My good friend grew plants outdoors in a shed in Aberdeen through winter, harvested early feb. The strains were Blue Cheese, Jamaican Dream and Jamaican dream X's, not autos but maybe you could get auto equivalents? Jamaican dream is supposedly a poor yeilder in cold weather yet still produced good buds in extremely cold weather so I wouldn't worry too much. A good fungal resistant strain would be a good idea maybe? I heard Dutch passion is a good outdoor variety. I'm a complete novice at this ngl and i have no experience with autos AT ALL so just food for thought really :L
