I have a thermometer that I forgot to put back in there when I put him back.
Ok about the hides... what should I use? The rock den is VERY tight on him, like he doesn't even completely fit in it.
Yes that is what the books are doing. The lid has a fairly large whole in it, so I use a metal weight taped down and those weights on top of it. I really don't think there is anything wrong with that. I use lamps because I have heard UTH's cause burns. It changes because I move where the lamp is and since the box is so tall, it is warmer there.
