Cool mist humidifier?

[naoki]

HygroThem works great (and the price is really good now). I have one for orchid grow tent, controlling a normal humidifier and exhaust vent. Then another one for a music instrument room. One unit is slightly off in terms of RH reading, but it's not a big deal (you just set the set-point a little higher to compensate). I don't know about the reptile humidifier, but it may be better with the normal humidifier. Living in North, I checked out quite a few humidifiers, and I like this one:
Amazon.com: Crane Drop Shape Ultrasonic Cool Mist Humidifier with 2.3 Gallon output per day: Health & Personal Care

With ultra-sonic humidifier, you might want to use RO water if you don't like the white dust.
