I installed my Full set of 6 frames on top of a mature extremely active hive in March 2016. At every inspection I see many bees on the visible frames, crawling into cells, etc. but to date have not seen a drop of honey. Possible explanations I have thought of include: they are preparing the cells by sealing up cracks and building out the walls to get ready to deposit nectar, they are adding honey to the inner reaches of the frames out of sight on the harvesting end or the side window, they are filling every nook and cranny in the frames below to avoid the Flow Hive, they swarmed and fled without detection, they don’t like me.
Our early spring seemed a bit wet and not very conducive to foraging but things improved. Yesterday I harvested about 25 lbs of honey from one hive that has never seemed as active as the hive under the Flow Hive. I didn’t even go below the top super and guess that I could easily have harvested 50 lbs from that one hive if I had wanted to be more aggressive. It is clear that foraging is good and all other hives have honey.
I have been avoiding inspection of the lower supers, one deep and two mediums, since I planned to let them have all that honey for winter. My next step is to go in and see if there is some honey forming in the interior and to check for status of lower supers.
Does my experience ring true for anyone else out there?
