I have a homemade flood table with a center drain that doubles as the filler/drain. It's a 4x4x9"deep lined with epdm pond liner. I want to grow in 4" rockwool. I flooded a few cubes without plants in them and it takes a few days for them to dry out again. Is that how I judge when to flood again. I thought they would have to be flooded every few hours, but as I read on it's only if they were in clay pellets or some other medium that drains quickly
any suggestions and if anybody else is growing in rockwool alone on a flood table please show me some of your methods so I can get started, thanks
