Ok- an update!

I got home and remeasured today. My hottest spot was about 92 under the substrate up against the uth, and my cool side is reading between 75-80. The AC wasn't on all day so it's warm in here in general so that might change when it cools down, but it seems like everything is good now! I'm still going to get something for the heat lamp, a thermostat or something. The tank sat overnight so I'll keep an eye on it to see my temp changes once the AC cools down the house but I think we're gonna be ok! I moved my two thermometer probes, one is under the substrate on the hot side right by the uth and the cool side ont is clipped to the top lip of the tank on the cool side, slightly hanging down. I might try a bigger bulb if my temps drop too low again after the ac cools it down, because it seems like maybe that's what it needs.
