The NFT (Nutrient Film Technique) used to be commonly used among commercial and smaller scale hobbyist or amateur hydroponic growers. Its use has diminished among commercial growers recently mainly because new hydroponic techniques exist today which are better worthy of large-scale farming.

Amateur hydroponic growers however still use NFT often. It’s not too expensive, it’s very easy to use, and it can be easily adapted to suit numerous 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 think that solution cultures are the sole true form of hydroponics. They say that when growers add solid growth mediums, they’re adding nutrients to the plants in exactly 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 continuing water flow at the plants’ root systems which are suspended in a tub. The slow moving water solution is spread out across a flat surface at a level of approximately 1 to 3 inches. This shallow solution depth is continually maintained to create a nutrient film on the plant roots.

When establishing your personal NFT system you will need a shallow, flat-bottomed tub and a submersion pump which will keep the water flowing on the plant roots. The plants should 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 into the system. And since the water has been constantly recycled, you will need to closely monitor the nutrient levels in the water.

The NFT technique has several potential drawbacks which have to be addressed. Including the nutrients necessary for the plants can cause harm to the submersion pump. If the submersion pump fails, or if there is a power failure, your plants will not be getting the nutrients they have to survive. A somewhat short disruption in the pump can lead to accomplish failure in your plants.
