Since hydroponics saves water drastically and reduces evaporation, it means that it is a perfect way to grow sustainable, crunchy, healthy lettuce. Hydroponic Lettuce Nutrient Requirements. CropKing recommends using a nutrient film technique (NFT) system for lettuce and leafy greens production. In this type of system, a thin film of nutrient solution flows through the channels and over the roots, which provides constant access to both nutrient rich water and oxygen for the roots, said horticulturist Jim Brown. This not only lowers water bills, but allows water to be used much more sustainably. Posted in E. coli,Our Blog,Outbreaks & Recalls on May 1, 2018.
