screen bottom or super vent holes?
What are your experiences with these two methods? My hive without super holes is starting to beard more then the one with upper vent holes. I have used a screened bottom board as well and it helped. However, I'm thinking the bees may have more control over a vent hole in each super over a wide open bottom board. I drill them in an upward direction to help ensure water doesn't get in, but that is a possible advantage to screen bottoms. My hives are in partial shade, but temps will be to 100 sooner than I like.
