Small NFT vertical system

Gwen himself said:

I use a very minimal “slope” on the rolling trays I built out of fence posts and 2x4

It’s been years but I’d say 1/8th inch is a good differential.

I’ve ran that NFT plastic fence post set up, they can be finicky, water temps etc.

Do yourself a favor and buy a pond liner and throw it down under your grow.

Water will be spilled.

Happy Growing
