In the past, I've lived many years in the desert. Humidity is going to be a challenge for you with this snake, especially if you're trying to keep the whole enclosure humid. Best bet is to make a "humid hide"- with a (new!) large plastic food container big enough for your snake with a snap on lid. Cut a doorway hole in it, & keep it half-filled with moist sphagnum moss. You'll have to re-moisten it every few days to once a week when it dries out, but it will stay humid much better than the whole enclosure will.![]()
Note- the "humid hide" should be midway or on the cool side- not on the warm end, & it does NOT replace the cozy cool & warm hides (-those are dry). BPs aren't the easiest snakes to keep- despite all the sources saying they're "great beginner snakes"- because they need higher warmth & higher humidity (that the warmth chases away)- it's hard to get their conditions just right. Plus they're shy snakes that aren't always easy to feed- they rely more on warmth of their prey (because they use their heat sensing pits to decide what's edible) so you end up warming f/t prey for them. But you'll get there... & the trade off is that they're docile & pretty snakes that stay a comfortable size to handle easily.
