Starting Your NFT Hydroponic Technique

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 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 easy to use, and it could be easily adapted to match a variety of plant types.

The NFT is one kind 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 only real true kind of hydroponics. They say that whenever growers add solid growth mediums, they are adding nutrients to the plants in the exact same way soil does. NFT on another hand, treats the plants only with nutrient solutions prepared by the growers and delivered 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 disseminate across a flat surface at a degree of approximately 1 to 3 inches. This shallow solution depth is continually maintained to create a nutrient film within the plant roots.

When establishing your own NFT system you will need a shallow, flat-bottomed tub and a submersion pump which keeps the water flowing within 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 to the system. And since the water is being constantly recycled, you will have to closely monitor the nutrient levels in the water.

The NFT technique does have a few potential drawbacks which have to be addressed. Including the nutrients essential for the plants could cause damage 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 comparatively short disruption in the pump can lead to perform failure in your plants.
