The Nutrient Film Technique (NFT) is a hydroponic system that uses pumps to circulate a thin film of nutrient solution through shallow channels. The nutrient film forms in the bottom of the channel, which is how the system got its name. The nutrient film provides the plant roots with a consistent supply of nutrients and oxygen.

NFT BEGINNER TIPS

Keep the feed pump running NFT systems are designed to run 24 hours a day to keep roots wet.

If the pump is turned off, root tips can dry out, causing cell damage and dead root mass.

Ensure water is reaching the bottom of all roots each root cup must be positioned so that the roots of the plant can reach the nutrient film.

Keep the roots in the dark light can cause the roots of your plants to grow algae. The algae will warm up the roots too much and compete with the roots for oxygen.

Support the plants As the plants develop, stake, tie, or use other support. Don't plant too close together, as the roots can clog the channels.
