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 due to the fact new hydroponic techniques exist today that are better worthy of large-scale farming.
Amateur hydroponic growers however still use NFT often. It’s not that expensive, it’s very simple to use, and it could be easily adapted to suit 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 genuinely believe that solution cultures are the only real true form of hydroponics. They say that when growers add solid growth mediums, they’re adding nutrients to the plants in the exact same way soil does. NFT on the other hand, treats the plants only with nutrient solutions prepared by the growers and brought 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 working surface at a level of approximately 1 to 3 inches. This shallow solution depth is continually maintained to make a nutrient film over the plant roots.
When creating your personal NFT system you will need a shallow, flat-bottomed tub and a submersion pump which ensures you keep the water flowing over the plant roots. The plants must certanly 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 to the system. And since the water has been constantly recycled, you will have to closely monitor the nutrient levels in the water.
The NFT technique comes with several potential drawbacks which need to be addressed. For example the nutrients required for the plants can cause damage to the submersion pump. If the submersion pump fails, or if you have an electric failure, your plants will not be obtaining the nutrients they need to survive. A somewhat short disruption in the pump can lead to perform failure in your plants.
