The NFT (Nutrient Film Technique) technology is one of the hydroponic methods used for cultivating plants, including lettuce. In this system, the plant roots are suspended in a continuous flow of nutrient solution, which is pumped through an inclined channel or a thin tray. This thin flow of nutrient solution allows the roots to receive essential nutrients such as nitrogen, phosphorus, and potassium, along with other necessary substances for healthy plant growth. The system utilizes a minimal amount of water because the water and nutrients are constantly recirculated within the system, thus reducing waste and the need for irrigation. By precisely monitoring and adjusting the composition of the nutrient solution, growers can ensure that plants receive the optimal amount of nutrients to grow healthily and produce quality yields.
