Foam Floating Model

The deep flow Technique is a variant of the NFT technique, which is also called nutrient flow technique. Instead of the thin nutrient film, the plants are surrounded by an approximately 4 cm high nutrient solution. The system is working circularly. The deep flow technique makes this type of hydroponic system safer, as the roots are still supplied even if the pump fails.

Foam floating model is one type of DFT system in flat way. It is also commonly used for plant propagation or herb leafy vegetable cultivation.
