it Is producing nectar below this temperature just less. I have hives on flowering OSR that have half a super full off nectar yesterday, that looks & smells like OSR. dont think local air temperature has been above 13 for last week, and we’ve has overnight frosts

You can see the nectar droplets in flowers, but if temp is 18C and wind, bees cannot get much honey. If flying weather rises over 20C, bees really get a good catch from flowers in one day.

One secret is that when day temp rises to 18C, that temp is only couple of hours there and bees do not have much time to work.

But you see The result, when blooming is over.

Get a balance under the hive and you see what really happens day by day. Bad thing is that the balance stops your dreaming.
