Well I bought some hydroton and transplanted the seedlings that has the curled leaves. I didn't have any of the small bagged RW so I cut up all my 1 inch clone size rw cubes for now. It looks snug and happy, lets hope those roots will shoot down now. Main thing is the RW is cut very small, so there are lots of places in the cracks that oxygen will stay in.

As for the rest, I added a layer of hydroton to the tray, and filled it up with my solution. This way any roots coming down from the rw blocks will have water to drink from, while keeping the rw cubes relatively dry.

feedback?
