Where to buy BIG bags of coarse perlite in twin cities?
I'm looking for a cheap source of coarse perlite. The big 3-4 cubic foot bags are the way to go, but I don't see them very often. I remember buying some at Lyndale Garden Center years ago, but of course that's gone now. Midwest Hydroponics carries 4 cubic foot bags, but only in medium (too many fines) and chunky (way too big). I haven't called around yet, but I thought I'd check and see if anyone knew a good source off the top of their head.
