What temps and humidity levels? For basking I use a dome fixture with a 60 watt incandescent bulb during the day (88 to 92 degrees at the basking site) and no lighting at night. The temperature drop at night is absolutely natural and lighting can prevent solid sleep patterns. For UVB I use a 22" Arcadia 12% (heavily planted enclosure) along with 22" 6500k plant bulbs. If you are struggling with humidity levels you could use a plastic shower curtain wrapped around three sides and see if that helps. What are you using for lighting?
As for misting I use a MistKing with two double nozzles a few times a day (Veiled chameleon).
