All brood boxes no supers to keep the same size frames, I add boxes very similarly to the Rose method,based in Devon and Bibba member, I’ve thoroughly enjoyed all the webinars! Excellent
I run the cold way as it is quicker to inspect hives, but with a twist. I run twin national boxes, 8 frames in each. Corex block fills the gap. This way the bees can go up and down as they do in the wild.
