disrupt86 Reviewed by disrupt86 on . Reusing Perlite & Vermiculite?? Hey guys, Just cleaning up from my last grow and am curious. If the two materials hold no nutrients shouldn't i be able to reuse the medium as long as the salts are rinsed from it? A speedy reply would really be appreciated as im ready to go!! :) Thanks Rating: 5
