No tape ever. I pretty much use hot glue for everything that one of my snakes could come in contact with. I read horror stories on cornsnakes.com when I got our first snake and was looking for advice on setting up his viv. I doubt I'll have problems with humidity, Houston is known for being, well, humid. I will a hygrometer, I have it already it's just part of the probed thermometer and I'm waiting to get the UTH before disturbing Steve in his new home.
