Ambient temps

Hi guys , wanted some opinions on ambient temps , I have my bp in a exo terra glass vivarium , two uth's on seperate stats , hot side 90 ish cool side 80 ish , measured at belly levels , I've been using a ceramic heater to bring up the ambient but it's killing my humidity , so the question is , will ambient in the low 70's measured 2/3 of the way up the tank be ok ??

The lowest any part of the cage should ever get is 75 degrees.

Right now it's 75 ambient , I will turn the ceramic heater back on and be more attentive with the humidity , thanks for the answer

What I would try doing is unplugging the second UTH (cool side UTH) and plugging the CHE into its thermostat. put the probe in the cage, and set the thermostat at 80 degrees. see what your humidity is then go from there.
