yeah.. plus that was stupid what I said.. re-using shit is cool.. less waste is always better...lol, not concerned w/ the cost just didn't want to have a mountain of old rockwool to dispose of.
same way you got rid of your mother in law?Rockwool is easy to get rid of. Shred it and break up how its trashed but not in your trash is best. tear it up and dump it in a dumpster somewhere.let it dry after yanking the roots best as possible and then run it over with the mover with mulch blade going then sprinkle it anywhere.You can simply bury it someplace.
