I recently built a new bottom board from the 10 frame Langstroth hive plans on Beesource. The drawing shows that the 3/8" opening is on top. Is this the entrance side or do they just have the bottom board upsidedown in the plans?My old bottom board used a 3/4" entrance reducer. There isn't much room for an entrance reducer with just a 3/8" opening.
I went ahead and installed it as shown in the plans and the bees don't seem to have a problem with it. Should I flip the bottom board over?
