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

    My first order was lost in the mail and CKS replaced them immediately but, the first 2 beans I’m growing from the 5 pack are not auto’s, they didn’t preflower until 8 weeks and I’m now 6 weeks into flowering, they are tall, one in coco at 27″ and one in dwc at 37″. I’ll try 2 more beans from the pack and see if those are actually autoflowers.

    New grower and decided on Crop King. Ladies on the phone are always nice pleasant and know their stuff. I ordered 10 pk of NL AF and got 12 seeds. So far my 4th grow and still going strong. So far, 100% germination success rate too… Mind you, this last grow of mine I tried something new to germ my seed and the paper towel dried out and became stiff as a rock. I stayed up all night while I soaked again then planted in a charged jiffy pod and Ill be a monkeys uncle if that didnt sprout, it is now growing bud sites and currently 8 nodes and 18 inches tall and bushed out bigger then ever… Its almost like, Crop King seeds are magic… This is coming from someone who never grown anything their entire life except maybe mold on a pizza box… Needless to say, Im a customer for life here! Not to forget, if you call in an order, the ladies truly are sweethearts…

    Loved it. One of four autoflowering varieties I grew outdoors in summer 2019 in northern Alberta. Ended up with 91 g of nice dry bud from this plant. See growdiaries.com Great smoke with classic NL aroma, taste and high.

    Kroonen –

    Extremely happy, seeds arrived in one week, only used two seeds so far but both germinated right away, i let the first one dry out by accident but my second atempt worked and the plant is almost ready to harvest. Did a indoor grow in a garage can. I will definitely be purchasing my seeds from cropking in the future. Hoping to have blue majestic seeds available in the future
