I would like to confirm these are my findings also.
- Lots of bees on the Flow™ Frames.
This is the main factor. If there are not many bees when you look in the rear window and the side window, it will probably take some time for the bees to build up and start working on the Flow™ Frames.
2 A good nectar flow.
Honey won’t be stored in your hive, regardless of the number of bees, unless there are enough flowers around with plenty of nectar.
In late Spring I had Flow Frames jam packed with bees. With two brood box’s up to speed there were wall to wall bees in the frames. However there was no honey going in. Hive numbers were stable as far as I could tell with just enough blossom about to keep the status quo.
Then 4 or 5 days ago the main forest flowering trees began to bloom.
Almost instantly I saw honey going in the frames. The rate honey is going at present I would not be surprised if the Flow frames were full and capped within two weeks.
