One Flow Super per hive is the simple answer, as you can keep harvesting the honey whenever it is ready, giving the bees room to keep working and making more honey.
However, if you live in areas with a very high nectar flow, or if your existing bee colony is particularly large, we would recommend you use two Flow Supers or more. You can also add conventional supers for overwintering purposes. As the Flow Hive is a new innovation, we’re interested in your feedback as to how many Flow Supers are best in your situation.
