Maybe you herd this before but if u switch to tubs, heating and humidity issues will be eliminated. I struggled with my old setup with a glass tank, temps were up and down several times a day. Switched to tubs, and was the best thing ever! Sure, tubs aren't nice to look at, but I figure if I wana look at my snakes, I'll just take them out. Also once u get the tubs in a rack, makes owning snakes soo much easier, and a cleaner look!!
