Oliver, to simplify things in summer I have a hotspot of 88-90 and the cool side is naturally in the lower 80's. This climate is then kept as such until winter/cooling time(for animals of breeding size only) where one slowly lowers the temperature to the 60's. There are different opinions on how long the animal should brumate for, but the recommended time is generally between 1-3 months, thereafter one slowly warms the enclosure back to it's 'summer' temps. Search for n. wheeleri and you will get opinions/rearing techniques/enclosures from different forum members' previous post too which always helps. Oh, and I spray one wall of my enclosure, and/or a plastic leafed plant 2-3 times a week and they lick the drops off. They like it dry, but occasionally(once a week, or once every 2 weeks) I will slightly moisten the hide that I keep on the cool side of the enclosure(I keep 1 hide on the cool side, 1 on the hot side). They are easy geckos. The males are more feisty than the females, but they too can bark and get worked up. The females are very horny geckos, I was cleaning out some bombs from my female a while ago and I accidentally grazed her tail with my finger and she started to get all worked up(thinking I was a male!) She lifted her tail, started spazzing out, and was backing up toward my hand, lol. Needless to say they are very fertile geckos. Hope this helps a little.
