from what I hear it is basically the same convenience that rockwool is.. I actually saw a guy getting some at the hydro store a few months ago.. but tell me.. how is it superior over rockwool other than the environmental reasons? Have you compared the two? I use rockwool now.. and haven't been convinced to switch to coco.. does it retain moisture? I was just curious.. if, there were, in fact, actual advantage over rockwool...
