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 lately for the reason that new hydroponic techniques exist today which are better suitable for large-scale farming.
Amateur hydroponic growers however still use NFT often. It’s not too expensive, it’s very user friendly, and it could be easily adapted to accommodate many different plant types.
The NFT is one type 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 kind of hydroponics. They say that when 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 continuing water flow at the plants’ root systems which are suspended in a tub. The slow moving water solution is disseminate across a flat working surface at a depth of approximately 1 to 3 inches. This shallow solution depth is consistently maintained to produce a nutrient film within the plant roots.
When establishing your personal NFT system you will require a shallow, flat-bottomed tub and a submersion pump which will keep the water flowing within the plant roots. The plants must 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 in 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 a couple of potential drawbacks which have to be addressed. As an example the nutrients required for the plants may cause injury to the submersion pump. If the submersion pump fails, or when there is a power failure, your plants won’t be getting the nutrients they need to survive. A relatively short disruption in the pump can lead to accomplish failure in your plants.
