That is awesome! I think I will be able to keep the room around 70 all year maybe falling to 68. Belly heat it is. I think the front door will be framed with a large acrylic window. That way light gets in and also if I need vents that is easy to work with. I also want to keep them out reach of kids as some family that visit have little ones so I want them locked just in case. I not building this one to go as affordable as possible because I want it to be a price of furniture in the living room and hold a good handful of snakes. It will be on casters because will be using 3/4" plywood and of course it will be sealed appropriately.
I am a little worried about the ambient holding at 80 but that is why I draw on the experience of all of you. Thanks so much!
Side note:
I thought I would only have one snake and of course that has quickly changed. I think I will incorporate a couple different sized tubs so I can dabble in breeding. I don't want to make that. A business, more of a project for my daughter and I to do in the next year or two. I will probably just buy incubator when the time comes. I guess the breaded was right I did end up getting addicted.
