A couple of good outdoor strains that are hardy and very resistent to many of natures curveballs are Durban Poison and Skunk #1. Both of these plants do very well outdoors and give very good yeilds with similare quality. As for the Northern Lights mentioned earlier, I wouldn't suggest it. NL is a mostly indoor strain that will have trouble reaching full potential in the rigourous outdoors. Many seed companies have compatibility ratings for indoor v. outdoor with the seeds they sell. Mandala has some very good genetics and most of their varieties do very well outdoors and they are cheap to boot.
