This is the traditional solid reversable bottom board and is made with solid pine, no plywood. Traditionally one would use the larger opening during the summer and the smaller 3/8" opening during the winter. Personally, we prefer to use only the 3/8" opening as we find it provides a large enough opening for the bees, but not so large to increase robbing and other pests like mice.
