Thanks for the comments. It is interesting to see the different approaches. I’m currently going to stay with my original aim and check the hive in a week or two and decide whether or not to increase the opening or leave it significantly reduced.
Based on my last inspection I’m actually anticipating another harvest from my full-flow super while still leaving a full hybrid super for winter. The weather here is still warm-ish during the day (http://www.bom.gov.au/wa/forecasts/perth.shtml) and expected to remain like this for a while, even though it is reasonably cool of a night (it’s all relative I guess…). As commented by others in the forum thread for Perth we are experiencing a second round of flowering for many of the eucalypts
