Growing Big Devil Auto: what to expect

Because Big Devil Auto is an autoflower it runs on age, not photoperiod: keep it under 18–20 hours of light from sprout to harvest, start in its final pot, and go easy on training after week 3 — autos never pause to recover. Growers familiar with Big Devil Auto or Ruderalis will recognize much of its behavior. Whatever the listing says, the cut in YOUR tent is the ground truth: log feedings, readings, and photos, and let the trends — not the label — drive decisions.
