This year has been busy thus far. Things were hot and heavy through May and June, but now there aren’t as many pressing issues until extraction time. There are some laggard hives, but for the most part all the production hives were supered and now I’m just waiting on them to finish some capping. Extraction time is being planned for sometime mid-August.
It is during times like these that scheming begins. This year there is going to be an overwintering experiment. I have an issue with the quilt boxes I use for overwintering, too much moisture. Last year when they were removed all of them had mold growing on the burlap. I know it is growing because the moisture is being retained in the burlap, which in one way is good. Better the moisture be there and retained than to be dripping back down on a cluster of bees. I don’t like the idea of mold growing on the inside of the hives so I need to think of something.
There will be three groups in this trial. The 21 hives will be assigned into 3 groups of seven.
Group 1 will get the normal Warre-like quilt box. This configuration provides excellent insulation and it wicks moisture up and away from the bees, unfortunately there is poor ventilation. I have been using these for two years and wintering success has been good. Why do I insist on changing it up? If there is no experimentation I am foolishly assuming that the current way of doing things is the absolute best it can be. There is always room for improvement.
Group 2 will have a top entrance that I have seen pictures and video of. It is used by a gentleman named Tim Ives (liquidgold2009 on YouTube). He uses what looks like a 4-3/4″ comb honey super ON TOP of a modified inner cover. In the winter time he places foam insulation inside the comb honey super. This configuration provides some insulation in the winter and improved ventilation over the Quilt box method. The bees can still come and go through the upper entrance through the winter on good bee days.
Group 3 will have one of the top entrances made this summer. (See Top Entrances) These will provide no insulation value, but will give the most ventilation. I don’t know how they will do in winter, but the bees seem to be loving them this summer. Initially the bees were not using these entrances, but as the summer has progressed they have been using them more and more.
