I just got a beardie a few days ago and was curious as to how long everyone leaves their lights on. My viv is in the basement so she gets almost no natural light. I usually give her her breakfast 20 minutes after the lights come on. I leave the house by 730 or 8 am, and usually don't get home till 5 or so. If I leave the lights on for 12 hours, it usually just makes the cut to give her 2 hours to digest after dinner. My main question is if I turn her lights on at 7 and off at 9 or so, will that do harm/screw with her sleeping schedule? Thanks for any help guys
