I'm keeping my ambient temp on hot side around 83 degrees and cold side around 78-80 day. Night the whole tank levels off to about 76-78 with the hot hide being a constant temp day and night. I think it's just gonna take some tweeking and I'll get it. My humidity is at 50% and bumps to 70 when I spray and slowly lowers through the day. I have the top 80% blocked with foil tape( on the outside of course). I just notice he's not using his hot hide so it makes me wonder even though when I check the ambient temp of his hide its 90 and surface temp with the gun is getting up to my 90 deg mark. I had to bump up the thermostat to 103 and I'm getting anywhere from 88-90.5 with cooler patches throughout
