There are two main types of hydroponic systems that can be used in commercial production of modern greenhouses. One is DWC (Deep water culture) and the other is NFT (Nutrient Film Technique). NFT is a hydroponic technique in which the roots of plants grow in a plastic film tank or a fixed channel, through which the nutrient solution circulates continuously , So as to provide the necessary nutrients and moisture to the plants.

To build the skeleton, it is recommended to use stable and rust-resistant materials. The length of the planting trough should not exceed 4.5 meters. There needs to be a slope difference between the head and tail of the planting trough, which is generally 2%-3%. The planting trough shown in the figure below is 3 meters long, the tail is about 5 cm lower than the head, and the slope is 1.67%
