it sounds like you grow outdoors, but i was going to suggest to maybe try it indoors and do a 12 / 12 from seed on it.. can't believe i'm saying this as i'm no fan of 12 / 12 grows, lol, but if ever a strain was made for that style of grow, it's a heavy sativa like what you're talking about..
i'd say give it a whirl as well, just make sure that you plant something else along with it in case it's either bunk, or doesn't finish any where near in time for your area..
