Hi everyone i just got my ball python a week ago and everything seems fine and she seems happy, eaten twice, shed (even though it was patchy, but i think low humidity was to blame) but my question is about night time heating. during the day i use a ceramic lamp with a heat bulb, and my warm end is 90deg and my cool end is78-82 depending on how hot the house is during the day. but at night time i've been turning the lamp off to give her a dark/night cycle and the temp usually drops to 70-75deg. now i've had some people say you should let it drop in temp at night, its some sort of nautral day/night cycle thing and others say you shouldn't let it drop at all. so im just a little confused. should i get a under tank heating pad to turn on at night to keep the temp up or is letting the temp drop fine? any help and advice is greatly appreciated. thanks guys.
