Queen Bee
Most people, Drstitson? I have never seen a post by anybody saying they leave a hole in the CB (apart from matchstick believers), nor do I know of anybody doing that - not even new beekeepers.
So you don't read the BBKA forum?
Over there, a published author writes -
This is a regular topic. Quite frankly I don't think it matters much. I like leaving one hole in the crownboard open with no insulation.
