Just to reiterate, as I'm not sure it landed: the equipment you have may be enough for a first hive, first year. If you get a nuc reasonably early in the spring I think the bees will outgrow your 3 boxes. And as mentioned above it is advisable to have some more equipment on hand (nuc boxes, full size, tops and bottoms) for swarm prevention or retrieval. When you go out and see a swarm hanging on your bush you won't have time to go buy a box or material to make one.... Enjoy!
