Typically, Nuc (or Nucleus) Boxes are used to hive a small colony of bees-- usually a package, swarm or split. At Betterbee, we use Nuc Boxes in some additional ways as well:
Double Nucs are an excellent method for Northern beekeepers to minimize their dependence on package bees. These allow the beekeeper to prepare nucs during the summer to overwinter and provide nucs for sale or use the following spring. Bees overwinter in 8 frames in a four frame over 4 frame configuration. The overwintered nucs that we sell are raised in these nuc boxes.
