WHAT IS NFT:

Nutrient Film Technique, or NFT, is a versatile hydroponic system.
Anyone can learn to use with a bit of knowledge and know how, it’s not hard to learn.
Similar to an Ebb and Flow system which uses a pump to deliver fertilized water grow trays and a drain pipe to recycle the unused nutrient solution.
The difference is that in NFT the nutrient solution is continuously flowing over the roots, accomplished by using gravity.
The grow trays are placed at an angle to allow the water to flow down towards the drainpipe, with new solution constantly being pumped into the high end of the tube.

NUTRIENT IN NFT:

The nutrient solution flows in a thin film over the roots, ensuring that plates are watered and fed, however, not completely soaked.
The thin film ensures that the upper part of the root remains dry and in addition has access to oxygen in the air.
NFT works best if you choose plants that do not require a lot of support. With that in mind, lightweight, fast-growing plants that can be harvested quickly.
If the growing of plants such as tomatoes or squash is desired, make sure there are proper support systems in place such as trellises.
The roots are not suspended in a growing medium in this system, so they cannot handle supporting a lot of weight from a top-heavy plant.

CHANNELS:

NFT uses tubes or channels instead of flat trays for the grow tray.
This makes it easy to set at an angle, ensuring the nutrient solution flows directly to the roots without waste.
Most often DIY systems use a round tube or PVC pipe with holes drilled to fit the pots.
This has the advantage of being cheap and readily available to a home hobbyist.

GROWING:

Place seedlings directly into the holes of the PVC pipe or channel.
Or for greater stability plant in net pots and place the pots in the holes.
Growing mediums are not generally used with NFT, roots fall directly through the net pots and onto the film.
If a growing medium is used, use it sparingly making sure that the roots have plenty of room.
Whichever way you plant, always check and trim the roots often, this prevents overgrowth that may clog the system.
