Also,IMO,I'd get a separate humidity gauge and temp gauge... I'd leave the humidity gauge center of tank about 4" from bottom of the tank..and I'd put the heat temp strip n the hot side about 4" up from the bottom as well and about 6" inches from the hot end of the tank over..get a probe,place it under the bedding inside the tank right above the heat mat,hold it down with a piece of aluminum tape..and regulate your heat mat..
I believe where u have your gauges set you will be getting false readings.
