I have a nuc size(5 frame) Langstroth box on one side of my TBH, with a large hole into the TBH.
Just put a Lang split into the nuc box. They will expand into the TBH section eventually, since there is nowhere else to go.
Hoping, by exchanging Lang frames, to push them over into the TBH completely, then over to the other side of the TBH, so I can use the nuc box again for another Lang split.
Well, that?s how I think it could be worked. It?s my first TBH.
