NFT Hydroponic System
NFT hydroponic system
Nutrient Film Technique, or NFT, is a popular and versatile hydroponics system. It is similar to Ebb and Flow hydroponic system in that it uses a pump to deliver fertilized, aerated water to the grow tray and a drain pipe to recycle the unused nutrient solution. The difference is that in NFT the nutrient solution is continuously flowing over the roots. This is accomplished using gravity. The grow tray is placed at an angle to allow the water to flow down towards the drain pipe, and new solution is constantly being pumped into the high end of the tube. NFT is an active hydroponic system, meaning it relies on moving parts to work. Passive systems such as Wick Systems have no moving parts.
The nutrient solution flows in a thin film over the roots, ensuring that they are watered and fed but not completely soaked. .Nutrient Film Technique is an ideal hydroponic technique for vertical farming, where plants are stacked vertically as well as horizontally, making for almost unlimited amounts of crop space.
