It's at about 45% now and I can't figure out how to get it to raise up. I have back heat (cause the tubs would tear up the heat tape if it was belly heat cause its such a tight fit) and the warm side of the tub is sitting at about 90-92 degrees. Now I have a snake trying to shed, but its way to dry for her to shed, how do I bump up the humidity in a rack system?
