This is my enclosure. During the summer the temps have been perfect. We usually have pretty cool winters and the building I will be keeping him in is not insulated. Daytime temps will not be a concern. At night however, I'm still trying to decide. I'm thinking CHE with an adjustable stand and either a timer after my MVB turns off or use with a thermostat. Definitely getting the 100 watt bulb just in case. Then do I put the secondary heat source over the hide area or near the middle. Feel like I'm way over thinking this.
