I have a plan underway to ‘super’ the Flow onto a Top Bar Hive, well add it to the end so I don’t have to change all my bars (and defeat the purpose of light-weight top bar beekeeping).
Here goes:
A normal Lang box on left, and a small TBH on right:
I cut a large hole in the end of the TBH:
and in the Lang so they line up:
add Flow frames
and a queen excluder if you like (I prefer not to)
view from inside, with a small hive beetle trap showing on the floor
view from the Lang end
view from TBH end
the complete bits
Now to add bees!
