My redfoot tortoise laid 3 eggs yesterday. I immediately put them in the Hovabator incubator, in dampened vermiculite at 30 degrees C, with water in the troughs in the bottom of the incubator. The humidity is only 72%, and I need to get it up to 80%-100%. Does anyone have experience with automatic misters or foggers in a Hovabator? I want an automatic device on a timer, so I don't have to open the lid often to mist manually.

I live in New England in a drafty, 105 year old house with radiators (dry house), so I need to keep that incubator closed as much as possible.
