Growing Auto Northern Lights XXL: what to expect
Because Auto Northern Lights XXL 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 Auto Northern Lights 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.
