Planning The NFT Hydroponic Structure
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 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 simple to use, and it can be easily adapted to accommodate numerous 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 genuinely believe that solution cultures are the only true type of hydroponics. They say that when growers add solid growth mediums, they are adding nutrients to the plants in the same way soil does. NFT on the other 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 consistent 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 depth of approximately 1 to 3 inches. This shallow solution depth is continually maintained to make a nutrient film over the plant roots.
When setting up your personal NFT system you will need a shallow, flat-bottomed tub and a submersion pump which keeps the water flowing over the plant roots. The plants should be placed close together to be able to enable the nutrients to more readily cling to the roots. The submersion pump will constantly recycle the water back into the system. And as the water is being constantly recycled, you should closely monitor the nutrient levels in the water.
The NFT technique does have a couple of potential drawbacks which need to be addressed. As an example the nutrients necessary for the plants may cause injury to the submersion pump. If the submersion pump fails, or if there is an electrical failure, your plants won’t be having the nutrients they need to survive. A comparatively short disruption in the pump can lead to accomplish failure in your plants.
