ive grown lowryder 2 and the auto ak47 outdoors. and they did pretty well. i tried to start them early as possible outdoors because the earlier in the season there is more sunlight/longer days and autos love light as do any plant especially them. ive heard of people growing them under 24 light indoor.. but the auto ak47 produced pretty well i think i got 2 and a half zips off my best outdoor one
