I've grown Afghani and Northern lights outside before. They both grew surprisingly well, the rain or cold did not stop them. The Afghans turned a weird purple colour because of the cold. I also grew skunk #1 but with it being sativa dominant it did not do very well at all. It was nowhere near maturity when it started going mouldy. It was mostly stems anyway and about 6 feet tall; it couldn't cope with the low light levels.
