When the flow frames are drained of honey, as the caps are not disturbed or broken, how do the bees know to refill the frames? Or do the have to be uncapped in order for the bees to reuse them?

Since bees at the height of the season will be working on empty frames and full ones at the same time. Does this mean that it wouldn't be possible only to use the flow system?

I ordered the full give but forgot to add the shipping costs, how can I do that now and tie it up with the original order?

Would you consider a version for a national hive ethic is the most common in the uk?
