I'm gonna be using 100% growstone in hempy format for my next run in about a month. Running 3:1 perlite/vermiculite now, but I have a feeling the growstone is gonna outperform it easily.
@iampepe They look fantastic! Can almost smell em from here.
I bouught mine at the local grow store - $25-30ish bucks for 1.5cubic feet, and it's more reusable than perlite or vermiculite. Doesn't turn to powder, either.
