Succulents store water in their leaves, stems, or roots. These plants have adapted to survive arid conditions throughout the world, from Africa to the deserts of North America.

Fortunately, this adaptive mechanism has resulted in an incredible variety of interesting leaf forms and plant shapes, including paddle leaves, tight rosettes, and bushy or trailing columns of teardrop leaves.

As a group, succulents include some of the most well-known plants, such as the aloe and agave, and many almost unknown plants. Cacti are a unique subset of the succulent group. Succulents make excellent display plants in dish gardens.

No matter what kind of succulent you're growing, the rules are pretty similar among the different species. Here are the general rules for growing top-quality succulents.

Southern Light
Succulents prefer bright light, such as found on a south-facing window. Watch the leaves for indications that the light level is correct. Some species will scorch if suddenly exposed to direct sunlight; the leaves will turn brown or white as the plant bleaches out and the soft tissues are destroyed.

On the other hand, an underlit succulent will begin to stretch, with an elongated stem and widely spaced leaves. This condition is known as etiolation. The solution is to provide better light and prune the plant back to its original shape. Many kinds of succulents will thrive outdoors in the summer.

Temperatures for Growing Succulents
Succulents are much more cold-tolerant than many people assume. In the desert, where there is often a marked contrast between night and day, succulents thrive in colder nights, down to even 40 F. Ideally, succulents prefer daytime temperatures between 70 and about 85 F and nighttime temperatures between 50 and 55 F.

Watering Succulents
Succulents should be watered generously in the summer. The potting mix should be allowed to dry between waterings, but do not underwater.

During the winter, when the plants go dormant, cut watering back to once every other month. Overwatering and ensuing plant rot are the most common causes of plant failure. Be aware, though, that an overwatered succulent might at first plump up and look very healthy. However, the cause of death may have already set in underground, with rot spreading upward from the root system.

A succulent should never be allowed to sit in water. Overwatered plants are soft and discolored. The leaves may be yellow or white and lose their color. A plant in this condition may be beyond repair, but you can still remove it from its pot and inspect the roots. If they are brown and rotted, cut away dead roots and repot into drier potting media, or take a cutting and propagate the parent plant.

An underwatered plant will first stop growing, then begin to shed leaves. Alternatively, the plant may develop brown spots on the leaves.

Choosing Potting Soil and Fertilizer
Succulents should be potted in a fast-draining mixture that's specifically designed for cacti and succulents. If you don't have access to a specialized mix, consider modifying a normal potting mix with an inorganic agent such as perlite to increase aeration and drainage. These plants have shallow roots that form a dense mat just under the soil surface.

During the summer growing season, fertilize as you would with other houseplants. Stop fertilizing entirely during the winter.

Divers get to experience beauty unlike anything we will ever see on land. buy diving equipment for Water Sports.
Coral reefs only add to the incredible natural beauty that exists beneath the water, and they are often the most sought out diving spots.

With so many coral reefs the world over, it’s often difficult to even know where to begin.

While we definitely don’t want to count any coral reef out, these top 5 are definitely the ones you do not want to miss.

The Great Barrier Reef
Australia’s Great Barrier Reef is the largest coral reef on the planet. It includes both inner and outer reefs along with stunning coral and exotic fish; the likes of which you will not see anywhere else.

Make sure to plan your trip during the dry months to ensure that the weather is nice and the water is nice and clear.  You’ll see a more diverse collection of coral than you’ve ever seen along with amazing marine life.

The Palancar Reef
Located in San Miguel de Cozumel, Mexico, the Palancar Reef is often described as a garden of sorts.  The incredible vibrant colors of the coral look like nothing short of a flower garden, and you begin to wonder where such lush colors came from.

Palancar Reef is so beautiful, in fact, that many divers refer to it as the “underwater Garden of Eden.”

If you’re looking for something that outdoes all others and will completely take your breath away (just be careful, you don’t want to run out of air), the coral, lobsters, barracudas, and stingrays of Palancar Reef are calling to you.

Raja Ampat
Many will tell you that a coral reef is only as good as its numbers. If this is true, then Raja Ampat should definitely be topping the charts. This reef in Indonesia has a staggering 600 different species of hard coral for your viewing pleasure, along with over 1200 different varieties of fish!

Here’s why Diving In Indonesia is CNN’s favorite.

Raja Ampat is really unique in that its reefs are in immaculate condition. Somehow this has remained a relatively unexplored spot, despite its beauty. This is good news for you; you’ll not only get to see untouched coral reefs, but you won’t have crowds or wait times to deal with either.

Grand Central Station and Chimneys
Located in Fiji, this particular coral reef is actually known as the “soft coral capital of the world;” that’s a pretty serious title to be carrying.

Carefully and beautifully preserved by the Namina Marine Reserve, Grand Central Station and Chimneys boasts over 1,000 different types of invertebrates, 400 corals, and over 400 marine plants; and these only include the ones that have been documented.

Diving here will be like dessert for your eyes with everything from mangroves to sea grass beds.  There are also incredible walls covered in sea fans, sea sponges, and crinoids.

As if that’s not incredible enough, you’ll also see plenty of bottlenose and spinner dolphins as well as various turtle species and whales.

Belize Barrier Reef
Ranked number two in terms of size, the Belize Barrier Reef offers an incredible assortment of corals, plants, sea creatures, and fish.

Amazingly, this coral reef actually has over 300 documented species of fish and 65 different types of coral.

If you’ve had the opportunity to dive in other coral reefs, you’ll find that the coral here is even more exquisite. The shape and size of the coral combined with the presence of turtles and manatees makes the Belize Barrier Reef a totally unique experience.

Why You Should Grow Medical Marijuana Indoors
Marijuana is an easy to grow plant that naturally thrives outdoors, but there are some specific benefits to growing medical marijuana indoors. The largest reason is that indoors, you completely control the results. This is important because when you are consuming marijuana to relieve specific symptoms, you want to know exactly what you are consuming, and you want the highest quality. When growing outdoors, there are more variables (including wildfires, drought, storms, and animals) and therefore, more uncertainty.

Create a hygienic environment
One variable that you are in complete control of is the environment. Indoors, you can ensure a hygienic environment because you are responsible for creating it. When growing cannabis for medicinal use, it should be free from germs, fungus, parasites and any other microscopic organisms that could cause illness. If the patient has a weak immune system or has trouble breathing due to allergies, insects, mold spores and pesticides should be avoided at all costs. A hygienic environment can only be guaranteed when growing indoors.

Creating a hygienic environment also means creating the ideal climate. Climate problems such as high humidity can lead to hygiene problems such as mold. If this occurs outdoors, there is little that can be done. In an indoor environment, simply adjust the environment to prevent this from occurring.

Enjoy multiple harvests
Outdoor growing is great but growing with the seasons is not. When you depend on Mother Nature to provide for your plants, you will be left with only one harvest per year, especially if you live far from the equator. An interesting fact, however, is that cannabis is an annual plant and has a few flowering periods per year. So, the number of harvests is less about the plant and more about the environment. When you grow indoors, you can create the right conditions for a cannabis plant to produce more than one harvest in a year

With practice, you could hypothetically harvest six times per year because it takes a plant two months to mature and flower. That means you could grow cannabis year-round when done indoors. You only need two rooms, one for the vegetation phase (where you give it 18 hours of light) and one for the flowering phase (where you give it 12 hours of light). In the flowering room, your plants could mature while cuttings stem and sprout in the vegetative room. Once the cuttings mature, move them into the flowering room, and by then, it should be about time to harvest the first group that has finished flowering. This simple method enables you to grow up to six harvests annually.

Have a good time
Indoor marijuana growing may not be easy, but it is definitely rewarding. It can also be a lot of work and is something that takes a lifetime to master due to all of the subtleties. Growing marijuana indoors is a craft, and many crafts are fun.

For the chronically ill, crafts are a wonderful diversion, because they provide a learning experience that is stimulating to the mind. Growing marijuana can help patients focus on things other than their health. Learning about how the cannabis plant grows can instill a deep appreciation for healing plants, in general. Plus, there’s not much more relaxing than watching a plant grow.

If medical marijuana could be defined as high-quality cannabis designed exactly for the condition you are intending to address, indoor growing is the best way to grow it. That doesn’t mean it’s always the best decision, though. Indoor growing takes a lot of effort and time. It also costs more than growing outdoors. Most of all, in some areas indoor growing is illegal, whereas outdoor growing is not. Do the research to determine your best option and always stay safe.

Setting up Your Indoor Grow Room
If you’ve decided to grow your medical marijuana indoors, you’ll need to do a little planning. You are going to provide everything that nature does, and it’s going to take some work. Growing medical marijuana is about focusing on quality. You want to produce “medicine” that does its job well, doesn’t introduce new problems into your system, and is always available when you need it. You can do this by keeping your plants healthy, harvesting at the right time and properly drying and curing your harvest. It all starts with the right setup.

Lighting
Some gardeners prefer to use led grow lights, most gravitate toward 1000 watt led grow light found on the internet and at indoor garden shops. Keep in mind, Indicas and Indica hybrids need less light to thrive than Sativas and Sativa hybrids.

Lighting is essential to your plants because they use it (along with water and carbon dioxide) to produce sugar and release oxygen. Sugar is the primary building block for tissue growth—including bud growth—and is used to power metabolism. The more light energy the plant receives and can use, the faster and more dynamic the growth will be.

Temperature and Climate
Your plants need the perfect temperature and climate to thrive, but all of those lights make it hot. In order to maintain adequate temperatures, the heat produced by the lamps needs to be eliminated. The two best ways of achieving that goal are an air-cooled reflector or a water-cooled reflector. These units will enclose the lamp in a cooling system that is not a part of the grow space. The air or water is odorless and can be used for heat in another space.

Temperatures can also rise due to the absorption of light, much of which is converted to heat. The humidity will also build up causing the plants to practically mine the CO2 from the air. Without CO2, the plants cannot produce the vital tissue-building sugars, and growth will stop until the CO2 is replenished. Because of all of this, the growing space must be ventilated with fresh air.

Of course, simple ventilation can be achieved by opening a curtain or door, but some gardeners prefer complex methods like using flexible tubing and an inline fan. You could have the ventilation line controlled by a thermostat or humidistat, but some growers like to keep the ventilation going whenever the lights are on.

Planting medium
Indoor gardeners can choose between growing in planting containers with planting mix and using hydroponics. Hydroponic systems use a non-nutritive rooting medium that provides nutrients by adding fertilizer to the water. Using hydroponics effectively requires more skill and accuracy because there are no natural buffers in the medium. Read this guide for more on hydroponic growing.

Get Growing
Once you’ve set up your indoor grow room it’s time to start planting. Whether you’re starting with sexed seedlings or clones, place your plants in containers filled with a high-quality enriched indoor planting mix. For the sake of convenience, use three-gallon containers. They aren’t that heavy, and they also give the roots enough room to grow.

Set up your room so that you can leave the lights on for 18 to 24 hours per day. The longer light periods will help the plants reach the flowering stage faster.

After about three weeks, the plants should be between 1 and 1.5 feet (30 to 45 cm) tall and ready to flower. At this point, you should change the light cycle to 12 hours of darkness and 12 hours of light. Use an automatic timer so that the light goes on and off at the same time each day without running the risk of human error. It’s important to avoid interrupting the dark period, even briefly, with light. If you must use light, choose green light – it is the only safe light to use while in a dark garden.

You’ll also want to change the fertilizer to a special flowering formula. In 7 to 10 weeks, depending on the particular variety, the top buds will be ripe. Make sure any buds hidden underneath the top canopy are left on the plant. They will ripen in around 7 to 10 days.

Optimizing your Grow

The basic idea behind growing indoors is quite simple, but if you want to have the best results, you’ll want to do a bit more. These steps will not only result in high-quality medical marijuana but also lower your costs so that you can focus on growing more of it.

Choose full spectrum grow lights. LED lights are not as powerful as other options, but they use less electricity and produce less heat. Plus, the full spectrum wavelength matches what plants use in nature resulting in a more natural grow.
Grow feminized seeds. If you accidentally introduce a male plant into your garden, you could ruin an entire harvest and have to wait another 2 months to redo it.
Cultivate “fast-finish” strains. Certain strains will finish flowering in eight weeks (instead of fourteen). A shorter flowering period means more harvest per year.
Learn and use training techniques. Techniques such as Sea of Green and Low-Stress Training can help boost yields while also lowering costs.
In addition to saving money, you may also want to use your ability to “grow your own medicine” as a way to keep it as natural as possible. When you buy marijuana from a dispensary or dealer, you are never quite certain if it has been treated with dangerous chemicals. When you are in control, you do not have this worry, as there are plenty of ways to reduce the use of chemical while growing medical marijuana. Whether you decide to use natural nutrients, natural pest control, or even create natural pesticide sprays, you can optimize your garden to produce the most natural and cost-effective “medicine” available.

A Note on CBD Strains
Although, as explained above, there isn’t a specific “medical marijuana strain,” many medical users enjoy high amounts of CBD in their marijuana. When considering strains, therefore, it is important to understand what CBD strains actually are. Generally, a CBD strain is any strain with at least 2% CBD. Most strains today produce less than 1% CBD; therefore, 2% is enough to be considered “high CBD.” However, for therapeutic purposes, the ratio of CBD to THC is much more important than the actual percentage. For example, a strain with a 1:1 THC to CBD ratio will have much more mild effects than one with a 2:1 THC to CBD ratio. This is simply because CBD can minimize many of the effects of THC.

If you are looking for a strain with high CBD levels and limited psychoactive effects, you’ll want something with at least 2% CBD that also has a ratio of CBD that is greater than THC. In general, autoflowering strains tend to have higher CBD because they are created by crossing hemp plants with an established strain. The hemp naturally has CBD, making many of these varieties naturally high CBD strains. You can also find non-autoflowering strains that have been specifically bred for CBD. These strains are often available as clones.
Growing a high CBD strain is less about you and more about the plant as CBD levels are based on a plant’s genetics. You can never make a cannabis plant produce more CBD than it is designed to do. You, can, however, provide the optimal environment so that the cannabis plant can reach its full potential.

When growing high CBD strains, you want to take the same steps as you would any other type of marijuana, such as not harvesting too early and keeping your plants healthy. However, since CBD is much more prevalent in hemp (a cousin to marijuana) some alterations to the growing environment might prove beneficial. Wild hemp tends to grow well in warmer soil, with warmer air and with less rain than Indica and Sativa and the same may be true for high CBD strains. Therefore, when growing these strains indoors, make sure your grow room is warm enough (but not too warm) and that you don’t overwater your plants.

Growing marijuana indoors is one of the best ways to ensure you have an ample supply of natural relief. Not only is it sometimes fun, but it also isn’t impossible. With some preparation and time, you can grow high-quality cannabis that is specifically chosen for your medicinal needs. When you grow indoors, the results are up to you, because you’re in control.

Carbon filter, great to get rid off the smell
For this, you can use an odor filter, usually some sort of carbon binding contraption that traps molecules in it. There are a number of different options for this sort of device, and they work far better than trying to spray the air with some other powerful scent in an attempt to mask the odor.

Most odor filters are cylinders made out of metal with carbon in them. Filters are placed inside outlet propellers so that the air that leaves the growing area is clean. This works because the carbon sucks up the marijuana scent as it passes over it.

To help the carbon last longer, use cotton. Wrap the cotton around the cylinder – it will filter out extra dust particles. This will extend the life of your filter, but it’s not a permanent solution.  You will need to replace the carbon every 25 weeks, otherwise it may start to fail.

LED grow lights bring definite benefits, but choosing the right product usually proves to be quite challenging. The wide array of models available on the market, confusing statements from manufacturers and misleading product descriptions are some of the main reasons behind this.

Starting off with the wrong set of lights can be detrimental to your growing efforts, so making an educated purchase is a must. There are many factors and properties that need to be considered, but you should also be aware of your growing purposes, location, and other specifics involved. Following is a list of the most important things you should look for when making your choice.

1.Quality Build & Materials
Durability is one of the best things about LED lighting. If a lamp is built using quality materials, it can last for about 10 years. This is a long time during which you won't have to worry about making any changes to your set-up.

2. Brand Reputation
There are many different brands on the market and each one provides slightly different products. This makes the choice all the more difficult, considering that not all options are of equal quality.

In case you're wondering between different light choices where price and appearance are almost equal, taking a look at the brand can provide the answer. As in other fields, a company with good reputation, long history and extensive research and development efforts is more likely to have a good product.

3. Electricity Output & Consumption
Your LED grow lights will have to operate for at least 10-11 hours each day, which in turn will lead to increased electricity bills.

Making an informed choice and reading the detailed product description can save you troubles in the future, therefore you should always check how many units is the total output. The options go up to 1000w led grow light but you shouldn't settle for anything less than 300W. Have in mind that the higher output helps compensate for any wattage loss.

4. Low Heat Output
This is one of the most important things when choosing LED lights, as it contributes to two main factors – plant protection and durability.

The lights are in constant proximity to the plants and having low heat output guarantees that there won't be any damage but also enables for a smaller distance between the lamp and the plant.

Also, a light with higher heat output would burn out more quickly and will need to be replaced sooner. Well balanced low heat output LED grow lamps let off less energy as heat and have aluminum heat sinks attached.

5. Quality Semiconductor Chip
The semiconductor chip is the LED light`s core and serves the purpose of converting electricity to light, but also has a part in determining the wavelength. It is advisable that you look for a light that has a chip of at least 3 watts, otherwise it won't be able to provide sufficient illumination.

6. Consider What You Are Growing
The lighting you choose must be suitable for the type of plants you're growing. All LED lights will do the job to some extent, but certain models are made to address specific plant needs, as plants needs different kinds of wavelengths during each growth stage.

For example, if you are growing heavy crops like tomatoes, you will need a different light to maximize its growth than if you were growing flowers. Also, do you need lights only for vegetative cycles, flowering or is it a complete growing process?

7. Plant Growing Space
Space availability is a vital factor when purchasing lighting as it determines the amount and size of lamps you need.

The first thing you need to do is measure the exact size of your garden. Then you need to find out the lighting area size of the lamps you're considering in order to determine the exact number you need.

The general guideline most growers use is that you need 32 watts of actual power per square foot if you're growing high-light plants like tomatoes. Low-light plants like lettuce need somewhere between 11 and 18 watts per square foot.

8. Full Spectrum LED Grow Lights
Although plants can grow under almost any type of light, efficient photosynthesis requires different wavelengths and some of the best led grow lights can provide plants with the full spectrum necessary throughout each growth.

For example, in order to grow most efficiently, many plants need light in the red and blue spectrum, but also infrared and ultraviolet, depending on the stage. A powerful full spectrum LED grow light enables you to cater to the plant's specific needs by providing the proper photosynthetically active radiation values.

9. Easiness of Use and Flexibility
Sometimes you'll have to adjust the position of your lamps, based on the plant type and growth stage. Quality LED lamps are efficient, but also easy to use and will let you fine tune their placement with little effort.

Also, it is important that the wavelength and light intensity are adjustable as well. Look for products that are easy to maintain and ready to use straight out of the packaging.

10. Warranty and Return Policy
Most manufacturers also provide a guarantee on the parts of the light. Some parts of LED lights function independently, so if you're waiting for a spare to arrive your light can still do its job.

Full spectrum LED lights are becoming increasingly more popular due to their high efficiency and durability. Although selecting the right model can be daunting due to the saturated market and sub-substandard products, following these 10 criteria will help you find what you're looking for. Don't settle for cheap and look for lasting quality.

Requirements for Growing Hydroponic Herbs:

Consideration for growing hydroponic herbs include: light, nutrients, temperature, humidity, and pH level. Once these factors are controlled, hydroponics provides a less time-consuming and superior growing medium versus conventional soil.

While propagating herbs from cuttings is a viable option, starting your herbs from seed is the most popular method for growing hydroponic herbs. Moistened propagation cubes work well for seedlings, as does a conventional soil mix. Germination typically takes 1-3 weeks. Once the seeds are of adequate size and are displaying their true leaves, the plants may be transported to your hydroponic grow system. It should be noted that seed germination is difficult when growing lavender, bay leaf, rosemary, white sage, and flavored mint (such as chocolate mint or orange mint). In these cases, a plant from a cutting (or an established plant bought from a garden center) will likely be more successful than growing from seed.

Herbs need – at the very least – 6 hours of bright, unobstructed sunlight per day. A south-facing window may provide adequate lighting for herbs. Rotating the plant to ensure all sides receive sufficient coverage is advisable. Since many plants – including herbs – thrive on up to 10-12 hours of sunlight per day, grow lights are recommended for extra supplementation, especially if your plants are not receiving the minimum natural sunlight to remain healthy. Standard fluorescent lamps may be sufficient, but their yield is less effective compared to modern LED grow lights. High intensity discharge lights [HID] are also effective – especially metal halide, which are superior for growing leafy herbs. Since grow lights with blue spectrum lighting encourage lush, bushy growth in many varieties of herbs (such as basil), grow lights with blue spectrum capability may be the best choice to grow your hydroponic herbs.

Nutrients – specifically designed for hydroponics – are another key component of growing hydroponic herbs. Combining fertilizer and water create the “nutrient solution.”  It is recommended to drain, clean and re-add a new nutrient solution to maintain optimal conditions. This process should be done at least once a month, although more frequently is encouraged. Methods for providing the nutrient solution include the Passive method (which allows you to decide when and how much nutrient solution a plant needs, without the use of pumps and timers), the Flood and Drain method (when trays and pots are flooded with the nutrient solution using a pump), a Drip System (timer-controlled method using a pump to drip nutrient solution on to the plants), the Nutrient Film Technique (NFT) and the aeroponic method.

There are various mediums to choose from when growing your herbs hydroponically. Some of the most popular include coconut coir, lightweight expanded clay aggregate (L.E.C.A), perlite, vermiculite, lava rocks, and oasis cubes, as well as sand and gravel.  These mediums act as an anchor to the plant, but do not provide the essential nutrients for the plant’s health. Thus, the grow medium you choose is of lesser importance than that of maintaining a continuous supply of nutrient solution.

Room temperatures ranging in the 70-75-degree range are ideal, along with a relative humidity level around the 40-60% range.  As with all hydroponic gardening, maintaining adequate ventilation for your herbs is important. Oscillating fans, as well as ceiling fans, work well. pH levels should be consistently checked to maintain a healthy range between 5.5 and 6.8, depending on the type of herb you are growing.

Keeping the plants bushy allows herbs to be more productive. Pinching off the tops when your plant reaches 6-12” tall will prevent them from becoming too leggy. Herbs do not require a lot of attention once your hydroponic routine is in place, and are a perfect choice for those who want to grow fresh produce all year long in a controlled indoor environment.

It's always easier (and better) to prevent the disease than to cure the patient. That's just as true for house plants as it is for people. Thousands of words have been written on plant diseases and blights; we can read books on insects and plant insect infestation but the number of house plants that fall prey to these ills is infinitesimal when compared with the tremendous majority that die from neglect or from the gardener's lack of knowledge of the habits of the plants themselves.

By far the major cause of failure in the home garden is neglect. Plants need watering, pruning, a time in the sun, proper food and soil, and good living (potting) conditions. They must be provided with an atmosphere in which they can prosper, with a reasonable temperature, proper humidity and enough fresh air. By this we don't mean to say that they must be watched constantly, petted and pampered; or even that all plants need daily attention.

The second big reason for plant failure comes from trying to grow plants in an environment unsuited or badly suited to their needs. Some plants such as Lantana or Morning Glory need as much sun as they can get, and demand a south window; others like the African Violet and various species of English Ivy will flourish for season after season in settings which never receive the sun's rays directly, but which merely get reflected light.

Most plants which are grown indoors possess a fantastic degree of adaptability. They must, in order to survive. The modern home is designed to be lived in by humans primarily, and little thought is given by the architects and builders to the needs of growing things. Yet, a cactus from the desert and a fern whose original habitat is in the rain forests of the South American mountains will live and prosper in the same room, if they have been chosen and then cared for with some intelligence and thought.

Light and Sun

Before you decide on the plants you are going to buy, you should plan the accommodations they are to receive once you get them home. If you live in a house or an apartment with exposures on all sides, it's best to try to plan your arrangement around a south-facing window. A southern exposure gets the most sun, an eastern one next most, then west, with the north-facing windows getting the least.

As we have said, not all plants need direct sunlight; some actually are bothered by it but whereas you can always provide shade in a sunny window, it is harder to try to induce the sun to shine into your north windows in the dead of winter. Therefore as a starter use a southern exposure. Of course, a bay window on the south side of the house is the perfect answer to an indoor gardener's dream. Here you get the sun almost all day long.

Plants grown in sunny windows and that includes almost all of the flowering varieties will tend to turn their blossoms and foliage toward the sun. Since you are growing plants at home for the enjoyment of those in the house rather than passers-by who might look in the window, it is wise to turn the pots every day or two so that the flowers won't grow in a completely lopsided manner.

The basic needs of indoor plants are few, but they need to be satisfied. Then you can enjoy your flourishing indoor plants for years!

Grow tents are a very popular and smart solution and my favorite. A marijuana grow tent is a light proof, rectangular tent where you place your containers with soil or hydroponics system. Usually flood and drain systems or drip irrigation is used in a tent, they don’t work as well with nutrient film technique.

They are black on the outside and totally light-proof, lined with a reflective material on the inside to utilize light more efficiently. Grow tents allow you to completely customize the environment your marijuana plants live in, including temperature, light intensity, humidity, and location. Tents are portable, durable, washable, lightproof and waterproof, and come in a wide range of sizes to suit any hobbyist’s needs.

Full room setup
There are advantages to using a full sized room for growing marijuana. One is that fans can be used to refresh the air. They can also be connected with outside air through, for example, a window. This can work in a cellar because a cellar is (usually) built underground in the earth. The Earth keeps the temperature stable unlike above ground. This means a few fans will be all you need to keep the area cool.

The attic, on the other hand,  is not as good of a choice because it does just the opposite trait. The temperature is highly unstable; it will either be very cold or very hot – depending on the season. The same for rooms and/or wall units facing southward, especially if there are large windows or are on upper floors. During the summer, plants can get quite overheated. Here are some potential room measurements and the light requirements you will want in a room of that size:

9.8 x 9.8 x 8.2 feet (3 x 3 x 2.5 meters) for 2 x 300w led grow light for a fixed system

Remember, make sure your room is properly covered and insulated so that it stays dark during the dark periods. You want to be controlling the lights, otherwise you might end up with a sudden, untimely flowering.

Install grow room cannabis
Keep all of the walls of the grow room covered with something that reflects light, such as white plastic or white paint. The best material for this, however, is tightly drawn Mylar.

Secure you grow room lights. Do this by connecting them to the ceiling with a hook, ring or a pulley. Make sure the electric portions are securely connected and safeguarded from damage.

Next, install devices for air circulation. This could be an exhaust ventilator, an intake fan, or an outlet fan. Avoid long air channels that have curves; they negatively affect the capacity of the aeration. Try and keep the pipe short and straight as much as possible so that your air travels efficiently.

It’s a good idea to install any other devices at the same time. Some examples are measuring devices  such as a hygrometer or thermometer. You’ll also need to set up the substrate (your bottom growing layer) and decide whether you plan to  grow in soil or install hydroponics. Hydroponics are way less susceptible to bacteria then soil, making them a good choice in some cases.

Cleaning your grow room
Cleaning your indoor cannabis grow roomIt is of great importance that your grow room is kept clean. If you don’t keep your grow room extremely clean, you put the plants at risk for fungus, mold, and disease. Disease can spiral out of control very quickly in the warm, humid environment you’ve created. It’s absolutely vital that you don’t let mold or dust accumulate in any out-of-the-way corners or worse yet, on the plants themselves.

Additionally, you want to be careful to keep any animals far away from your plants. While this might not sound like a difficult task, cats are very curious and tenacious creatures, and dogs love to get into trouble. Don’t let them ruin your crop! Besides causing trouble, animals can carry bugs and bacteria that have a high potential to ruin your harvest.

Before and after you begin a new growing cycle in your grow room, its a good idea to disinfect. Clean the whole location with some sort of cleaning agent, just to make sure you won’t be dealing with any latent parasites or bacteria in future crops.

Cleaning up also means cleaning up the waste that your plants create themselves. Inevitably some leaves and foliage will yellow and die off. Make sure you remove these right away. If you do end up having problems with mold or fungal growth, you’ll likely have to abandon that crop.

As alluded to above, growers can take advantage of the way plants develop in nature, essentially hacking the plants to perform in certain ways. One of these techniques is sometimes called ‘forcing.’ Forcing is the process of taking a plant that has been experiencing very long days (long exposure to light, between 18-24 hours) and suddenly switching the light exposure to only about 12 hours. By imitating the change from spring to summer, this technique has the effect of causing the cannabis plant to rapidly begin the flowering cycle. It’s this sort of high sensitivity to changes in light cycles and exposure that make it possible for growers to effectively grow cannabis.

18 hours of light + 6 hours of darkness = vegetation phase

12 hours of light + 12 hours of darkness = flowering phase

A pure Cannabis Sativa strain is not as sensitive to the light changes as some other varieties because it is originally from tropical regions of the globe. Generally speaking, the relationship between night and day is more stable in these tropical regions and changes relatively little between seasons. This is one of the reasons that Cannabis Sativa is larger than other varieties, taking up to 5 full months to reach maturity. Because it becomes so large before flowering, it is not as common for indoor gardeners to use a Pure Sativa strain. Hybrids can be grown without any problems.

If you are growing outdoors, be aware of the zone you are growing in and make sure that the climate is right. It’s very easy for a Sativa to die or be hurt in cold weather before it gets a chance to mature or flower if it’s being grown outside of its native tropical zone. This can be ameliorated somewhat by the use of a greenhouse.

Feel free to experiment and do your own research into light cycles. Every cannabis strain will react slightly differently to different stimuli. The bottom line is that the light cycle is very important to the end product harvested. When cannabis plants receive the right amounts of light in the right cycles, the plant will thrive. A plant flowers when the ratio of light/dark is equal while they will stop flowering when the periods of darkness are interrupted by light.

Regardless of whether you choose to grow your cannabis indoors or out, you are going to need a good source of light. More light means more weed. In nature, plants use the sun. Light is the force which makes photosynthesis possible, converting that energy into usable glucose and oxygen. Photosynthesis splits hydrogen from oxygen and then combines with oxygen and glucose.

Glucose is the fuel of the plant, the chemical that powers the basic building and growing functions that carry Cannabis from seed to smoke. Your plants use a lot of light to produce it, and, in general, the more, the better. The important thing to remember is to keep the rest of the environment balanced with whatever amount of light you’re applying. You need to monitor the temperature, humidity, and levels of carbon dioxide in the air. Beyond that, your plant requires adequate nutrients and plenty of water.

Your eventual goal as a grower is a high-quality yield of buds, and this will be determined in great part by the amount of light your plants receive. Cannabis is especially receptive to heavy lighting, and the quality and size of your flowers will be determined in part by all those lumens!

In general, you want a minimum of 30,000 lm per 10 square feet in your grow room. With the proper balancing of the environment, you can go all the way up to 80,000 lm per 10 square feet. Don’t do this unless you are planning on devoting a lot of time, energy, and money into making sure that the environment is constantly getting the necessary tweaks.

The flowers or buds of the Cannabis plant are comprised of the stalk, the leaf, and the calyx. If a plant receives light in abundance, then the plant will focus more on producing calyces than making flowers. The reverse holds true. If a plant isn’t getting enough light, then more energy will be devoted to the production of leaves, and you will end up with a worse harvest. This is because the plant is trying to compensate for the low amount of light by making extra leaves to pull in sunlight.

The spectrum of light your plants are receiving affect growth a great deal. The sun has a very full spectrum, but you can control the types of light you are using in your grow room to achieve some excellent effects. Photosynthesis and a number of chlorophyll related reactions are stimulated by the orange, red and blue sections of the spectrum. Phototropism is controlled by colors ranging from blue to ultraviolet. This is the phenomenon by which a plant grows itself into the best possible position for capturing light.

The most important general rule to remember about light and Cannabis cultivation is that red spectrum colors induce flowering, while blue spectrum colors promote growth.

The cycles or periods of time during which your plant receives light is also important. While your plant is growing, it should be receiving about 18 hours of light for every 6 hours of darkness. When it’s time to flower, you’ll want to switch to 12 hours of light and 12 hours of darkness (hint: there are only 24 hours in a day). One of the really nice things about indoor growing is that you have full control over the light. You choose how the passage of night and day will occur, and so you should be mindful of providing it in ideal proportions so that your plant thrives.

Different grow lights marijuana

If you’re growing indoors, you’ll have to decide how best to set up your own lights. There are a lot of different options when it comes to the lighting system, and there are a lot of opinions, too. Lighting systems will vary in intensity, spectrum color, and the underlying technology. It will come down to the size of your grow room, your electrical needs, and how much time and money you’re willing to invest into lighting up your grow room.

When you choose a light system, first plan on how much light you need to use, then compare that to how much light you can realistically provide for the plants. If you live in an old house with direct current, it probably won’t be much! Be realistic, and remember that lights use up a lot of power.

When it comes to lighting, you have a lot of different choices. We covered some of the basics in types of lighting in the last section. In this section, we’ll cover more about the different choices you’ve been presented with, and discuss some of the pros and cons of the different lighting setups. Below we’ll offer a general look at some of the other lighting options you’re faced with as a Cannabis cultivator. Many growers argue about which lights are the best, but, in general, every type of light specializes in a certain phase of growth or a certain type of job. It’s up to the grower to decide how much time and money they want to invest into their lighting systems.

CFL – Fluorescent lights
In the early days of Cannabis cultivation, fluorescent grow lights were used by growers to simulate the sun, just as they had been used for many years by farmers and botanists for indoor growing and early germination in cold climates. Unfortunately fluorescent lights are expensive and you require a lot of fluorescents to simulate natural sunlight. Not only that, but it requires a lot of different types of fluorescent lights to mimic the full spectrum of natural light.

Nowadays, growers still use fluorescent lights when plants are extremely sensitive to heat. This applies to cuttings and seedlings in early stages of growth. Keep in mind, however, that the fluorescent lights still need to be close to the plants themselves, usually about 5 cm away. Fluorescent technology has changed somewhat, too, and now fluorescent lights offer slightly higher quality growing for Cannabis than they used to. If you’re using fluorescents, you’ll also want reflectors to go with them, to maximize their efficiency and save yourself some energy.

HID – High intensity discharge lights
High-intensity discharge grow light were first invented for a huge scale, for use in public arenas and stadiums. These sorts of light are very powerful, and they’re used by a lot of botanists and horticulturists to grow lots of things besides Cannabis. But they do work quite well for Cannabis, so let’s talk about them. Within the various types of HID light, we have mercury, metal halide, and sodium vapor light. We’ll cross mercury lights off the list right away because their lumen to watt capacity is too low for them to compete with the others.

MH – Metal halide lights
Metal halide grow lights produce light by arcing an electric current through mercury gas mixed with some sort of metal iodide such as thallium, thorium, or sodium. The light that it produces falls into a perfect range of the color spectrum for the growing phase of Cannabis. In particular, it’s good for producing foliage. Plus, it’s flexible: 1000 watt metal halide lights can be used to induce the flowering period in plants. Growers in the United States used metal halide lights for a long time after the introduction of HID lighting, and they performed well for all phases of plant growth.

HPS – High pressure sodium vapor lights
In the mid-80’s, when communication began in earnest about growing practices and how they differed in the US and Europe, growers and cultivators discovered a couple unusual differences. First of all, Americans were using a lot more power than their European counterparts. One of the reasons for this is because most Europeans were using horizontal reflectors and HPS grow lights, whereas Americans were using vertical reflectors and metal halide light.

HPS lights have the ideal color range for Cannabis plants during their flowering phase while metal halide are superior for the growth phase. They function similarly to other HID lights and create light by arcing electric current through a bulb containing xenon and sodium gas. They emit a dull pink glow that quickly turns into an orange-pink light once it warms up. Again, these lights work spectacularly for indoor cultivation, especially for a plant going through the flowering phase of growth.

You can purchase HPS lights in a number of different strengths: 250w, 400w, 600w, and 1000w. Don’t even think about using the 1000w light unless you’re growing a whole field in an underground bunker. In order to take advantage of the strength, you have to cool your grow room with an air conditioner.

Your best bet is to purchase two 400w or 600w HPS lights: these will evenly diffuse light for your plants, and they aren’t overly lot so you have a low risk of heat damage.  Keep in mind that you might want to use a fluorescent light in conjunction with your sodium vapor light.

LED – Light emitting diodes
Led grow lights weed

LEDs (light emitting diodes) have become ubiquitous in the lighting world over the last decade. While not necessarily the ideal light for growing cannabis, LED lights offer several advantages.

First of all, they are low voltage, which means less money spent on upkeep and electricity to keep them running. Coupled with this, they produce very little heat, which means you don’t need to worry about overheating your grow room if you use LED lights. It also further reduces your reliance on ventilation and fans, adding even deeper energy savings. In fact, depending on your operation, you may very well need to heat the room if you are using LED lighting.

For growers prioritizing privacy, LED lights offer an additional bonus— the low heat makes LED lighting virtually impossible to detect with thermal imaging techniques commonly used to spot the infrared heat of more conventional HPS lights. LED lighting is also quieter than the other lighting options, without the background hum emitted by HPS lights.

Remember that not all LED lights are created equal! Be sure to check your bulbs and make sure that they are high-wattage and have a high lumen value. The higher these are, the brighter your light will be. You also want to make sure that LED lights you choose have been specifically manufactured to emit light at the full spectrum of color your plants need for proper photosynthesis.

LED lights do have a higher initial investment than some of the cheaper options, which can cause some growers to be skeptical about using them. Then again, they are very efficient. LED lights waste far less energy as heat, assuming the room doesn’t need to be heated, and those savings on electricity will pay for themselves in just a couple years. You also don’t need to worry about setting your grow room on fire, and LED lights last for a long time. Some manufacturers advertise more than 100,000 hours of life in their LED bulbs, which gives you enough time for almost ten years of harvesting. Click here for the best led lights for marijuana plants.

Above all, be smart about using what you’ve got. It’s important to have lighting, but you need to plan it out, too. You can’t just fill a room with ultra-high wattage lights and expect your plants to thrive. Don’t waste valuable power, and learn how to make use of your resources.

Positioning lights and plants
In this section, we’ll run through some basics on positioning your marijuana plants and lights, as well as covering some tips and techniques for avoiding stretching in your plants. This section will help you maximize the growth and bud efficiency of your plants, so pay attention.

The leaves of the Cannabis plant uses light for photosynthesis, and the plant will orient itself towards the light it needs. Outdoor, it’s easy to see this phenomenon in other plants, and you’ll see it yourself in indoor growing operations. If you put the Cannabis plants too close together, they will prevent each other from getting light and less photosynthesis will take place. Obviously this will cause major issues for your plants. Make sure that every plant gets plenty of light.

You also want a fairly uniform amount of light cast onto the plants themselves.

It’s important that the buds on your plants all get the exact same amount of light, even if they are of different sizes. To do that, you need to make sure that each plant gets plenty of space. You don’t want any plants to hog all of the light and prevent its smaller relatives from growing.

Giving your plants plenty of space from one another will also help air circulate, which is extremely important for maintaining stable levels of humidity. Let the plants touch each other only a little, or you risk buds malforming. This could encourage bacterial or fungal growth.

If you aren’t growing a lot of huge plants, you can keep them together with small gaps. Trimming isn’t the best solution, but sometimes growers need to make do with limited space. Above all, your plant needs reliable and uninhibited access to light in order to thrive. Don’t let the plants crowd each other out!

An easy mistake for many growers is placing their Cannabis plant too far or close to their lighting fixtures. Obviously if a plant is too far from a light, it won’t be getting the energy it needs to produce a healthy crop. These sorts of plants will grow up to be too thin and spindly, lacking the structural integrity to bear heavy yields. The opposite is true for lighting that is too close. It will be too hot, and plants can dry out and even die if they are badly burned by a powerful light source.

One thing to remember in regards to light and positioning is that you want each plant to receive the maximum benefit possible from the lights. That means smaller or shorter plants should be put closer to a light source than big ones so that they receive equal amounts of light. Although this seems simple, it’s a common oversight for new growers (and sometimes old ones.)

Utilizing this technique also offers a grower the advantage of keeping smaller plants out of the shadows of the larger ones, an issue which would compound the lack of light. If your plants are of similar sizes, it’s not a bad idea to move them or the lights around periodically to help ensure that they are all getting equal shares of the bright stuff.

Use reflective materials
You want every little bit of light to get to your Cannabis plants. The old saying “Waste not, want not” applies quite well to the cultivation of Cannabis. One of the first steps in preventing light loss for your growing operation is to reflectors in addition to your lights. This means you’ll want your lights positioned horizontally so that the reflection process is maximized. Vertically aligned reflectors inevitably lose more light than the horizontal ones.

Also, try not to use any reflectors with single parabolas. Double parabola reflectors are far better at reflecting light. This goes for closed reflectors too. Closed reflectors function better because they direct light more efficiently into a tighter focus. That means you want horizontally installed double parabola closed reflectors in addition to the lights you choose.

The two most common materials for reflectors are aluminum, both beaten and smooth. Each type of aluminum does a good job of reflecting light, but beaten aluminum will help diffuse the light. Some growers suggest that just painting the walls of a grow room white or using linoleum paneling is good enough reflectivity for your interiors. This is, of course, after the actual reflectors themselves, but your best bet is always going to be Mylar grow tent.

Mylar is extremely reflective and does a great job of helping you maintain a stable environment for your plants.  There’s a reason it’s used by growers all over the world. Just make sure you draw it tightly over the walls so there aren’t a lot of nooks and crannies in the surface to cause the light to dissipate.

Safe installing
When you’re setting up a lot of different lights and reflectors, you should take extra care, especially if you are a new or amateur grower. After you’ve set up all the necessary lights and electrical equipment, you’ll be dealing with massively strong currents. If things aren’t set up properly and carefully monitored, you could experience power surges, outages, shocks, and fires. At high voltages, these can all be extremely serious issues, and very dangerous.

Not only that, but if you’re using a hydroponics system like many indoor growers, you’re going to have a lot of water flowing around in that grow room. Water and electricity don’t mix well. Make sure everything is well grounded and safe in case of any sort of surge or spill. If you’re either a new grower and lack experience with electricity and wiring, leave these things to a professional. If you hire a professional make sure to check their background and make sure they know what they’re doing.

Because of the inherent risk of spills and floods in a grow room, make sure that all of your electrical equipment is raised up off of the ground. Keeping it all above ground will help prevent any short circuiting if the room floods.

Real plants do wonders for aquariums, providing fish with oxygen and even food. They keep the water chemistry more balanced, and provide scenery for you and hiding places for fish and other tank inhabitants. They're easy to care for, too.

Select the plants you want to grow. It pays to do a bit of reading at this point, so check out aquarium forums and other sources of information. Consider the tank size, the scene you wish to produce and the size you want your plant(s) to be. Remember, plants grow! Want something with lots of leaves, or more of a moss? How about something your fish will be able to eat?

You can find tiny, dwarf aquarium plants that grow only an inch or two tall, or obtain much larger plants for larger tanks.

Get a cutting of the plant you want to grow. Either get an inexpensive, small cutting and wait for it to grow larger or purchase a more costly, larger plant. Plants can be obtained at local pet shops, or a hobby specialist online can provide you with cuttings,usually for a small cost. Either way, be careful of what you introduce to your tank. Plants can carry physical inhabitants from snails and shrimp to bacteria and diseases. Always look for a source that seems to practice good tank hygiene.

Inspect the plant closely for snails and other visitors. Some of the tiniest water snails, no more than a couple of millimeters long, are rapid breeders. Unless you have loaches or other fish that will snack on them, they'll quickly take over your tank. You may quarantine a new plant outside your tank for a few days, to see if any snails appear.

Most aquarium plants prefer to live entirely submerged, so don't let them dry out. If your tank is not quite ready or if you want to grow more of your plants than will fit in a tank, use a bucket or bin of water.

Anchor the plants. Depending on the plant, this may be mostly an aesthetic matter, to keep them from bobbing around loose. For mosses, consider tying them loosely with string to a rock until they become established.

In general, do not bury the rhizomes, which usually are thicker and greener than roots or stem, in gravel, as burying them can cause the whole plant to quickly die, also try not to bury the crown just above the roots on other plants that need to be in the substrate .

LED Aquarium lights. Aquarium plants, like any others, require light for photosynthesis. Check the light requirements of the plants you are choosing, many require high amounts of added light. Low light plants will do well if your tank has plenty of light from windows. Otherwise, plan to light your tank with a led aquarium light for tank.

Add fish. While not strictly required, fish waste will help to nourish the plants. The plants, in turn, will keep the water conditions better for the fish by absorbing carbon dioxide and releasing oxygen during the daytime, at night the plants of course give off CO2. Some plants are good at removing ammonia or nitrites. If you don't have fish already, wait a week after adding the plants before you introduce them to the lush environment you're creating.

Change the water periodically. Plants do not need water changes the same way that fish do, but it is still a good idea to change the plant water when changing your fish water. Do not siphon in your plant bed, as you may kill and injure them. Run your siphon over the top of the soil in which the plants are planted, and make sure you don't damage them.

Remove algae. Algae growing on tank walls or on plant leaves competes with plants for light. You can remove algae manually by scrubbing or scraping the walls of your tank weekly when changing the water and rubbing the plant's leaves gently between your fingers. The far easier method, though, is to let your tank's inhabitants do the job for you. Shrimp and several catfish eagerly feed on algae and can help to keep your tank far cleaner with little or no effort on your part.

Divide or prune the plants if they outgrow your tank. Depending on your tank and your plants, you may find you have too much plant soon. Choosing slow-growing plants can help keep them small, but it can also mean having less plant and waiting longer for your plants to fill out. Find the right balance for your tank. more information about aquarium tank please visit: www.ledgrowlight.co.nz

Marijuana users have always sought legal loopholes in countries where it is illegal to own or smoke it. Many people choose to buy marijuana seeds (which is legal in many places), then grow and smoke their own (which is not!) But every marijuana smoker has probably dreamed at one point or another of living in a country where marijuana is legal - or at least where the "rules" concerning possession are so lax that it is effectively legal.

So, if living in a country where marijuana possession isn't punished by the law sounds like heaven, here are five places you should consider emigrating!

Australia
Before you go booking a one way ticket to Sydney, make sure you do your research. Different regions have different rules, but Western Australia, Southern Australia, Tasmania, Victoria and Queensland have all decriminalised marijuana to a certain degree. In Tasmania, Victoria and Queensland, police have taken to "ticketing" those caught with less than 50 grams of marijuana rather than arresting them, and Western and Southern Australia have instituted on the spot fines for minor possession rather than official warnings or arrests.

Argentina
After a recent court debate about whether or not to punish those who buy and grow marijuana, Argentina has effectively made marijuana legal if it is in small quantities for personal use. A leading judge in Argentina even decided that it was "unconstitutional" to legislate against marijuana possession! Those who buy marijuana seeds and grow their own are also leniently treated, so long as they are growing a small number of plants. The country is also notably supportive of several medical marijuana programs.

Colombia
Colombia, has had relaxed laws concerning drug possession for over ten years. Possession of less than 20 grams of marijuana, one gram of cocaine and one gram of heroin is not considered to be illegal, although things may change - recent conservative governments have considered repealing this law to combat Colombia's drug culture.

Nepal
Unlike the other countries on this list, Nepal doesn't have an actual decriminalisation policy towards marijuana - it's rather that the laws they have are hardly ever enforced! Marijuana used to be legal in Nepal, making it a hippy Mecca in the 1960's and early 70's. It has been illegal since 1973 - not that you'd notice. Marijuana is widely available and used, especially by Nepalese holy men. Note that smuggling and growing are punished, but possession and personal use rarely are - if the police catch you smoking they will stop you, but only to collect a small bribe!

Belgium
Since 2003, the Belgian government has made the possession and use of marijuana legal under the following conditions:
The amount possessed is 5 grams or less
You are over 18
You do not smoke in the presence of minors
You do not smoke in public
You can buy marijuana seeds and grow them in Belgium without penalty - however, you are only allowed to own one female plant. The purchase and sale of marijuana is still illegal, but most Belgians simply get their marijuana in Holland.

You’ve got lights, plants, nutrients, and everything you need to grow. You set up your grow tent, set your plants in place, and start hanging your lights. But before you switch those lights on, are you sure you know how high you need to hang them above your plants?
Hanging your lights too low can burn them, but hanging them too high can leave them stretched and weak. Some lights need to be far away from plants so you don’t burn them, but some lights are too weak to hang more than 10 inches away- so what do you do?
The trick is to hang your lights right in that sweet spot of effectiveness and safety. The distance of your lights to your plants is all about getting your plants the power they need to turn nutrients in to food for growth. So before we start talking numbers, let’s talk about the idea behind hanging your grow lights:

Fluorescent Grow Lights
Fluorescent grow lights are a nice, easy blend of energy and spectrum output. They’re low in both, but still effective enough to grow nearly any plant. But to do so, you’ll need to hang them pretty close.

What makes hanging fluorescent lights so tricky is that not all of them are the same. For instance, 35w CFL bulbs can generate some decent heat over an extended period of time because of their compact size, whereas a longer 54w 2ft T5 grow light won’t generate lots of heat because it can dissipate it along its tube. Not only that, but the more bulbs you use the more heat you’ll generate, which is dangerous if it’s hung too close to the plants.

Fluorescents aren’t known for kicking off lots of heat, but they will generate some so you’ll need to watch your plants carefully for signs of burning or bleaching. Depending on the wattage and size of the light, as well as how many bulbs are in the light, you’ll want to start off hanging them around an inch away from your plants. If your canopy feels hot move the light up another inch, and further if the canopy is still too hot.

LED Grow Lights
So is the heat these lights give off the reason they can’t be hung so close? Yes and no. Yes, because they’ll burn your plants with intense heat. No, because even if you eliminate heat you still need to worry about light temperature.

Simply put, what makes a light a “cool” blue light, or a “warm” red light, is the temperature of the light’s spectrum(s). HID’s give off good light temps, but LED’s are much more focused on spectrum output than energy generation, so you actually need to hang them higher above your plants than HID’s to avoid light bleaching. Light bleaching can be just as bad for your plants as over heating and will result in an underwhelming crop.

LED’s don’t generate lots of heat, but you’d be surprised by how high you have to hang them above you plants. For LED lights used to grow little patches of wheat grass, herbs, and spices (15w-90w) you’ll want to go at least 15″ away from your plants. For higher wattage lights it’s even further.

(240-400w) 16-30” away from plants
(450-550w) 20-30” away from plants
(600-850w) 24-26 away from plants
(900w+) 26-42” away from plants

HID Grow Lights
If you’re using HID grow lights you know that they generate a lot of heat, so hanging them close to your plants isn’t an option. On the opposite end, your plants will be flimsy and can even start to stretch too much if they’re looking for good light. Your plants spend more time trying to grow branches and not leaves and flowering sites when lights are far away.

That’s why when it comes to HID lighting, it’s best to keep them at least 12″ (30cm) away from your plants at all times. The stronger the light, the further you’ll need to hang it, so if you have a 1000w you may want to hang it at least 15″ (38cm) away. Depending on the strength of your light, you won’t want to go higher than 30 inches (76cm) above your plants. Smaller sized lights like 400w’s can only be around 20″ (~51cm) away from the plants, and medium sized 600w’s can be around 25″ (64cm) above the plants without losing vitality.

HID’s need to be hung above your plants at a good height because of the heat they generate, so if you’re using HID’s it’s important to have a tall growing space:

(400w) 12″-19″ away from plants
(600w) 14″-25″ away from plants
(1000w) 16-31″ away from plants

Buy led grow lights for indoor growing plants.

Given below is a list of few indoor plants which can be grown easily and do not require much care.

1. Jade plant (Crassula argentea) – This indoor plant has very thick leaves and looks like a small tree. This plant grows well in presence of light so it would be beneficial to keep them in rooms with windows facing outside. This type of plant has very good growth so you should always take big pot for planting it.

2. Devil's Ivy or Pothos (Scindapsus or Epipremnum) – This is a cascading vine plant and its beautiful shaped leaves have dark green color. It looks awesome when you put them in hanging baskets. This type of plant does not require much light and can be grown in dark room which does not have outside facing windows but it acquires good growth if you keep small grow light bulb in grow room.

3. Mother-in-law's tongue/Snake plant/Bird's-nest plant (Sansevieria) – The Mother-in-law's tongue and Snake plant has many varieties. Basically these plants are tall in compare to Bird's-nest plant. These plants can be grown very well in harsh extreme environmental conditions too. There is no need to repot this plant as it grows well in one pot. If the pot which has been used is very small or if the roots of the plant start coming out of the pot then only you should repot it.


4. Spider Plant (Chlorophytum comosum) - Whatever amount of light would be available to this plant, it would have good growth. Growing new spider plant is very easy, as main plant allows its miniature plants to grow on long hanging down stems. Spider plants roots can do well in small pots too, so no need to repot it. It looks beautiful if you grow them in hanging baskets.

5. Parlor palm (Chamaedorea elegans) – This plant is an exception to Palm tree; it does not require much sun light as all other palm tree requires. When grown indoor this plant can do well in low light and does not require much water. This plant can be grown to several feet height.

6. Rubber plant or Rubber tree (Ficus elastica) – Hobbyist growers love rubber plants because without taking much care rubber plants can be grown big in size with exceptional looks. This type of plants require good sun light so it's better to grow them in room with a window or you should provide a skylight to them for at least two hours a day.

7. Christmas cactus (Zygocactus or Schlumbergera) – This plant is available in two types. The Easter cactus flowers and Christmas cactus flowers. The Easter cactus flowers are grown around Easter, and Christmas cactus flowers are grown in late autumn or early winter. In actual this plant is not from cactus family. It is originally from plant family named "succulents". It requires moderate amount of water and few hours' sunlight or artificial light for its good growth.

8. Dragon tree (Dracaena Marginata) – Dragon trees are found in many varieties. Few varieties can be grown very easily than others. These plants need very good amount of light and water. These plants can be grown four feet tall.

Always select healthy and properly grown plants while buying them, for your hydroponic or indoor gardening is of utmost importance.

Its 2010, there are only a few lighting types you should consider. If you plan to keep only fish, you can be fine with the standard stock lighting which comes with your aquarium. If you plan a reef tank with living coral, then think of the following options.

Power Compact was the most popular lighting solution from 2000 to 2005. It provided a better upgrade from the normal output lighting. It is still used on many tanks today, but there are better and more cost effective choices.

V.H.O. or Very High Output lighting, don't even think of buying this type of light. The technology is completely outdated. Parts and replacement light bulbs are difficult to find.
Metal Halide Lighting is still a popular option. It provides an eye-catching shimmering effect that allows you to grow any type coral. The negative of Metal Halide lights is the amount of energy needed to run the fixture and the heat they produce. These lights are expensive to run more than ten hours per day, and you will have to buy a chiller to keep your aquarium cool.

T5 Lighting has become the top choice for saltwater aquarists. The bulbs are as intense as Metal Halide, but use half the energy. They also generate less heat and each bulb needs to be replaced once a year. Another major benefit is that you can control the color of the light spectrum because you have many bulbs that can be replaced to make the aquarium bluer or whiter.

Finally, you have the fast growing and famous Aquarium LED Lighting. This technology is still a little expensive for the average hobbyist. It provides the shimmer and power of metal halide without the heat, and the can control the color of bulbs like T5 Lighting. However in the next ten years, LED lighting will be the norm in the saltwater aquarium hobby.

The second type of HID lighting, High Pressure Sodium, is excellent for supplemental lighting in a greenhouse because the red light enhances flowering. The bulbs also last substantially longer than Metal Halides. Used as supplemental lighting, the orange-red light does not create leggy growth. It is interesting to note that plants do not appear as healthy under the reddish light as the blue because our eyes do not adjust well to the color. High Pressure Sodium bulbs have a long life; however, they should be replaced according to manufacturer's instructions. Bulbs continue to light beyond their useful life, however, the energy draw increases dramatically and the output lowers significantly.

Metal Halide and High Pressure Sodium lights generally do not use the same fixtures, however, some fixtures are convertible. With convertible fixtures, bulbs swap easily. A simple flip of a switch converts the fixture after changing the bulb. This is a good option for serious growers who want the benefits of compact growth, blooms and energy efficiency. The start up cost is not insignificant. However, the combination offers a tremendous amount of control in the greenhouse.

The newest type of grow lights use LED technology. One major advantage to the LED grow lights is the small size. LED grow lights are only a few inches in diameter and are easy to mount. In some greenhouses, LED grow light may be the only practical light option. Hanging most grow lights requires a strong greenhouse structure and a place to hang the lights. LED grow light weigh a fraction of other lights and are easy to configure where needed. According to LED manufacturers, LED grow light maximize blue and red light to provide and excellent balance for plants. They do not have much green-yellow light. Since humans see green-yellow light best LED grow lights appear dim to our eyes. And the most important advantage is that LED grow light is green technology which don't contain any harmful substance like HID or other traditional grow lights, and it can save 70-80% electricity bill than using HID lamp. This is newest technology used for plant growing now and becoming more and more popular.

While looking for the aquarium light, you should have an idea about what are your requirements. It is imperative that buying the lights fulfill all your needs. Apart from fulfilling the needs, the lights would also make the aquarium look attractive. Buying beautiful led aquarium lighting would add great beauty to the room in which it is placed. Most of these lights have got fabulous features would be very useful for the users. No matter where you keep the aquarium, lights will add a certain grace and beauty to the space. Not only the lights but the aquarium pump will also prove to be quite useful for maintain the aquarium in a better way.

Moreover, the aesthetics of the room will also be greatly enhanced by installing a beautiful aquarium light. However, it is recommended that you should search the market before going ahead with the purchase. It is better to assess your requirements and then go ahead with the purchase. All kinds of lights are available in the market. Over the last few years, mushrooming of online stores have added another dimension to shopping. Now, you shop online for lights sitting from your with a click of your mouse and the ordered product will be delivered at your doorstep. led aquarium lights new zealand.

All stores, online as well as on-site, offer a wide variety colors for your aquarium light. Many a light come with timers for dawn and dusk effects. What is more, the lights are kept cool by high powered internal fans. Many aquarium owners prefer LED moonlights for their fabulous effects. And, one can find these lights for aquariums of all sizes. You can find that numerous reputed brands offer these fantastic lights for fish tanks.

The lighting used for a reef aquarium is more intense than on any other type. The reason for this is that we are trying to simulate the sun as far as humanly possible. Reef aquarium lighting is normally more towards the blue end of the colour spectrum as we are trying to produce the lighting colours present at between 10m and 30m in water depth.

Colours are lost the greater the water depth is, the first loss is red. The reason we choose colours present at the depth given is that is the depth where the majority of corals are obtained.

The provision of lighting for a marine reef aquarium needs careful consideration. The depth of the aquarium, distance of the lights from the water, and the type of animals you wish to keep are questions you need to ask yourself.

In the aquarium corals receive energy from the light which is provided for them. The remainder of the energy required is from the corals themselves actively feeding. I will produce a post in the future which will cover various ways to feed your corals.
In the marine reef aquarium the aquarists has a responsibility to supply the light the animals would receive in the wild as far as possible. Obviously we cannot equal the sun itself, particularly its intensity, however we can produce the spectrum of LED aquarium light essentially required.

In the wild the light provision is simple. In basic terms light is provided for around 12 hours a day and a night period of around 12 hours. The light provided by the sun is very intense even when there is cloud cover. The amount of lighting wattage we would need to provide the aquarium to even come close to this sun power would be enormous. In terms of cost and physically fitting the lights it is clearly of no use to an aquarist. buy led aquarium lighting in New Zealand, you can visit: www.ledgrowlight.co.nz

Grow tent kits take all the hassle out of getting an indoor grow tent set up for the first time.  All of the pieces and parts that you will need for the indoor grow tent will be included in the grow tent kits, helping you to get organized and off on the right foot immediately.  Set up of the indoor grow tent has also been taken into consideration by the manufacturers; several of these indoor grow closets can be set up in as little as thirty minutes.  

As you begin your search for the perfect grow tent, you will want to decide if you want to garden in soil, or if you would prefer to try hydroponic gardening, which is a soilless means of growing excellent fruits, flowers and vegetables.  If you live at the top of an apartment building, for example, it can be difficult getting potting soil all the way up to where you would like to garden, so it may be much easier to get a hydro grow tent in this case.  You simply put your hydroponic growing system inside your hydro grow tent, add a light and a small exhaust fan and filter, and you are well on your way to growing the plants you like in a perfect, climate-controlled setting provided by indoor grow closets.  

While tents are made out of soft materials with reflective inner sides, which help to improve the plants' exposure to the light inside, a grow closet, which is often used as another name for the tent, can actually have stiff sides, rather like a large box.  The inside of the closet is also often coated with shiny material to improve the light saturation inside the box.  Bright light is important to plant growth, and all indoor grow lights in some way attempt to replicate natural sunlight that the plants would be exposed to if grown outdoors.

First of all, an important difference to take into account is that led grow lights have the ability to emit light belonging to different bands of the spectrum, according to very specific needs for a plant's maximum growth. Other products, such as fluorescent and high energy discharge lamps and incandescent light bulbs don't include this outstanding feature. Fact is plants contain a molecule called chlorophyll which allows them to produce their own nutrients and minerals through a process called photosynthesis, which at the same time lets them  Plants can only absorb light from certain bands of the spectrum, meaning that the rest of the light is useless to them. Thus, providing plants with the specific type of light they need is essential for successful plant growth.

In addition, indoor LED grow lights are also remarkable at preserving energy. While other light-emitting products waste a lot of energy and eject lots of heat that do a lot of harm to the environment, LED grow lights manage to consume a much smaller portion of energy and also eject less heat, allowing for a greener atmosphere. As many people have said, helping starts at home!

Another fact to take into account is that they are much smaller than older products, so they can be considered portable tools as they are also considerably lighter. And, they come with batteries that last much longer than normal, minimizing costs even more.

Overall, LED grow lights offer a much lower cost than other products, since they consume substantially less energy and come with long-lasting batteries. Moreover, they are very practical, they allow for excellent indoor plant growing, and they also let the user configure the specific spectrum of the light they want to emit for maximum performance and plant growth. What else do you need for outstanding indoor plant growing? LED grow lights certainly are the right way to go! buy led grow lights in New Zealand, please visit: www.ledgrowlight.co.nz

Aquarium gives a very classy look to the room in which it is placed. Why so? Because the beautiful fishes swimming across the aquarium, the background of the aquarium and the small aquatic plants which are placed inside the aquarium. All of these make the aquarium look just superb and attractive. The most vital factor which enhances the beauty of the aquarium is the lightning which brightens up the aquarium and makes it look loud and pretty. Several kinds of lights are available, but the best one preferred are the LED aquarium lights which are the best suited lights for the aquarium and of course because of the several good reasons.

LED aquarium lights make the aquarium looks beautiful and have many advantages over other lights as well. These lights reduce the cost of lightning, consumes less energy as compared to other lights and the heat generated from these lights is also less as compared to the normal ones. Moreover the biggest advantage it has over the normal lights is that the energy from these Aquarium LED lights is beneficial for the growth of the aquatic plants in the aquarium, which gives it one more reason to over power the normal lights.

When we place an aquarium, the lightning is continuous, and then only the aquarium will look like one and would enhance the beauty of our home. Since the lightning has to be 24/7, so we need such lights which would consume less energy and which would not land up paying heaps of bills for this. So, these lights are good to use in many ways and is moreover healthy for the aquatic plants inside the aquarium. These are available in several price ranges and are affordable; people can go for these without any hassles. led aquarium lighting nz

As a controlled environment, indoor grow rooms offer many advantages over outdoor alternatives. However, without adequate ventilation, the plants may consume resources, like oxygen and carbon dioxide, faster than they can be replenished. Adequate gas exchange is necessary for optimal plant growth. Ventilation in indoor grow rooms is vital for maintaining an optimal temperature for the plants. Advanced indoor grow rooms even include air conditioning to keep running temperatures down, as well as CO2 to boost the plant's growth rate.

The plants in indoor grow rooms can be grown in soil, or without, via other means such as Hydroponics and Aeroponics. Not only is growing in a soilless medium more cost effective, one also gets a much higher yield, as well as faster fruit maturation.  There will be no weeding out and no bugs to contend with. Soilless mixes usually carry 0% nutrients so the gardener can utilize the perfect combination of nutrients for the crop. Vermiculite, Perlite, Coconut husk and Rockwool are the most popular media for indoor grow rooms cultivation.

The three most common varieties of lighting for indoor grow rooms are HID - High-intensity discharge lamps (the most prevalent for this application being: high pressure sodium for flowering and metal halide for growing), compact fluorescent lamps, and traditional Fluorescent lamps. Incandescent and halogen lamps are not suitable for indoor grow rooms as they generate excessive heat, with a low lumen to watt ratio. LED lights are becoming more popular for indoor grow rooms due to their low energy requirements and low heat output. Recent advances such as 165 watt LED grow light have entered the LED grow light market and are proving to be highly efficient as a substitute for sunlight for growing plants. 
When choosing the size of the indoor grow rooms you intend to purchase you should take into account the number and the estimated size of the plants you will be growing. A 100*100*200cm grow tent is suitable for 8-9 plants, provided they will grow to full size. Indoor grow rooms with less than two ventilation flaps, should be supplied with ventilation "socks" which are easily installed and would ensure the tent was absolutely light proof. While deciding which tent to choose, note that a carbon filter and a light unit will weigh about 15 kg, so the tent should be rated to sustain such weight. However, modern indoor grow rooms are capable of safely bearing about 30 kg.

The variety of complete indoor grow rooms, ready to set up and start growing in immediately are plentiful. Large and small, they are all designed to be as efficient as possible. Your investment will pay off in no time both in better health and cost saving on groceries.  If you have a dark corner anywhere in your house or have space in your basement,  indoor grow rooms will provide you with hours of nourishing enjoyment and pleasure.

Aquarium LEDs

While any LED lights can be used to help illuminate an aquarium, the typical LEDs are useless in promoting plant growth. The most common types of LEDs simply offer a supplemental form of lighting. Lights designed for aquariums provide both illumination and support the ecosystem, primarily by encouraging healthy aquatic plant growth. To perform the latter function, special LED aquarium lights that are much more powerful are necessary.

Aquarium LED Cost

The primary drawback to LED lighting in aquariums is the cost involved. To get lights that accomplish all the functions needed, the cost is routinely in the hundreds of dollars for small aquariums and over $1,000 for large ones as of 2011. While you may often see LED lights advertised for aquariums at under $100, these are simply supplemental light LEDs that will provide illumination but cannot replace the function of fluorescent lights in supporting the ecosystem. Costs are falling rapidly as more enthusiasts use LEDs, but they are not competitive with fluorescent lights as of 2011.

Heat Benefits

Aquarium LED lighting avoids creating energy that is wasted as heat. It also eliminates the need for cooling fans to dissipate the heat fluorescent lights generate. This will allow you to use standard heaters to control the temperature of your tank without fear of damaging the tank through the failure of a lighting fan or any other light malfunction.

LED Precision

The light emitted from a proper aquarium LED source can be manipulated to provide precisely the wavelengths of light that are most beneficial to the type of aquatic plants you keep in your aquarium. You can also manipulate LEDs to simulate moonlight, to provide an almost natural environment for your tank.

LED Grow Lights

LED Grow Lights are comprised of multiple low-wattage diodes (normally 1W-5W) that work together to create the complex spectral varieties that marijuana requires to grow properly. LED Grow Lights work almost like a puzzle, with each LED wavelength playing a specific role in determining how the plant will grow and produce. By fine-tuning the wavelengths and ratios of a LED Grow Light properly, up to 100% of the light being produced can be efficiently absorbed marijuana plants. This gives LED Grow Lights a huge efficiency advantage over HID Grow Lights, allowing the end user to consume far less energy to achieve similar or better results.

LED Grow Lights provide many additional benefits that HID lights do not. LED Grow lights contain no mercury or harmful elements, and as such can be fully-recycled. HID bulbs on the other hand, must be changed at least once per year at a cost of $100-$200! LED Grow Lights also consume about 60-70% less energy, putting money back into your pocket with each power bill. LED Grow Lights also operate up to 600 degrees colder than HID Grow Lights, virtually eliminating the need for ventilation and A/C equipment.

It works like this; If the authorities suspect someone is cultivating marijuana, they set up surveillance of the home or building and use an Infrared camera to measure the amount of heat radiating off the structure. They then compare the targeted structure to surrounding buildings or homes to gauge what they think should be the normal amount of heat emitted from a particular structure.

In some parts of Europe, the authorities don't even wait for a lead from an informant to give them the heads up, on a possible marijuana grow operation. They simply take to the air and use their high-tech surveillance camera and scan the roofs and walls of homes in residential areas and buildings. If a home is identified as a possible marijuana grow operation because of the heat radiating off the structure, that home or building becomes the target of further investigation and possibly a raid.

Using HID lamp will emit too much heat that could be inspected by infrared camera. Now, LED grow lights could deal with very well because it is cool light source which make authorities can not find what you do inside. So more and more growers are replacing of their HID lamp by LED grow light. For more information about LED grow light, please visit www.ledgrowlight.co.nz
