I'm building a system similar to your hempy set up. I was going to put holes in the lids of 5 gal. buckets for 3 gal. pots , but instead of letting the roots get in the reservoir , I was going to use nylon rope to wick nutes from the reservoir. Seems like it would be efficient and easy , but I never hear any mention of wick systems.Have any of you kind sages ever tied it? It took me 2hrs. to get to post 19 , so I skipped to the end.If my Question is redundant , Im sorry , but I'd really like to know if I'm pissin in the wind with this wick idea.
