I think most people are missing the point of autos or C. Ruderalis.. Its supposed to be grown outside, and in my case where I'm above 61 degrees latitude, the day and night hours aren't symmetrical, its absolute insanity to treat these plant like photoperiod plants. In my case ruderalis is workable in a greenhouse outside, I wont need a light depro greenhouse either. Another advantage is the light feed strategy for these auto's.
I think its the cheapest and easiest weed to grow, but its stupid how much people put time and effort into an average cultivar.
I would grow a few near a window for seeds and then transition to an outdoor grow with my seeds,
