Temps...

[Craiga 01453]

When you asked what I’m keeping in there, I thought you meant the substrate and stuff. I will be keeping a ball python. I was supposed to be getting her tomorrow, but waiting until I’m certain my temps are right. I really think I’m overthinking it a lot. Making it more difficult than it really is.

And yes, I have a thermostat on my uth.

It sounds to me like you're just one step away. Tweak the light situation and dial it in with your t-stat and you'll be good to go.
Don't over think (I know, I know, easier said than done, hahahaha). Nothing has to be "perfect". You'll learn and you'll grow. You're off to a great start. Huge props for having your set up ready BEFORE bringing your snake home.
