I've grown 12 PolarLights #3 outdoors this summer. Great strain! Gets pretty large too for an auto, my biggest plant was as tall as me (185cm). Grew them in soil in 16 liter airpots, at least I think it's 16 liter, the one's with the green bottom. Some sites have them as 15 liters, some say 16. Anyway, they were big enough for the PolarLights.
Only downside is that they took a long time to finish, but I knew that from the beginning as she has a lot of Sativa genes. No mold whatsoever on these and good yield, about 65 gram on average - summer was also average, I think it could have been more with better weather. Very easy to maintain too. Will plant these again next year, only double the amount this time.
