I'm interested in your square/cube hive bodies.
(It's been a while since I've looked at your blog.)
1. Have you made half width boxes, so that they could also be used as 6 frame Nucs?
2. Have you run it as a two queen hive?
3. Have you tried the boxes at right angles and does it act as a queen excluder?
4. Are there disadvantages to this size box, other than the weight of a single box?
