First question. I thought any condensation might have been dissipated by the the open mesh floor or does it lie on the under side of the crownboard.
Second question. Would it be worth leaving the main central hole in the crown board uncovered and opening up a couple of the vent holes in the Abelo roof. The OMF floor has a tight fitting under tray but there’ll be some draught from the entrance. Our winters are long and damp but I would rather not create a wind tunnel if it’s not necessary.
Condensation occurs where damp air meets cold, (on the inside of a single glazed window in winter for example) so I would be inclined to seal up and insulate the top of the hive so there are no cold spots and leave the OMF open. If it's windy, a super under the brood box would act as a baffle and stop the wind from whistling around the inside of the hive.
