Thanks begetting.
I'm starting to think it will be ok.
Especialy if I put the rockwool on a bed of expanded clay, and don't let the water level rise past the base of the rockwool.
Although it will soak up to the top, it may not drench it.
Do u think it would work with rockwool intended for insulation of ceilings?
I got these peices rather cheap from a local hydro shop, and I don't trust them to be specifically grow wool.
They certainly aren't grow dam.
Maybe I should go see the shop manager, and just ask him staight out.
Although, they do claim to be grow wool.
do U think it'd make a lot of difference?
