I am converting my sulcatas outdoor hide so that she can be out full time now. We have created a back door for her to get into her enclosure through the back of our garden shed. I am having a hard time keeping it warm AND humid at the same time. We live in Arizona so it is naturally dry most of the time, and can still get pretty chilly on winter nights. Most of the outdoor enclosures that I've seen don't have have anything to hold moisture. Do I need to use plastic somehow?? BTW, she is much more mature now since the avatar pic...4 years old and 3.5 pounds.
