Seeing your video I would suggest you make sure all your boxes are aligned with each other ,I'm sure I saw gaps between them .Nice to see the bees flying
John.
Yesterday I went to the further away apiary with my InstantVap. I've boasted before about how it does x hives in x minutes on one battery. Turns out it doesn't manage any hives if you forget to take the batteries. Job done today, in the cool misty air. What happened to the warm temps we were due?
