Thank you so much! I suppose I should have thought of this but honestly I am totally frazzled.
So, going on from this information, if this is the case then my ambient temps on the warm side are too low when they're sitting at 80*. My issue with this IS I *could* move my heat lamp closer to the enclosure (I have it on a stand hovering quite a bit above the enclosure) and I have tried this, which does raise the ambients, but then my surface temps will get too high (I have a thermometer probe measuring this as well). It is a little bit nerve wracking trying to get a perfect balance with the UTH and heat lamp, but I am determined to do just that until I am able to set her up in a PVC enclosure.
So, my temps on the cold side are normally 77-78, ambient (middle) is 77-79, hot side ambient is 80ish, but her surface temps (hot spot) are constantly 88-91.
Would you happen to have any advice on what I could do here? I'm starting to run out of options in my head.
