The last three days I have put my 4 year old Greek outside for about 30 mins at midday for exercise and UVB. I live at 7200 ft so the sun is powerful here. Air temps have been 45. But ground temps are 65 and his carapace stays araround 72 in full sun for that time. Also, it high desert so it’s dry not damp. I can be outside in a tee without getting cold (although I’m more comfortable in a long sleeve). He seems to enjoy himself and moves around checking things out and is fine when I bring him back in. What do you think?
