In my flood and drain I use 4" rockwool cubes and a Lowe's concrete mixing tub. I have it elevated towards the drain hole, which sites about a quarter inch above the bottom of the concrete mixing tub, therefore any water that gets pumped in will drain out except the 1/4" that can't reach the drain. It makes my rockwool sit in a puddle of water, which I know isn't a good thing. I was thinking about sitting a rack in there, but that wouldn't help much and it would make me have to flood higher.
Any suggestions?
