I've heard if I'm growing outdoors that I wouldn't have to worry the plants would automatically flower. But then again I've also heard something about putting trash bags on them. Which Is correct? Is the trash bag for earlier flowering? Because I'm doing an experimental grow and I have all the time in the world! Thanks!
Yes, they will flower naturally, or as you put it, automatically. If you plant them at the correct time of the season, they will flower by themselves.
