I really like the ONE PIECE BOTTOM BOARD in a PALLET is a real nifty idea for bees and supers CONSTANTLY being rearranged, moved, split, etc..
I saw these in person, I saw them inspected, frame rearrages, super adding, medication and finally loading onto a truck, tied off and properly rigged for any trip so that everything is secure.
I'm old school on this, these pallet-bottomboards are wax free, clean easily and have little issues with burr comb. I think the EIGHT FRAME DESIGN which is 2 less frames and about 3 inches shorter than what I'm use to using. I like 8 frame alot.
I find nothing wrong with the treated wood as a bottom board, bees walk in and up into frames, they spend very little tme on the bottom boards anyways. I really don't see the issue against these wonderfully inovative board designs in the small to commercial bee pollination services. It is nearly perfect for what is needed of it - getting more from less is ALWAYS a good thing.
