Northern Lights Auto by Green House Seeds – Fast Autoflowering Version of the Legendary Indica

The Northern Lights Auto by Green House Seeds is your express ticket to the legendary, soothing high of one of cannabis history's most iconic strains, without the wait. This autoflowering version condenses the classic Northern Lights experience into a rapid 10-week cycle, delivering dense, resinous buds with that unmistakable sweet, earthy, and incense-like aroma that defined a generation.

Ever feel like your growing space is on hold while you wait for a photoperiod plant to finish its long veg cycle? Or maybe you're tired of juggling light schedules and worrying about light leaks ruining months of effort. That waiting game kills the vibe and limits how many harvests you can pull in a year. Northern Lights Auto solves this by cutting straight to the chase. It flowers automatically based on age, not light cycle, meaning you can run it under a consistent 18/6 light schedule from start to finish. No more guessing, no more stress—just a predictable, fast-tracked grow that fits into any setup, anytime.

What it's like to grow and enjoy on your own

Growing Northern Lights Auto solo is a deeply satisfying, low-maintenance project. It's the perfect strain for the personal cultivator who values discretion, efficiency, and a guaranteed result. You get to witness the entire lifecycle of a cannabis legend in your own space, from a tiny seed to a frosty, aromatic plant, all within a single season. The process is straightforward, forgiving of minor mistakes, and culminates in a personal stash of top-shelf, old-school weed that's all yours.

The solo consumption experience is equally rewarding. This strain delivers a potent, full-body relaxation that melts away stress without overwhelming sedation. It's the perfect companion for a quiet evening, enhancing music, movies, or creative hobbies with a warm, euphoric glow. The flavor—a complex mix of sweet pine, earth, and spicy hash—is something to be savored slowly, making each personal session a ritual of appreciation.

What it's like when you share the harvest

Northern Lights Auto truly shines in social settings. Its generous yields mean you'll likely have plenty to share, turning you into the most popular person in the room. Passing around a jar of these dense, frosty nugs is a conversation starter, invoking nostalgia for seasoned smokers and introducing newbies to a timeless classic. The shared experience of its effects—a universally enjoyable, balanced high that promotes laughter and deep conversation—makes it a perfect social lubricant.

Whether you're rolling a fat joint for a circle or loading a vaporizer among friends, the consistent quality and recognizable aroma of Northern Lights Auto create a communal bond. It's a strain that everyone seems to know and love, making your homegrown harvest a centerpiece for connection and good times.

Tips for choosing how and with whom to use it

How to grow Northern Lights Auto

Quick Overview: A fast, forgiving autoflowering indica ideal for first-time growers or anyone wanting a reliable, heavy-yielding harvest in just 10 weeks.

Safe Start & Seedling Stage:

• Germinate seeds in a warm (22–25°C), humid environment. Soak in water or use the paper towel method.
• Plant directly into its final pot (18–27 L / 4.8–7.1 gal) to avoid transplant stress, which can stunt autos.
• Use a light, airy potting mix or coco coir to encourage rapid root development.

Vegetative & Flowering Growth:

• Run lights 18–20 hours daily throughout its entire life cycle. No need to switch to 12/12.
• Keep temperatures between 20–26°C (68–79°F) and humidity around 40–60%, lowering it as flowers develop.
• Feed with a balanced, light nutrient regimen. Autos are sensitive to overfeeding; start at half strength.
• Low-Stress Training (LST) is highly recommended to open up the canopy and increase light penetration for bigger yields. Avoid topping or aggressive pruning.

Flowering, Harvest & Cure:

• Flowering begins automatically around weeks 3–4. Watch for white pistils and bud formation.
• Support heavy branches in late flower. Maintain good airflow to prevent mold in dense buds.
• Harvest when trichomes are mostly milky with some amber for a balanced effect. Flush with plain water for 7–10 days before harvest.
• Dry slowly at 18–22°C (64–72°F) and 50–60% RH for 10–14 days, then cure in jars for at least 2–4 weeks to perfect flavor and smoothness.

Frequently Asked Questions

Is Northern Lights Auto good for beginners?

Absolutely. It's one of the best starter strains. Its autoflowering nature removes light schedule complexity, it's forgiving of minor mistakes, and it delivers a classic, high-quality result in a short time.

How much will one plant yield?

Yields vary with setup, but you can expect 100–150 g (3.5–5.3 oz) per plant outdoors in good conditions. Indoors, with optimized lighting and training, it can produce up to 800 g/m².

Can I grow it outdoors in a cooler climate?

Yes, but with caution. It needs temperatures consistently above 10°C (50°F) to thrive. In cooler climates, start it later in spring or use a greenhouse to extend the season.

What's the best way to consume it for the classic flavor?

To truly taste the sweet, earthy, hash-like notes, use a clean glass pipe or, better yet, a low-temperature vaporizer. This preserves the delicate terpenes that give Northern Lights its iconic profile.

Personal Experience of Pevgrow's CEO (Alan)

Northern Lights Auto has been a staple in my personal grows for years, and it's the strain I most often recommend to friends starting out. There's a reason it's a legend. In my tent, under a consistent 18/6 schedule with a quality LED light, it's almost robotic in its reliability. I've seen it bounce back from a slight underwatering episode without missing a beat. The structure is perfect for LST—I gently bend the main stem early on, and it responds by throwing out multiple strong colas that all fatten up beautifully.

The best part? The smell. It's not the overwhelming candy-store blast of some modern hybrids; it's a deep, comforting aroma of pine forest, damp earth, and spicy hash that fills the room during the last few weeks. When I share these buds, the reaction is always the same: "Wow, this tastes like proper old-school weed." For me, it's the perfect evening strain. It hits fast with a cerebral euphoria that quickly melts into a full-body relaxation—ideal for switching off after a long day without being completely couch-locked. It's proof you don't need a 100-day grow cycle to get exceptional quality.
