It may be that I had a bad batch---if 200lbs is considered just a batch---but the hyponex that I bought gave me nothing but grief. It needed tons of sand, perlite and lots of working to salvage it. Still I'd never use it again. That's just my opinion. I'm using B'Cuzz coco now. But thats a whole 'nother ball of wax, so to speak.

Anything but Hyponex for me---anything.
