Re: Langstroth long hive question
I thought of this exact design, so to attach horizontally 2-3 nuc boxes.
For now I decided against this way and just build proper horizontal hives instead.
Still - this is a valid way, I think, and may still do it.
Do be aware that the final product will be heavy and bulky and prone to fail at the point of the attachment of the two boxes (not a good thing).
However, when doing the same with small nuc bodies, should be manageable and have merits.
Main reason people are not doing this - the entire idea of horizontal hives is still a novelty in the modern N. America (a really well forgotten old way, but now coming back).
Otherwise, I don't see any reason of NOT doing this.
