Double layer hydroponics system NFT gully
About the hydroponics :
Hydroponics is a subset of hydroculture, the method of growing plants without soil, Referred to as the NFT (nutrient film technique).Its principle is making a very thin layer of nutrient solution(0.5-1 cm), using mineral nutrient solutions in a water solvent.Terrestrial plants may be grown with only their roots exposed to the mineral solution, or the roots may be supported by an inert medium, such as perlite or gravel. The nutrients in hydroponics can come from an array of different sources; these can include but are not limited to byproduct from fish waste, duck manure, or normal nutrients.
