ok, to be honest, the question was more theoretical as I will be setting up his enclosure next week (52Lx21Wx24.5H) built by custom cages. I have him now temporarily in a 29gal glass tank. He is (i was told by breeder) about 2months old and just under 7".
i'm currently using a 60W Basking Bulb with his branch of wood coming within about 6" of the bulb.
The opposite side of the tank doesnt seem to really be much warmer than room temperature as the top is just a screen cover. A Zilla Digital Thermometer/Hygrometer read 120 at the tip of his basking branch (doesnt seem that hot to me there, but i'm not a thermometer). He does get a
bath every day so i think that should help with his
hydration (just got him sunday so he is not yet eating due to relocation stress).
I am not yet sure how everything will work out in the new enclosure till i have it all set-up, but using the current temporary setup as an example, getting a stronger bulb will just raise the temp of his basking spot and getting a weaker one will give off less heat to the rest of his enclosure. Is there a need to lower his basking spot further away from the bulb? or would he know on his on how close/warm he needs to be and only climb to that height to bask? and as far as the cooler side, if he gets too cold, would he know to just hang a little closer to his basking site where he'd be warmer?
