The Ivory I bought recently has only been using his cool hide. I have taken him out a couple times and put him back with head at entrance of hot hide and he crawls and he will stay in for one night and then goes into cool hide and stays there until I take him out and put him back in hot hide again and repeats this each time. He is in a T10 with a 88w pro products rhp regulated with Herpstat 6 set to 91 on ground with 87-88 in hide and 82 cool side with 80 inside cool hide. He has 2 reptile basics large hides and the only difference is the hides are turned different ways. My 2 other bps use both but tend to spend more time in hot hide and if it were up to him he would not move from cool hide I don't think.
