I actually have 2 uths on dimmrs set at 92. I also have a 75 watt infared and a 50 watt sunglo on dimmers to with the sun glo set on 12 hrs day 12 hrs night with the infared running 24/7. I currently use jungle mix but bought repti bark and will be changing him very soon like today. I went away from aspen. Also identical hides aren't really required well from my experience there not. I juss cover the hides with fake plants vines and leaves. Spray the leaves 1nce a day and he's great. I have friends with snakes and their jealous of my husbandry and care. Its all really trial and error as long as humidity and temps are good.
