Starting at the end of April I cut off all my hot spots and only have my snake at room temp which is a nice and toasty 86/88 which translaste into 84/86 in the racks during the day with a night drop of 4 to 6 degrees as night.
I have been doing this for the past 2 years since moving to a new house and my animals adjusted perfectly.
Animals can be kept various ways it's mainly about being experienced enough to recognized signs of stress and finding the setup that work for your animals and yourself.
What I do is very different from what I recommend to new owners getting started however once someone feel comfortable enough they should definitely experienced around.
Among big breeders VPI is one that does not offer a hot spot and keep their animals at room temps.
