"We evaluated the hives for every metric: honey production, brood area, survival. We could never see any difference between solid bottoms vs screened bottoms. I came to the conclusion they don't make any difference."
Our winter is 6 months. I think most beekeepers consider screened bottoms as safety measures. During winter hives are usually not visited, and screened bottom, or wood sticks between bottom and lower box, ensures that no matter what kind of events might happen, heavy snow storms, two months of -20 C, heaps of dead bees on the hive bottom or ice blocking the entrance(with 6 mm mouse guard), the air is coming through. Ventilation is considered more as a vital survival factor than something which would increase honey crop. And ventilation through the bottom, not through the hive cavity, has become the norm here. I remember top entrances, back in the 80s beekeepers drilled holes in their boxes etc, but today nobody uses them.
