First, the full admission: I'm with the I-don't-mess-with-autos crowd. Mostly because I can't imagine potency comes very close to that of photos. Secondly because we see a lot of sickly-looking autos on this site.
I used to live in Greenville, NC. The best outdoor year I had was using a UK Cheese x C99 clone (this was a cross known as Chucky's Bride). She had plenty of preflowers when I put her out there. She was done in early September. Buds were rock-hard and the potency was supreme.
Can you at least start plants indoors? If so, I would find a few photos with 8 - 9 week flowering times.
