Since we are now in winter the drop in temperature and humidity levels has made it necessary for this frankenstine of a setup lol. I purchased an oil radiator space heater and placed it on the warmer side of his cage (his basking spot is in the left back corner of his cage.) Then next to the heater I have placed an ultrasonic humidifier so it just barely wafts the humid air on to the top of heater. Before I added the heater and humidifier the cool part of his cage would never break 65 during the day, and the humidity levels would stay at 30% and below. Now his cage has a perfect temperature gradient from 84 in his basking spot to 72 in the lower parts of his cage. The humidity levels also stay at a pretty constant 50% between misting. Does anyone see any potential problems/safety issues with this set up?
