For hot side for 2 of my bps that have uth I keep it at 90 on top of substrate and under under is 93. I did have to thin out the substrate over the uth a little to have the correct on top of substrate. The lowest my cool side gets in the cages are 79 and the highest is 83 but I like to keep it around 80-82 but sometimes I have no control over it do to the ac in my house, I could turn the ac down but I don't bc I'm still in the safe zone. Generally hot side you want 88-90 and cool 78-82, minimum cool sidr would be 75, max hot 94 under substrate, and max on top of substrate 92 but try for between 88-90. I'm guessing your getting a younger snake so I would aim for 88 for your hot side on top of substrate.
What do you plan on using as substrate?
