I just switched from Aspen to Repti-Bark, and found that the repti-bark was a better (worse?) insulator against my UTH. I had to adjust things around to re-gain the belly heat and bring up my ambient temp.


I also had read that Repti-Bark would hold humidity better, but I'm also struggling with it in that regard as well. Just part of the fun of changing things is adapting your practices to get what works
