I use a setup alot like stinkbuds Green grow tote (without posts) using a roughneck totes and pumps and sprayers and 2" net pots. Well I was trying to figure out a really cheap way to have some plants off on the side alone in hydro. I came up with DWC using a bucket and a lid and I'll cut a hole in the top for my 2" net pots (have neoprene inserts too) and just filling the bucket up to the roots and putting a bubble stone in it.. I figure this way I don't need to waste money on any grow medium. Should work right? I don't see why not.
