Plant it in the ground and tie it down cause I have a feeling you'll be waiting until mid Autumn before it starts to flower. I could be wrong but from my experience growing outdoors in Aust is that it won't finish until April, May, June area. I planted one around Sept and it turned into a monster! Others were planted in Jan.
Weird looking strain by the way. If it doesn't turn out to be male then I think you have more of a sativa type strain on your hands.
What you could do is keep it in a pot and keep it inside in pitch black until 8am, take it outside then bring it back into darkness at 8pm. This way you could be finished by some time in Feb.
