Northern Light Auto takes one of the most iconic indoor strains of all time and gives it a modern autoflower twist. Bred from Northern Light x Ruderalis, this 80% indica / 20% ruderalis cultivar keeps the sweet flavour and relaxing effects of the original Northern Lights, while adding faster turnaround and simple, no-fuss cultivation.

 

As an autoflowering and feminized strain, Northern Light Auto is ideal for discreet indoor setups and high-volume outdoor runs. After a short veg phase, she quickly shifts into heavy flower production, completing her entire life cycle in roughly 10–12 weeks from sprout. Indoors, plants reach 3–4 ft and can deliver around 18–19 oz/m²; outdoors, in long-summer climates, expect 4–5 ft plants and about 6–8 oz per plant—exceptional for an auto.

 

With around 14% THC and low CBD, Northern Light Auto offers a comfortable, clear, and gently uplifting effect paired with classic indica body relaxation. It’s a smoother, more manageable version of the original—great for any time you want to unwind without getting overwhelmed. Flavours follow the Northern Lights tradition: sweet and fruity with layers of citrus, pine, earth, pepper, and a touch of classic hashy depth.

 

If you love the idea of a legendary strain in a fast, easy, and surprisingly high-yielding auto format, Northern Light Auto belongs in your rotation.
