Re: Control Winter Moisture
Another vote for the Honey Run Apiaries' All-Season inner cover, but with the foam insulation as supplied from Honey Run. Our Denver winters are cold and dry. For the winter, I simply insert the foam insulation into the All-Season IC. I don't do anything else to the hive, i.e. no wrapping, no moisture absorbing, etc. In other words, my hives spend the winter with insulation on only the top, and with a top and a bottom entrance.

I think some people may over react to the cold, and end up cutting off a hive's ventilation by adding unneeded insulation, which then kills the hive by causing moisture buildup. Unless a hive is already impaired for other reasons, I would suggest insulation is only needed when very far north, so beeks not in the extreme north should first focus on providing effective winter-time ventilation. Again, this is for a healthy hive, meaning a good size cluster and good honey stores.
