I keep getting people talk about Flow Hives to me. I have little interest in such, they're way too expensive to be of any practical benefit. My neighbour saw me doing some beekeeping, and asked that I supply her with some bees when she gets her Flow Hive: they've been waiting 9 months for their order, cost them $1700 for I believe two supers/frames and everything. Their knowledge of beekeeping is everything they learned when doing a course, that taught them how to open a hive, and other super basic stuff.
