DO Not put them in vermiculite and water!!
You want to put then on sand or some other dry medium. Too much humidity will kill them. I incubate them at about 82F and they hatch in about two months. You want the humidity to be about 30% to 40% max. I usually put a separate cup about half full of water in the incubator to make sure it does not get too dry. It just sort of depends on the conditions in your area. You can use a cup with holes or without, whatever you want. Just make sure that either way it has a lid, and that if you do use holes they are very small so the hatching can not escape. Honestly, the hardest part with them is not hatching them out, but keeping the hatchings alive. Their small size means that they dehydrate very quickly and they need either pinhead crickets or fruit flies. They seem to do better on the crickets. Do not over feed them as they tend to be afraid of their food at first and if they are swarmed by too much food they may never eat. Otherwise you can keep them just like the adults, although I recommend keeping them on paper towels until they are big enough to safely digest sand or whatever you keep them on.
Also, if they are laying eggs be prepared for many more. These are extremely prolific little geckos. The only way I could get mine to stop breeding was to separate them and take all heat away from the female and greatly reduce her food. Just separating them does not work as the female can store sperm for quite a while.
Hope that helps.
