The thermostat keeps the mat between 91 and 95. But on top of the bedding it only reaches 85, so I put the extra light on it.. it's not the thermostat, it's the ambient air that keeps changing in here..

So a month in the high 80s is ok?

She's got a Zoomed Hygrotherm. It does humidity as well.

Right now she's at 91.2 and 82.4 but in an hour she could be at 89 and 80....
