I maxed out with my equipment last year, by late July everything I had was on the hives. It worked out, got all the frames of foundation drawn out and filled during the flow, just had to muscle around some full deeps instead of shallows. I'm not planning any expansion this year, six good hives is all I have time and room for. Built a few more boxes to replace some that are just about rotted out but I'm not even looking for any swarms this year.
