i have a uth under that pretty much stays off for the most part. what you see on top is a ceramic heater. thats pretty much what heats the tank. the light is a floresant 18" on the inside going across the back. i wouldnt say any humidity probs. look how big the water bowl is ... stays about 50% and its still been chilly around the area. when it warms up humidity is higher around here . yes herpstat 2. i go out of town alot, and i really like my snake sometimes ill be gone 2-3 days.. last week i was out mon-fri.. i feel ok knowing the temp will be fine. it works awsome....

i think my tank set up was um.. just under 600
