What is NFT?
NFT stands for Nutrient Film Technique. These recirculating hydroponic systems consist of growing channels or trays over which the nutrient solution is constantly pumped across, creating a nutrient film into which the roots grow. Plants are often started in rockwool cubes and placed on the growing channels. The channels should be covered so the roots can extend out from the cubes forming a large root mat across the channel. The solution is recirculated from a main tank.
