Has anyone seen this new chunky perlite fox farm has?Its in a big 4 cu. ft. bag for only $20.You can even use it in net pots.I think its better than hydroton.I got it to mix in with my soil.There are no sharp eadges and the stuff is lots bigger than norm. plus i was paying $3 a bag at walmart for these little bags of little perlite.This is alot better deal.And mixed with peat at 60% peat to 40% chunky perlite and a little lime makes a great light mix.
