I cannot give a definite answer to this, however they certainly seem to
improve overall hive health by giving much better ventilation, since
changing to fully open mesh floors (no trays) last year, my colonies have
been larger and given a much bigger surplus.
I realise that this is only from one season, but from what I have seen I
would not go back to solid floors.
