So, I had gotten the thermostat issue figured out with this enclosure I bought, but I've come across another problem. Tried running it overnight two different days with two different thermostats set to almost 100 degrees, and both times the floor of the enclosure directly below the panel didn't get above 78-80. It's a 120 watt Reptile Basics RHP that has to be a decade old minimum if not more (guy I bought it from said nothing's lived in it for 8 years) so I'm not sure if it's just not working as well due to age or if it's simply not strong enough for the enclosure it was installed inside of in the first place. The enclosure itself is 72"x30"36".
As a side note this will be the adult home for my VBB and I'm aware they prefer cooler temps anyway (she's in a QT tub setup atm), but I think barely hovering at 80 is stretching it, plus idk if such temps will remain that way once the months get cooler...
