I've heard that better garden stores carry K2SO4, but I haven't had any luck. Also, I was in Home Depot and they had a stump remover that was a white powder, but the ingredients wern't listed on the bottle. It's not Green Light, but it looked pretty simple. However, they're are lots of chemical supplies around, but I don't think they deal with small quanties. Got any ideas?
Thanks,
Creighton
