Hey, new member and new snake owner here. I have a ball python that is living in a 40-gal tank enclosure. I just installed a UTH and noticed a warning on the pad that said it should not be used with cypress. I was wanting to move to cypress substrate (currently using Aspen), but that warning has me nervous. If the heating pad is under the tank with glass in between it and the substrate, IOW not in direct contact, is that okay? Or is there some kind of heat transfer or fire hazard problem with UTHs and cypress?
