Cave, Chest Freezer - Humidity Control

[sominus]

Its been a while since I posted here, but lo and behold, this is exactly the question I need to discuss..

I was using a large dorm-size fridge which worked OK, but the problem was that the cooling element is inside the box, and if I needed to raise the humidity it would always just freeze to the elements, which really messed things up and didn't achieve the end result...

I was thinking about a small chest freezer with a temperature controller in which I would place a humidifier...

Thoughts?
