During the day the warm side is at about 90-93F, with the cool side about 80-83F. At night, these drop to about 75-77F on the warm side and about 70-73F on the cool side. Does this sound ok or is it too cool at night? I have a 60W incandescent bulb on the warm side, which is on for 12 hours in the day. There is also a 13.5W heating mat under the wooden base of the viv at the warm side which is on 24 hours.

My humidity also rises dramatically at night: from around 50% during the day to nearly 80% at night. Is this just because of the cooler temps? Is this ok?
