I am waiting on the arrival of a Zoo Med ReptiTemp 500R Remote Sensor Thermostat. I am not sure where to put the probe. I know enough to put the probe in the area of my UTH pad, but I am not sure if I have to attach it to the glass on top of the pad or does it have to be between the pad and glass. Any suggestions? I am also having a hard time keeping the humidity of the enclosure at the correct range. I currently have plastic wrap over 3/4 of my screen top and misting every 2 days. I have a digital barometer, which shows the level decreasing after 2 days to about 70%. I replace my old bedding with reptibark. Any suggestions besides misting more often?
