I'd use kc-33or 36 outside as well, but would have other strains too. Other strains will survive like skunk 1 and northern lights hybrids. At least for me in the bootheel area of Missouri which is roughly a similar area. I'd like to cross kc=33 with c99 because it is an earlier finisher that did well for me outdoors.
When did KC33 finish for you? I'm at a similar latitude and I had to harvest on 9/26, and they looked like they needed until at least October 10th
