Go to target and get 6qt tubs (a little over $1 each). Set each one up with paper towel on the bottom, some kind of hide (you can use a plastic container, like the ones that people get mealworms in, with a hole cut on top or on the side), something to lean against the hide for it to climb on (you can use a piece of cork bark or a dowel), a small jar lid for a water bowl and a small milk cap or other dish-type thing for CGD. Keep 1 hatchling to a tub. You don't need to punch holes, there's plenty of air exchange. Mist nightly. You can stack them on top of each other. This is how I keep my garg hatchlings.
I used a teeny tiny drill bit on a dremel tool and put a bunch of holes in the lids of mine. Make sure you take the lid off while you drill it and brush away all the plastic shavings. If you're unsure if any are left, swishing it around in a bucket of water should do the trick. If you don't have a dremel tool, I'd carefully consider getting one. I use it fairly often when modifying different things in my reptile enclosures.
Yup. Simple and to the point. I have a dry hide I put in the other end too. You know those papery drink holders they give you at McDonald's and places? I got a bunch of those and just cut them into 4 pieces. Each "cup" is a cheap and disposable dry hide. ;-)
