Seppo,
It is great to see you are still monitoring the list.

The article is informative and answers more questions than just temp
control. One thing I have taken away from it is an appreciation of the
role of moisture in the hive and mite health. Less is better, so good
winter ventilation is a must.

There are a lot of excellent articles at this site.

Thanks, Seppo.
