We do use eight frames as nucs. When creating the nuc, we rarely fill all eight frames. Usually six or seven, sometimes as low as four. Depending on available resources and the goal.Does anyone use 8 frame medium boxes as nucs? If so, do you actually use all 8 frames? I've heard they're the same volume as 5 frame deeps, and I run all mediums so it seemed like a good way to go.
