Why you should buy Northern Lights Auto seeds
Northern Lights Auto doesn’t need an introduction. It’s that quiet, dependable strain that’s been showing up for decades and still somehow feels underrated. Ask any old-school grower what got them hooked, and chances are this one pops up. And now, with the autoflower twist, it’s even easier to get those nostalgic, knockout buds without messing around with light cycles or overly fussy plants.
You want something easy, fast, and deeply satisfying? Something you can plant and more or less count on to handle itself? This is it. No drama. No divas. Just pure, sticky comfort wrapped in piney sweetness. Perfect for a laid-back first grow or a reliable corner strain in a more crowded tent.
If you enjoy dialing things in and maximizing every detail, the Northern Lights photoperiod version gives you more to work with.
Strain Overview
Origin
Northern Lights Auto is what happens when you take one of the most iconic indica strains in the world and give it a Ruderalis kick. The original Northern Lights was already famous for its short stature, heavy resin, and couch-lock calm. This auto version keeps all that, just trimmed down and made a whole lot easier to manage.
No need to chase photoperiod perfection here. It doesn’t care if your timer's off or the sun’s confused. Once it’s ready, it just goes. And once it’s done, you’ll understand why it’s still a go-to, even with all the flashy hybrids out there.
Effects & Flavors
This one doesn’t mess about. It leans heavy on the body: relaxing, grounding, and just plain soothing. It starts with a mellow grin, moves into that warm-limbed heaviness, and finishes with a subtle nudge toward the pillow. It’s classic end-of-day weed. You’ll probably get hungry. You’ll definitely feel good. And if you overdo it, well, you’ll wake up refreshed.
Flavors are where it gets really familiar. There’s pine, sweetness, a bit of citrus peel, and that old earthy base that just smells like real weed. Nothing artificial. Nothing weird. Just simple, resin-rich aroma that hits the nose right. The smoke? Smooth, balanced, and unmistakably indica.
THC & CBD Levels
With 18% THC, Northern Lights Auto isn’t looking to blow your head off, but it absolutely knows how to take the edge off. It’s potent enough to be felt after just a few puffs, but mellow enough to keep things grounded. CBD levels sit low at 0.2%, which is exactly how this strain has always rolled. Clear-headed, body-forward, and full of good vibes.
Terpenes
If you’ve been around the block, the terp profile here is going to feel like a familiar handshake. Terpinolene and both alpha- and beta-pinene bring in that forest-floor freshness, while beta-caryophyllene adds just a touch of spice around the edges. There’s linalool for calm, limonene for a little citrus lift, and humulene to round it out with a mild, almost hoppy bitterness.
It's not flashy. It’s just right. Like old records or cast-iron pans, it works because it’s stood the test of time.
Growing Northern Lights Auto Seeds
Grow Difficulty
This is one of those strains that makes you look like you know what you’re doing, even if it’s your first grow. It’s forgiving, sturdy, and not too fussy about mistakes. Feed it decently, give it light, keep the humidity reasonable, and it’ll reward you with chunky, crystal-covered buds every time.
Great for beginners. Still satisfying for the pros. No ego. Just results.
Indoor vs. Outdoor Growing
She stays compact indoors, usually around 28 inch to 47 inch, making her a good fit for tents, closets, or discreet corner grows. Outdoors, she stretches a bit more, up to 67 inch when she’s feeling herself, usually somewhere between 47 inch and 67 inch depending on environment. She handles a wide range of climates too, from warm Mediterranean zones to cooler, less predictable ones.
This is the kind of plant you can run almost anywhere without a fight. Whether it’s greenhouse, balcony, or back garden, she’s pretty chill about her surroundings.
Flowering Time & Yield
Northern Lights Auto finishes up in about 63 to 70 days from seed. That’s quick, especially for the kind of quality she throws out. Indoor growers can expect a solid 1.3–1.6 oz per square feet, while outdoors you’re looking at 2.1–5.3 oz per plant, depending on how much sun and love she gets.
Not the highest yields on Earth, sure. But for the size, effort, and reliability, she holds her own. Plus, the bud quality? That’s the real win.

Bought some of these seeds as well as some granddaddy purple and godfather OG. Planted 2 seeds of each and everything has came up nicely! and about four weeks after planting the seeds they all have nice 5 to 7 prong leaves. A couple more weeks in veg and I’ll move all these ladies to flower for about 8 weeks. Total Cicle about 14 weeks from putting the seed in soil to harvest.

Just smoked some I grew from a free seed from WSE. I wasn't expecting much b/c I'm an old chronic toker, but I got pretty high and relaxed, and I just started another one. I could have done a better job at growing it, I only used a 1qt container. The buds were nice and tight and stinky, and took about 13 wks. I thought it tasted like skunk mixed with some kind of fuel.
