October or November I believe. But i live in California haha! So I might be wrong...
EDIT- I found an article at CannibisCulture. Said this "Aussie growers in areas with appropriate seasonal temperature variations start their seedlings indoors in October and transplant them outside into Aussie springtime a few weeks later. They look forward to harvests beginning in March and continuing through May. Other growers are able to grow outdoors year round, reaping two to four harvests annually."
