So, I still haven't gotten a beardie yet, but am getting all the necessary supplies. Already got his viv, an exo-terra 36x18x18, am probably going to use non-adhesive shelf liner as a 'substrate', a reptisun 10.0 for uvb and a 75w Repti Basking Spot Lamp for the hot side. My question is, can I just get a CHE for the 'cool' side and just be sure that it stays around 85F all the time? Or do beardies need it cooler at night? I know they CAN go down to 65F at night, but that doesn't mean that they SHOULD, does it? Any and all info would be greatly appreciated
