Question about capillary action in seedling trays
Hi, I am attempting to bottom water my seedling trays in a NFT open gutter system, with the tray cells filled with peat moss. I originally placed the trays (w/ peat moss) in the NFT system to see if they would wick the water up over night but didn't have success.
My question is, do I need to soak the peat moss first to activate the capillary action? Any other suggestions? Thank you.
