Hello everyone. I have finished assembling my hive bodies/supers and I stacked them all up in my house to see how they look. I'm noticing some gaps between a couple of them, and I'm wondering what's an acceptable gap size? I believe it's due to the fact that the boxes are not completely flat on the bottoms and tops. I know that the bees will fill small gaps with propolis but the largest gap on one side is 1/8" and it seems like it would be big enough for ants or cold air in. Will this be a problem?
