roflmao!!! You don't ever remove seedling from rockwool...i.e. You plant and root in rockwool, then you take rooted rockwool plug/plant and place in netpot with hydroton...

as long as you pump fresh solution over the rockwool at consistant intervals your off times will provide enough oxygen to get to the rootzone.

sorry, but your post kills me...How did you get the seedlings out of the rockwool without killing the poor 'lil things?
