As far as the holes, I always put them right above the level of the substrate, a bunch of them, that way you get maximum ventilation when your substrate gets damp. I've tried just using holes in the sides, all sides, and not putting any in the top so the humidity is trapped inside, making a humid micro climate, but that causes too much humidity and I get mold, and even mites once. They were fine in the winter, with the heater drying the air in my room, but when springtime heat and humidity came upon us, the heater kicked off, the mold and the mites appeared. I would just go easy on the topside holes, that way SOME of the humidity escapes, but not all or quickly. When you do it like that you have to kind of experiment, and this whole matter depends on the ambient temperature and humidity in the room you keep your tarantulas in, so it will be different for different people. You just have to experiment a little. Lately I've been putting holes in in the top at the far side from the water dish, so theoretically the humidity had to "travel" through the enclosure to escape. This has been working for me..but winter is approaching...so I kind of keep it in my mind to monitor the ones that need the humidity, and I stick a finger in different parts of the substrate to actually feel how damp or dry it is. Hope this helps, let me know how it goes for you.
