I want to add that this hive is in the city of Los Angeles on a rooftop of an apartment complex, no hive beetles yet, I do see signs of mites, but I'll let the bees handle them, since this is supposed to be VSH-Italians. The current mite count is low, so they should be just fine. The temp here stay consistent year round, the bees are out foraging all the time. I originally planned on waiting until spring to add the flow Super, but my hive is becoming honey bound, so it was a choice to add a medium or give it a try. With the recent rains there's a lot blooming here, about 75% of the returning bees are packed with pollen. Not bad for December in SoCal, now the valley where my other hives are located, they have slowed down in comparison, because to the large temp swings from day to night, I will wait until spring before adding a Flow to them.
