Hello,
My reading of material on this topic suggests it is best to blow up from
under the bottoms of the
> frames, not the other way around. Comments

As far as blowing from the bottom, I did, and then walked around a blew from
the other side.
I believe as far as blowing out bees, there is less brace comb and loose
honey on the top. So it is easier to blow from the bottom.
Works great
