Strain Description

Northern Lights seeds produce short, compact plants that bloom fast and abundantly. They are renowned for dense, resinous buds emitting a pungent aroma of pine, citrus, sweet spice, and earthy undertones. Effects include tranquil body relaxation paired with mild cerebral uplift—well-suited for nighttime use or stress relief.

Growing Information

Northern Lights is exceptionally beginner-friendly and performs reliably both indoors and outdoors. Flowering completes in 8–9 weeks under a 12/12 photoperiod. Grow indoors in moderate, nutrient-rich soil or hydroponics; outdoors, choose a warm, sunny site. Expect yields up to 400–500 g/m² indoors and up to 550 g per plant outdoors. Good ventilation and training (like SOG or LST) enhance airflow and minimize mold risk.

Quick Grow Tips

  • Lighting: 18/6 veg phase, switch to 12/12 for flowering; blooming completes in 7–9 weeks.
  • Nutrients: Moderate feeding; avoid excess nitrogen during flowering to maintain resin quality.
  • Watering: Keep soil moist but well-draining; avoid waterlogging.
  • Environment: Grow in climates between 70–85 °F (21–29 °C) with humidity around 40–50%; maintain airflow to prevent mold.

Summary

Northern Lights offer an easy, rewarding grow experience with compact plants, fast 8–9 week flowering, and heavy resinous yields. With moderate THC (18–22%) and sedative, euphoric qualities, this award-winning indica classic delivers a timeless relaxation and quality harvest.

⭐️⭐️⭐️⭐️⭐️
"As a producer, it was my very first year ever, so I began reading articles across the web, literally zero from the start. So most of them will have to go through several of my faults, but I still got an increase of 20 grams per crop, which made me very glad, given that I was developing with only morning sunlight on a staircase. Northern light was the only one that gave me exactly twice as much... 40 grams of exquisite citrusy marijuana fragrance. Effective, accommodating plants with hot weather and errors from newbies. Smoking is also really cool. A soft, fruity smoke that you never want to leave!"
– Timothy Atkins

    John Philips –

    Ordered 10 NL seeds reg shiping, got a 25% discount on 4/20 cause i only had a $100giftcard and cusomer service was very kind. got them in 9 days. Took 4 of the best looking seeds and put them in a cup of filtered water and set it on my router cause we’re having a cold start to summer this year and my tent wasn’t ready yet. Unfortunatly i cooked them, my bad wont do that again. Next i took the remaining 6 seeds and planted them directly in soil (pro-mix and root farm in tent) 2 sprouted on day three and another 2 that are now on day 4. One seed never stood a chance it was light green and white. After the first 4 i thought i had a bad batch, but now that i’ve seen the final germination results i know it was my mistake. 4 out of 6 is not bad. i’m happy with what i got. Thanks cropking.
