Give me a couple of days, I'll draw something up.
Here is a pic of a thermometer. Its stuck thru one of the holes that the hot air travels through to get to the box. It is showing 200 degrees F. It is sunny and 70 degrees today. I'll add another one at top of box, which
should be less since air has to leave to get the moisture out.
The lid of the box is currently a piece of glass. Probably not permanent. My thought is the glass will tell me if
water is condensating which would neccesitate more venting out.
