I am planning on experimenting a bit with the flow frames and polystyrene hives and comparing to our traditional langstroth hives. I am thinking about using 6 flow frames in a 10 frame langstroth with one follower board or feeder on each outside position. This will allow me to use full size frames, the flow frames and cut down on the weight of the supers without going down to mediums. I am also thinking about doing the same thing with a polystyrene hive.
