NFT slope

Hi there...

I was wondering what slope is best for a sqaure channel NFT system...

I read somewhere that no less that 80:1 is correct. Iam curently running it at ~40:1.

I think it may be running a little fast but its hard to tell as I just started growing.

It's outside, the weather in Korea is warm now and most greenhouses here are selling seedlings.

Iam growing a variety of different plants, 1 cucumber, 1 melon, 3 tomatoes, 26 snow peas, 3 chile peppers, some kale, some spinache, some watercress and a strawberry.

Its a long system divided in two along the railing of my balcony. One section is about 6.5 meters and the other, 4 meters. There are 24 baskets in total.

Re: NFT slope

I have always heard between 50:1 and 75:1 is optimal, but over 100:1 is not suitable at all.

Given the length of your sections, I would say that you should stay around the 40:1 - 50:1 range, and you should be fine.

If you are interested, you should look into the "bible" of NFT called "ABC's of NFT", by Dr. Alan Cooper.

Do you know some hydroponic suppliers in Korea, maybe in Busan? Or Korean websites for hydro?
