non autos... get the right genetics, you can clone and keep your favorites. Can't do that with autos. Non autos tend to be more potent as well. I really liked the plants I grew from Sannie and Mr Nice has some legendary stuff. I read nothing but good things about PeakseedsBC and will be ordering from them next. They are cheap too.
The Skunk from Peakseeds looks like it might be good in a SOG. There are some amazing plants out there for that setup. My buddy has one that grew some massive huge single colas that were dense and heavy despite huge amounts of stress (mites start to finish, kept to minimal levels). Clone only variety AFAIK, but the point is there are some incredible plants for this setup. Good luck finding one.
I've seen Critical Mass do pretty well in these setups (MNS).
