I thought of instead of getting more hives I would just add a super to each of the three hives I have. All my current equipment is from Better Bee but I was thinking of getting the assembled 10 frame mediums with wood frames/rite cell foundation. Will the mediums fit the same on top of the other mediums from Better Bee? I guess I should ask the same about the frames interchanging?
Frames will fit fine. I believe Betterbee makes their supers out of 7/8" think boards instead of the 3/4" norm. They won't fit perfectly flush, but will work just fine.
Robo is correct. The Betterbee boxes are made from thicker wood but work just fine. I currently use both on the same hives with no problems at all.
