The NFT (Nutrient Film Technique) used to be very popular among commercial and smaller scale amateur or amateur hydroponic saying. Its use has receeded among commercial upcoming nft drops saying in recent years mainly because new hydroponic techniques exist today that are better fitted to large-scale farming.
Amateur hydroponic saying however still use NFT often. It’s not that expensive, it’s very easy to use, and it can be easily taken to suit many different 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. Many hydroponics saying believe that solution cultures are the only true form of hydroponics. They say anytime saying add solid growth mediums, they are adding nutrients to the plants such as soil does. NFT on the other hand, treats the plants only with fertilizing solutions prepared by the saying and delivered to the plants root system via water.
NFT Hydroponics Systems work by generating a constant 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 width. This cursory solution depth is constantly maintained to manufacture a fertilizing film over the plant roots.
When setting up your own NFT system you will need a cursory, flat-bottomed tub and a submersion pump which keeps the water flowing over 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 for cash the water back into the machine. And because the water is being constantly recycled, you will need to closely monitor the fertilizing levels in the water.
The NFT technique does have a few potential drawbacks which need to be addressed. As an example the nutrients necessary for the plants can cause damage to the submersion pump. If the submersion pump fails, or if there is an electrical failure, your plants will not be getting the nutrients they need to survive. A relatively short disruption in the pump can lead to complete failure in your plants.
