Just looking for peoples opinions here about the Bee hive entrance, you know the one on the landing board.

We normally make them 10mm high which is 0.40 inches, this is around about the Bee Space measurements and the Bees don't seem to mind.

But I see in some plans that the size is listed at inches which is 19mm in New Zealand talk.

What do you use for the measurements and do you know what the larger size provides the Bees?

We use screen bottom boards so ventilation shouldn’t be an issue.

We would be keen to get other peoples thoughts.
