New BP owner of 3 weeks and counting......

Housed in a PVC enclosure w/ two UTHs controlled by a Herpstat2. One UTH has a warm surface temp in the low 90s and the other UTH in the low 80s. Humidity has always been on the hide side. One unit will read in the 90s and the other will read in the 80s even though they are sitting in the same spot. I've tried to reduce this by changing the substrate from Reptichip to unprinted paper and reduced the amount of water in the exterra water bowl.

The ambients seem to be dropping in the last 3 weeks probably due to the drop in weather temps. Gone from the high 70s to mid 70s. It's sitting at 75 now whereas the room temp is 70 and the weather is damp and 60 outside.

Since it's a PVC enclosure, I don't think I have many options to boost the ambients other then the following:

1. Turn on the LED light in the enclosure which has shown to boost the ambients into the low 80s.

2. The pvc enclosure is in a small finished basement (600 sq ft) heated/cooled by a mini split type air conditioner (which we never use because there was never a need). I'm wondering if it's more efficient to finally start using this unit and if so, what room temp should I set it to to achieve the ambients I need inside the cage?

Any suggestions?? Appreciate the advice.

P.S. I'm also thinking when it's time to upgrade the enclosure, I'll look into another PVC w/ a UTH and a RHP.
