[PitOnTheProwl]

Thats cool PitontheProwl. . . what do you use to heat the water to create the humidity? . .. .Heat tape at the bottom laying under the jugs and thermostat? Thanks for the posting the photo.

12 inch heat tape is the only thing that heats the incubator.

How are the water jugs providing humidity w caps on?

Thermal mass nothing to do with humidity.
Helps keep the temperature stable.

Do the containers w eggs have holes in them to let moisture in?

No holes in any of the tubs. Wet vermiculite keep the humidity on point.
