Yep...my humidity is too high! lol It's running about 80% during the day, but when the heat and lights shut off it sky rockets to 99%! I'm leaving my water filter and heater running at night, which is the driving force. I considered having them shut off too, but my dragon likes to swim first thing in the morning and I don't want the water cold. I've got two grommets that can be removed where the cords go in up top. They really don't seem to make much of a difference though. Any suggestions?
