Welcome to best ball python forum. I am not real good with all the detatils on balls but we have resident expert on the subject. When me and my husband soked bob (his ball python) it is just lukewarm, like gen said if it feels warm to you most likely too warm for your snake.
I also have a leopard gecko, who I actually love to death. Your ball python's humidy should be 50-60%. We got a indoor outdoor themometer that has a probe on it, the probe is on the hot side and the readout is on the cool side and it measures both temps as well as the humidity. It only costs about $15 we have one in each of our tanks.
My husband also uses some kind of green lizard liner he has 2 of them so when one is dirty can put a clean one down.
Again welcome to the forum and look forward to hearing more about your snake and seeing pics. Do you have a name yet for your new baby?
