I was at the Home Depot tonight and picked up 4 bags of stove chow to try out as I will be needing to get another ton yet this year when my Hamers run out. On the bag it says 100% White Wood. Does this mean white pine, white oak or what? I need to know if I should set my stove for Hardwoods or softwoods. I paid $3.94 a bag, pretty decent price.
