I have had my beardie since March and I feel pretty comfortable with many things regarding her at this point though this will be our first "winter" together. I put that in quotes because I'm in AZ and of course she lives in a controlled environment.
Do I need to make any changes to her lighting or environment at all for the winter, really? Our house doesn't get especially cold and on the few nights of the year that it does get cold we turn the heat on to keep it comfortable for us, of course. Do I need to change the time the lights come on or go off at all?
I just want to make sure she is comfortable. She already did a long brumation in August/September. Should I expect another one?
I leave my lighting on the same schedule year round. I used to adjust it but didn't find it to make a difference. If the temps in the tank stay above about 65 overnight you don't need an additional heat source. I'd imagine in most of AZ (unless you're in the mountains perhaps) it shouldn't be an issue.
