The post is about belly heat. My original point was that I only use a RHP in my cage without a heat tape. and my ambient air temps and floor temps etc....seem well within a good range. I wanted to see what others though on going this route. Now I'm kicking thought back and forth with kitedemon about ambient air temps. He has been very helpful in bouncing what ifs and his experiences with me. Now I think I answered all my questions for now. There are too many variables and cage styles to have one correct way. Thanks all
