The NFT (Nutrient Film Technique) was once commonly used among commercial and smaller scale hobbyist or amateur hydroponic growers. Its use has diminished among commercial growers recently primarily because new hydroponic techniques exist today that are better suited to large-scale farming.

Amateur hydroponic growers however still use NFT often. It’s not that expensive, it’s very simple to use, and it can be easily adapted to accommodate many different plant types.

The NFT is one sort of solution culture in hydroponics. Solution culture hydroponics involves the growing of plants without growth medium and without soil. 世博 NFT  Many hydroponics growers genuinely believe that solution cultures are the only real true type of hydroponics. They say that after growers add solid growth mediums, they’re adding nutrients to the plants in the same way soil does. NFT on one other hand, treats the plants only with nutrient solutions prepared by the growers and sent to the plants root system via water.

NFT Hydroponics Systems work by generating a constant water flow at the plants’ root systems which are suspended in a tub. The slow moving water solution is disseminate across a flat work surface at a level of approximately 1 to 3 inches. This shallow solution depth is constantly maintained to produce a nutrient film over the plant roots.

When setting up your own personal NFT system you will be needing a shallow, flat-bottomed tub and a submersion pump which will keep the water flowing over the plant roots. The plants must certanly be placed close together in order to enable the nutrients to more readily cling to the roots. The submersion pump will constantly recycle the water back to the system. And because the water has been constantly recycled, you should closely monitor the nutrient levels in the water.

The NFT technique comes with a couple of potential drawbacks which have to be addressed. As an example the nutrients necessary for the plants may cause harm to the submersion pump. If the submersion pump fails, or when there is an electrical failure, your plants will not be getting the nutrients they have to survive. A relatively short disruption in the pump can lead to perform failure in your plants.
