Hi Well I don't know if this is of interest, but I came accross some chinese wax foundation that had a cell size of 5.3mm!!! This is very big as far as I know. I think normal for much of the world is 5.0 (The foundation was on a candle which said made in china. Unfortunately the people who owned the candle bought it in canada, otherwise I would have bought a few to raise these big bees in!!)
