So this is what I've faced most every year. I went from double deep brood boxes to single deeps, for a number of reasons. I use mediums for honey supers. This time of year the nectar flow slows but I still have a lot of honey in my mediums, and I don't pull the frames until they're fully capped. I also use OA for mite treatments and we all know that you can't use it when supers are on. My dilemma is that I don't have enough space to store honey supers (currently running 37 hives) and I normally have 1 to 4 honey supers on a hive. It prevents me from treating if needed during the dearth. So... I was thinking about running a deep and a medium for brood, which will give the queen some more room to lay, as well as more room to store nectar & pollen. I can always get my medium supers down to one on each hive. Does it make sense to run a deep and a medium for brood? I don't want to go back to running double deeps.
