I live in VA near the coast. My climate is usda zone 7. Winter can have a week or so at 15F. Our first frost can occur sometime in November with spring getting started in Late March. This would be similar to the middle part of NC and the upper parts of GA and AL. How much space do you give your bees for the brood box in these areas? I have 2 hives in 10 frame deeps that were started from nucs and I have 2 very small nucs in 5 frame equipment which I may have to combine.
