The nutrient film technique (NFT) is a hydroponic technique in which plants are recirculated from the bare roots of plants in a waterproof gutter, also known as channels, in very superficial water flow containing all the dissolved nutrients necessary for plant growth. The troughs are placed on the stands. Tables are made of profiles made of galvanized sheet metal.

NFT channels are 2-part and made of PVC material. The upper part slides out and the plant provides an easy discharge feature.

In the irrigation system, fertilizer water is fed into the canal by the main fertilizer water carrier pipes and spaghetti pipes by the road.

Drainage line: The water flowing from the channels is discharged into the drainage system pipe at the end of the channel. These waters are carried to the fertile water pool by means of the main drainage pipes.
