N.F.T. systems have a constant flow of nutrient solution. It was developed as a way of giving plants’ roots constant access to water, nutrients and the all-important oxygen! The nutrient solution is pumped into the growing tray (usually a tube) in a very shallow stream and flows over the roots of the plants, and then goes back into the reservoir. There’s little or no growing media used in NFT systems.
Anything can be grown with this technique – from leafy vegetables and herbs to bigger plants like tomatoes and cucumbers.
The main disadvantage ot the NFT is an eventual pump failures or power outages, because as no growing medium is used the roots dry out very rapidly when the flow of nutrient solution is interrupted.
