NFT is often referred to as ‘pure hydroponics’ because virtually no growing medium is used and roots benefit from unrestricted access to oxygen.
When using NFT systems, nutrient solution is constantly pumped up from the reservoir to the roots in the planting channel, any nutrient solution not taken up by the plant flows back into the reservoir ready to be passed over the roots again.
The only growing medium used is whatever the plants were started in, plus small amount of spreader mat to help spread the nutrient solution over the channel surface. While rockwool blocks are an ideal starting starting medium and the preferred choice of many growers, in fact compost can be used so long as the plants are well rooted and the compost holds together when removed from the pot. Plants MUST be removed from the pot or the outer sleeve removed from the rockwool block when using NFT systems for effective root development, failing to do so is the main cause of NFT failure along with not having sufficient root mass before transplanting.
Constantly supplying nutrient solution directly to the roots combined with an unlimited supply of oxygen means plants grow faster, are healthier and typically produce 3 x more yield than plants grown in pots and hand watered.
Well-rooted plants sit on the MultiDuct tray and nutrient solution is constantly pumped from the tank over the bare roots on the channels above. Unused nutrient flows down the tray and back into the tank.
Plants will draw in water & nutrients themselves whenever they need it. They are never underfed or over-watered and there is no build-up of salts in the root zone.
The plants are added to the grow system without the need for much media, greatly reducing the chances of diseases being transmitted as they have nowhere to hide in wait.
