Hydroponics is a technology for growing plants in nutrient solutions which is a combination of water and fertilizers.  Hydroponic gardening is done with or without the use of artificial medium such as sand, gravel, vermiculite, rockwool, peat, coir, sawdust to provide mechanical support for the plants.  Liquid hydroponic systems have no other supporting medium for the plant roots while aggregate systems have a solid medium of support.  Hydroponic systems that advantages of using hydroponic system in hydroponic gardening include high-density maximum crop yield, crop production where no suitable soil exists, a virtual indifference to ambient temperature and seasonality, more efficient use of water and fertilizers, minimal use of land area, suitability for mechanization, and disease or pest control.  The major advantage of hydroponic gardening compared to field grown produce is the isolation of the crop from the soil, which often has problems of diseases, pests, salinity, poor structure and/or drainage.

On the other hand, the principal disadvantages of hydroponics system, relative to conventional open-field agriculture, are the high costs of capital and energy inputs, and the high degree of management skills required for successful production.  Capital costs may be especially excessive if the structures are artificially heated and cooled.  This is why appropriate crops are limited to those with high economic value such as tomatoes MJ.

Away from all those disadvantages, hydroponic system is a technical reality.  Hydroponic gardening is a highly efficient production system which produces horticultural crops where field-grown fresh vegetables and ornamentals are unavailable for much of the year.  The development and use of controlled environment agriculture and hydroponics have enhanced the economic well being of many communities throughout the world.  Although there are some set backs with hydroponic gardening e used in hydroponic gardening are further categorized as open, where after the nutrient solution has been delivered to the plant roots, it is not reused; or closed where surplus solution is recovered, replenished, and recycled. The definition of hydroponics has been confined to liquid systems only, which blurs statistical data and leads to underestimation of the extent of the technology and its economic implications. All hydroponic systems that are being used in hydroponic gardening in temperate regions of the world are enclosed in greenhouse-type structures to provide temperature control, reduce evaporative water loss, and to reduce disease and pest infestations.

The principal but the benefits we can reap outweighs all the disadvantages. more about hydroponic information, please visit: www.ledgrowlight.co.nz
