Ventilation

[Anduril]

So, did you ever use a little smoke on a strong colony that is fanning well? Just a little whiff on the side of the solid bottom, where the bees are fanning in a group....facing out. Of course, the smoke wafts away from the entrance. But give a little whiff to the other side of the solid bottom. In it goes....until the bees realize what's happening, and then out comes the smoke.

So, the bees draw air into one side of the solid bottom, up and through the hive, and down and out the other side of the solid bottom. Good enough for the bees, good enough for me.

That's what I was taught and observed 35 years ago when I used solid floors.

Just pointing out that the same seems to happen with mesh floors as well
