My 2 cents, I gave it a go this year on 15 hives. Every one of them swarmed even with weekly checks. It requires a lot of attention, which means time and effort, which is what I was trying to save in the first place. I’m not giving up on it, but approaching it differently next year. 2 boxes in the spring build up, then moving all brood into the 2nd box, shaking all bees into the bottom box onto 5-6 empty combs and QE between them. She just needs a ton of space in the spring.
