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

  1. Avatar for Buzzy

    Buzzy –

    Started from seed May 15th and lots of buds all over the plants within 8 weeks from start. Ordered 5 seeds and all sprouted. All plants are over 2 feet tall. Grown outdoors the entire time on Vancouver Island, BC. I’m sure if grown indoors under controlled settings they would be bigger. This is my first time growing. Couldn’t have been easier. Just ordered Revolver Autoflower seeds and again all 5 sprouted. Hoping to pull two rounds down this summer. Will definitely be ordering more seeds from these guys. Follow the germination process and no issues.

    Customer –

    2 x 100 watt cob LEDs, 3 gallon smartpots with roots organic soil…using fox farm trio at 1/2 strength which slightly burned tips but otherwise plants love it…9 weeks from seed now, expecting at least 2 oz dried bud and they’re super dense… this is my third round with these seeds, and the last of the 14 they sent me. All but one sprouted. No problems whatsoever! Northern Lights Auto is a definite no brainer!

  4. Avatar for Lyle Shaw

    Lyle Shaw –

    I should clarify 2 oz dried bud off one NLA… it has both 100 watt cobs to itself… could possibly be closer to 2.5 oz.

  5. Avatar for RC

    RC –

    Only 3 of the 5 germinate and 2 got eaten by a kangaroo, so I was left with one very strong plant which I put into a small greenhouse. The plant ended up yielding about an ounce and a half, the smoke was among the the best I have seen in many years, some friends actually decided to sit out halfway through a bowl because they “felt they had enough for now”.
