I am looking into getting whites tree frogs and went to petsmart just looking at some things and they told me that I shouldnt need to get any type of heating lamp and i wanted to check here and see what ya'll think. Currently I have the exo terra hood with a 2.0 bulb in it, it keeps the temp between 71-73 during the day and at night the temp drops to 65-68. Is this an alright temp range or do I need to get something else. I am kinda worried about leaving a heat lamp on when nobody is home or we are asleep so any suggestions?
