A frame-NFT hydroponics system

Nutrient Film Technique, abbreviated as NFT. A simple energy-saving soilless cultivation technique. Cultivate the crop roots in a thin layer of nutrient solution. By using a water pump to continuously or intermittently circulate the nutrient solution from the storage tank to the crop roots planted on the cultivation bed, a portion of the roots are immersed in the nutrient solution while the remaining roots are exposed to the air. This effectively solves the contradiction between root water absorption and oxygen absorption. Compared to other hydroponic methods, it is more energy-efficient, material efficient, and cost-effective. Widely used in soilless cultivation of leafy vegetables.
