Auto NL Feminized Seeds by Female Seeds · Fast Autoflowering Northern Lights Genetics

The Auto NL by Female Seeds is your express ticket to the legendary Northern Lights experience, delivering the same iconic indica relaxation and resinous buds in a fast, easy-to-grow autoflowering package. This is the strain that built its reputation on powerful, body-melting effects and a sweet, earthy aroma, now adapted for modern growers who value speed and simplicity.

Are you tired of waiting months for a harvest, juggling light schedules, and worrying about male plants ruining your crop? That constant vigilance steals the joy from growing, turning a relaxing hobby into a source of stress. You end up with wasted time, wasted space, and the frustration of an inconsistent yield.

Auto NL solves this by being 100% feminized and autoflowering. It automatically switches to flowering based on age, not light cycles, eliminating the guesswork. You get guaranteed female plants and a reliable harvest in just 11-12 weeks from germination, perfect for a continuous harvest or a discreet outdoor grow. Its compact, uniform structure is tailor-made for Sea of Green (SOG) techniques, maximizing your yield in minimal space.

Before You Start Growing Auto NL

Preparation is straightforward. You'll need a well-draining, airy substrate like a light mix soil or coco coir. Autoflowers prefer not to be transplanted, so start your seeds directly in their final pots, which should be between 11–20 L (2.9–5.3 gal). Ensure your grow space is clean and your tools are ready.

• Germinate with care: Use the paper towel method or place seeds directly in moist substrate at 22–25 °C (71.6–77 °F).
• Choose the right pot: A fabric pot around 15–20 L (4–5.3 gal) is ideal for root aeration and preventing overwatering.
• Set up your environment: Have your lights ready for an 18/6 cycle and ensure good airflow from day one.
• Plan your nutrients: Have a mild, balanced fertilizer for seedlings and a bloom booster for later stages ready to go.

During the Auto NL Grow Cycle

Once sprouted, Auto NL shows vigorous, indica-dominant growth with tight internodes. It will begin its automatic flowering phase around weeks 3-4. During this time, focus on providing consistent light and avoiding any stress. Low-Stress Training (LST) is highly recommended to open up the canopy and expose more bud sites to light, but avoid topping or other high-stress techniques.

Monitor your plants for the signature resin production that starts early and coats the buds in a thick layer of crystals. The aroma will develop from a fresh, earthy scent into a stronger, sweet pine and skunky fragrance as harvest approaches.

Harvesting and Enjoying Your Auto NL

After 11-12 weeks, your Auto NL plants will be ready. Look for the pistils to darken and recede, and the trichomes to turn from clear to milky white with some amber for a more relaxing effect. The post-harvest process is crucial for flavor.

Dry your buds slowly in a dark room with 50-60% RH and 18-22 °C (64.4-71.6 °F) for about 7-10 days. Then, cure them in airtight jars, burping daily for the first two weeks. This enhances the smooth, sweet smoke and locks in the potent effects.

Frequently Asked Questions

How long does Auto NL take from seed to harvest?

Auto NL typically completes its entire life cycle in approximately 11 to 12 weeks from the day you germinate the seed. This includes both the vegetative and flowering stages, as it's an autoflowering strain.

Is Auto NL good for beginner growers?

Absolutely. Its autoflowering nature eliminates light schedule management, its feminized seeds guarantee no males, and the plant is known for being resilient and forgiving of minor mistakes. It's one of the most recommended strains for first-time growers.

Can I grow Auto NL outdoors?

Yes, Auto NL performs very well outdoors in a warm, sunny climate. It can handle some variation in weather and will finish by early to mid-autumn in the Northern Hemisphere. Expect potentially larger plants and yields compared to indoor grows.

What lighting schedule should I use for Auto NL?

Use an 18 hours on, 6 hours off (18/6) light schedule throughout its entire life. You can also run 20/4 or even 24/0, but 18/6 is the most efficient and common cycle for autoflowers.

Should I top or heavily prune Auto NL plants?

It's generally not recommended. Autoflowers have a limited time to recover from high-stress training like topping. Instead, use Low-Stress Training (LST) to bend and tie down branches. This technique is very effective for increasing yield without stunting its fast growth.

Personal Experience of Pevgrow’s CEO (Alan)

Let me tell you, Auto NL is the strain I hand to friends who say they want to try growing but are intimidated. It's the ultimate teacher. I always start them in their final pot—a 15 L (4 gal) fabric pot with a light, airy mix—and under a simple 18/6 LED schedule. The growth is so predictable; you see the pre-flowers around week 3 and know exactly what's coming next.

My pro-tip is to go light on the nutrients, especially nitrogen, in the first few weeks. This girl has a hearty appetite during flowering, but she's sensitive early on. I like to introduce a bloom booster like PK 13/14 around week 5-6, and that's when the buds really start to stack and frost up. The smell in the tent during the last three weeks is pure classic cannabis: earthy, skunky, with that sweet pine backbone. It's not overly loud, but a carbon filter is still a wise investment.

The best part? The effect is exactly what you hope for from a Northern Lights. It's not a racy, paranoid high. It's a warm, heavy blanket that starts behind the eyes and spreads down through your shoulders. Perfect for melting away the day's stress. For yield, don't expect monster colas, but the plant produces solid, dense nuggets coated in resin. In a SOG setup with 9 plants per square meter, you'll be very happy with the results. It's a reliable workhorse that never lets you down.
