Thats the trouble with tassie our light cycle is so long over summer that they finish latter than the mainland states.
My couple outdoors have around 4 weeks to go, maybe 5.
It's not day length that has the desired effect on flowering. The hormone trigger is set off by the dark cycle.
At greater distances from the Equator, maximum daylength is longer. Therefore the days are too long to trigger flowering until much closer to the equinox, I believe.
I hypothesize that it only takes 11 hours of darkness to trigger flowering, as most Cannabis I have ever seen is in bloom PRIOR to the equinox.
It would be well worth an experiment with indoor growing to find what the true dark cycle trigger length is (for a specific varietal) . There could be numerous advantages to longer light cycle during flower cycle.
As for me, I have put a few smaller NL5H's out and they're only a couple of weeks into bloom.
