Indoor grow tent are quickly becoming very popular with people growing their own food.  Indoor grow rooms are a step up from the grow cabinet because you can product vastly more plant matter. If you have the room for one, you could feed a family of four with fresh produce almost all year round.

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.
