I run 3 long hives in wood which are designed to take 22 off 14x12 frames with 1 entrances on either long side. ( it takes a standard entrance reducer ). It has a fully removable and sealed centre divider, plus it has a gabled roof that I slid off towards either side which then rests on the ground and side of the hive and that gives me the benefit that I don’t have to lift the roof or carry its weight - old age and a bad back!
I can put 2 full-size supers on it as high as they need be, as the roof is telescopic, but I also have a lot 5 frame supers which allow me to put 4 of them on there and are easy to lift ( or less than 4 supers using 5 frame sized crown boards to close off the none supered parts. The 5 frame supers are what I use on my 5 frame nucs, so I have plenty. I’ve even put 5 frame brood boxes on in the past when the Heather honey flow was good.
I use the long hives for honey production but I got them for thier preliminary rolls to make very big colonies to bolster up weaker hives without having to lift box after box, and they are really easy to split to stop swarming if need be - all pretty much without lifting a box.
The disadvantage to them though is if used as a single hive or with different size colonies is the fact that if you have to put a super on the big colony, you also have to put a super box on the other side to hold the roof straight ( in this case I put the super on top of the crown board on the small or empty side to keep the heat down below whilst putting the crown board on top of the super on the good side).
I enjoy the change having a few different hives bring to the mix when working my long hives and I think that all hive designs have a place in today’s apiary. As long as the bees are being looked after, I stand by my comments elsewhere that there is no right or wrong way to this beekeeping malarkey, it’s all about what the individual beekeeper want to do themselves and not secome to pressure from other so called experts forcing thier way - or no way attitude.
