I liked aspen at first, but now it is really irritating me. My snakes all seem to push it out of the way, and end up directly on the glass above the heating element. I don't want any burns so I plan on buying some bags of Cyp and going back to it. I always have trouble getting it in the off-gardening season, so I plan on stocking up and throwing some extra bags in the basement; how do you other aspen-users cope?
