Ace Seeds doesn’t cut corners-especially on landrace-based work. Malawi x NL Auto brings Old Killer Malawi’s electric head to an autoflower clock, tempered by Northern Lights’ calm, compact build. Expect a sativa-dominant ride, THC in the 10–15% zone, and a clean, happy high that doesn’t bulldoze your day.
After selling thousands of packs and walking hundreds of trade show aisles, this is one I recommend when you want reliable vigor and classic character in an auto.
This cross fuses two proven pillars: Old Killer Malawi and an autoflowering Northern Lights. The Malawi contributes the signature soaring clarity, stacked calyxes, and a spicy-citrus edge. Northern Lights brings the auto trigger, tighter internodes, and the chill that keeps the high friendly rather than frantic.
Ace Seeds selected toward dependable timing and a balanced effect curve-uplifting upfront, smooth on the exit. You get lane discipline without losing soul.
The lead note is bright, fruity sweetness with a floral lift. Think ripe mango meets wildflowers, backed by a mellow herbal finish. It’s not loud-for-loud’s-sake-just clean, layered, and pleasant in the jar.
Onset is quick: a gentle lift behind the eyes, mood up, motivation up. No rollercoaster, no couch anchor. The middle ride stays happy and focused; the tail coasts into relaxed, easy conversation.
Expect two main lanes, plus a blended middle-nothing wild, thanks to the F4 work.
Resin is consistent for the potency range; Malawi-leaners may sparkle earlier. Pheno hunters will enjoy picking their favorite terp lane without babysitting weird outliers.
Skill level: intermediate. It’s an auto-so your timing and environment matter. Set it right from day one.
Timeline: seed to harvest in 8–12 weeks. Indoors, expect average yields-think 60–120g per plant with good dial-in, or 350–450g/m² in optimized rooms. Outdoors in warm seasons, place in full sun early and protect from heavy rain late.
Riley, first-time auto grower: “Two medium plants, 85 days seed to chop, sweet-floral nose. Easy LST, no drama. Smooth, happy daytime smoke that didn’t hijack my schedule.”
Jess, seasoned indoor grower: “Malawi-leaner went taller but stacked nice. 420 g/m² under LED at 20/4. Clean uplift, zero jitters. Would run again.”
Old-school Malawi spirit, Northern Lights discipline, and an autoflower calendar. Ace Seeds keeps it tight; drops don’t linger. If you want a sativa-forward auto that finishes fast and smokes friendly, grab the 5-pack while it’s still warm.

How long from seed to harvest?
Typically 8–12 weeks, depending on environment, phenotype, and light intensity. Most growers see faster finishes under strong, consistent lighting and steady temperatures. Outdoor runs in cooler seasons usually push toward the longer end of that window.
What light schedule works best?
Autos thrive at 18/6 or 20/4 from sprout to chop. Pick one and keep it consistent. More light hours can speed growth, but watch heat and VPD so you don’t trade speed for stress.
Is this strain good for beginners?
It’s rated intermediate. If you’ve completed a couple grows and can manage watering, light distance, and gentle training, you’ll be fine. Total first-timers can still succeed by keeping it simple and avoiding heavy hands.
How tall does Malawi x NL Auto get?
Medium height for an auto. Malawi-leaners stretch more; NL-leaners stay compact. Plan 24–36 inches indoors with proper light. Use early LST to keep an even canopy without cutting off the main engine.
What yield should I expect?
Average yields with good dial-in. Indoors, 60–120g per plant is common; optimized rooms can reach 350–450g/m². Outdoors, sun and season matter-earlier starts and full exposure help a lot.
What does it smell like while growing?
Fruity-floral with a sweet edge, moderate intensity. Not a skunk bomb, but you’ll notice it in late flower. A decent carbon filter will keep the nose polite in apartments and small spaces.
Can I top this autoflower?
You can, but it’s risky on autos. Better play: gentle LST starting week two to three. Bend, don’t break. You’ll keep momentum, widen the canopy, and avoid stunting your timeline.
Indoor or outdoor preference?
Works in both. Indoors gives precise control and repeatable finishes. Outdoors, target warm, bright months, protect from heavy late-season rain, and use final containers from the start to prevent slowdown.
What nutrients does it like?
Moderate feed, steady calcium and magnesium, and reduced nitrogen after week four. In coco, maintain consistent EC and don’t let pH drift. Overfeeding is the usual way to turn a smooth run into a headache.
How’s the high for daytime?
Friendly and functional. Uplifting, happy, and social without a buzzy edge. It’s the coffee-break sativa vibe-motivating but not jittery-then a smooth landing that lets you carry on with real life.
