What NFT Is

NFT flows a thin film of nutrient solution continuously down sloped channels; plant roots dangle into the film and absorb food and oxygen. No growing medium is needed at the roots.

The Setup

  • Sloped PVC or food-grade channels.
  • A reservoir with a pump on a timer.
  • Net pots holding plants at the channel top.
  • A return pipe back to the reservoir.

Pros and Cons

Pros: space-efficient, low medium cost, fast growth. Cons: a pump failure can kill plants within hours -- reliability matters.

Frequently Asked Questions

Q: Do I need growing medium?

A:

Just a little at the crown (rockwool or clay) to anchor the seedling.

Q: Is it hard to build?

A:

Moderate; the slope and pump are the key details.

Q: Best crops?

A:

Leafy greens and herbs; not fruiting plants.
