Thank you!!
Temps are a bit lower than I'd like, but hopefully nothing dangerous - it's a gradient of 76 - 83 (2 f or so higher on sunny afternoons), with an 88 hot spot. I see him in both the warm and cool hides so I've tentatively assumed he's not uncomfortable.
As for humidity, I've been trying to manage it (baked substrate, additional air holes, water on cool side), but it's still high - usually in the 70s, so I air out the tub at least once a day. I've held off on a humidity bump for the shed since it's high already, I hope all goes okay.
I'm really eager to get a PVC cage where I can dial everything in more perfectly. I'm waiting to see how the heating in my home is in the fall and winter, and if there's any issues I'll spring for the PVC. (still trying to decide on heat tape or RHP....)
Also, I just peeked in his hide and his eyes have cleared up! I'm glad I snapped a pic last night or I might've thought I imagined it haha.
