I updated my Sulcata enclosure to a Closed Chamber a few months ago thanks to this forum. Now I can really see how big of a difference it makes. My sulcata was starting to pyramid because I kept her at room humidity 47% now that I keep her at 80%+ she's growing smooth! Oh and since it's a closed setup now it is easy to keep the whole enclosure 80 degrees + and she's way more active than a few months ago.
