So adding both perlite and vermiculite is better than one or the other by itself? What brand of Perlite do you use? I am using miracle gro perlite and it seems to crumble easy. Maybe a different brand of perlite doesn't crumble as easy?
I don't even crumble Perlite and yes I use the same brand as you do. I never had a problem with it crumbling by-it-self it could of been a handling issue with the company you bought it from.
I have yet to find a brand without miracle grow fertilizer in it and it kills me because i grow organically. I do use both Perlite and Vermiculite together at about 1 cup each per 5 gallons of organic potting soil.
