I'm from Winmalee and also have the Flow hives. You must be VERY patient with the flow super, I've had mine on a double brood box which is bursting with bees for about 3 weeks now. From day 1 of installing my flow super, I have always had thousands of bees working the flow super and only yesterday, after looking through the inspection window on the outer frame, noticed that they are finally sealing the gap of the split plastic combs with wax.
I'd be happy to get my first flow extraction after 6 weeks of having the super on. I would suspect that it may take you longer because of the cooler climate up the mountain.
How long has it been taking flowhive owners in the first year before they can do their first extraction ?
For a real hands on total bee experience, should consider coming down to one of our Nepean Beekeeper Association meetings held at Emu Plains High school on the second Sunday of the month. Plenty of people from up your way attend.
