Wouldn't it be easier to just soak the rockwool in conditioner and use it? ...or, you could use rapid rooters.

Trying to root directly in the clay pepples sounds like it would be wrought with problems.

PharmaCan Reviewed by PharmaCan on . rockwool ph problems Ive been reading so much about the ph problems with rockwool... is it possible to root the seedlings directly into clay pebbles? I know that it would be much harder to support the plant, and it would also risk light exposure to the roots probably... but does anyone do it? Rating: 5
