I'm new to beekeeping and have a question. My latest empty supers were added 3 weeks ago (foundation-less frames with no drawn comb). I added supers when the supers under them were 100% full of capped honey. I inspected the hives 2 days ago and they haven't touched the new supers. Does that mean the flow is over? Wouldn't they still make honey with all of the white clover and other flowers still abundant? Should I take the empty supers off or leave them? Also, the heat index is suppose to reach 105 today. Do you do anything extra for the bees when temps are in triple digits like take the outer cover off for better ventilation? This pic was taken yesterday and it wasn't as hot as today.
