I am lucky enough to live in FL, where humidity even in the air conditioned house is not an issue. I keep Veileds and Panthers EXACTLY the same (inside and outside), with the exception of a slightly hotter basking bulb for the male Veileds. The outside guys are outside with no additional heat until the temps hit 50 at night with sufficient day time warm up. This year they have been in all winter due to the freezing temps.
