During the day I have a hot end which is 35-37 and the coldest corner of the enclosures is about 23/25, they spend all day in the hides at the coldest end, then they both come out at night and bask under the heat lights which at the moment runs 24/7, I will be turning night heat off shortly once it warms up as my snake room can get very cold at night as there is no heating out there!
