Going Insane! Please Help me Perfect my Tank!

[Hugsplox]

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.

A lot of the issues you're describing can be fixed by experimenting, and that's best done without your animal in the enclosure. This is typically why it's recommended to set everything up and let it run for a week or so before you bring your new snake home. Obviously your animal is already in there, so my recommendation would be to make very small adjustments and check those temps religiously to make sure nothing gets too out of whack, or that your snake is in any danger of overheating or being burnt.

I don't want to recommend you make any major changes, I think you may be able to solve some of your issues just moving some things around, I would just again, recommend that you do all of that a little at time.
