welll i have a heat gradient thats for sure cuz i monitor all that stuff the humidity lvl is usealy around 60-65 when it drops below that i mist it. the hot side is 85-90 the cool side is 77-80 i have a water bowl. 2 hide spots one on cold one on hot and even 1 humid box in case of humidity. i want to add that this is the 3rd night thats he has benn with me and everytime i look at him hes trying to get out. i have a screen top. with a towle on it and around the heat lamp i made a cover with a hole in it for the lamp out of tine foil there is a 5 inch gap for fresh air. i was wondering if all the falling could hurt him badly. i would post a pic but i dont realy kno how i just took some.
