So I had a simple question. When starting to grow without soil, does the rockwool have it be TOUCHING the water or do I keep my water line below my pots?
Will the roots grow into the water or do I have to have the water line touching the bottom of the rockwool, please help, thanks.
Picture attached to show what I mean.
