Make sure if you get autos that they have high THC contents. I found some at dinafem that had a high content. Most autos are runderalis and have low THC like 10, 11 percent. But those are easy I guess. I just have a light timer set to 18/6 it cost like 3 bucks. I can choose when I want mine to flower , I could flower from seed. I can choose how tall my plant gets though , just by pushing a button on my 3 dollar timer.
