Hi,
I just got a couple of corns. For heat, I am using an undercage heater, the first I have ever used. In the instructions, it says to have enough substrate so the heat will defuse and not burn the animal. However, once I turned on the heater, the corns burrowed down to the bottom. The substrate is a good temperature, but right on the glass in quite hot. I am afraid of leaving the heater on for very long. Do they stay a constant temperature, or continue to rise?
Thanks
Stephanie
