If I may... (or not )... What you'd be looking for is a cool-mist humidifier.do you have a place to get them from, or a certain brand? do you think i could find one off of amazon, or just in general a pet store?
Humidifier vs. Vaporizer
Some are sold as that, and some are sold specifically as reptile foggers. The only difference AFAIK is that the reptile foggers tend to cost more for what you get.
Many of both kinds are sold on Amazon. If you look at these two links, you'll see that they look almost identical. You can also see the differences in price.
There are many threads in the archives on setting one up for an enclosure.
