I would recommend the cool mist ultrasonic humidifiers for humans. You might want to get your water for it from those refill stations that most supermarkets have. This is supposed to be RO water with no minerals which will clog your humidifier.

With a little ingenuity you can also modify these with some PVC plumbing parts and clear vinyl tubing and keep the unit outside of the enclosure. Then run the tubing to the top of the enclosure so the mist falls from top to bottom.
