How to Grow Narkosis

Narkosis is a fast, productive, indica-dominant feminized strain that crosses Critical with Somango. It is a 60/40 indica with a medium 18% THC, an earthy, fruity and herbal flavor, and a creative, euphoric, uplifted effect. Quick to finish and easy to grow, it is one of the more beginner-friendly plants in the catalog, with a generous harvest to match.

As a feminized strain, Narkosis produces only female, flower-bearing plants, so you can skip sexing and remove the guesswork of sorting out males. Every seed goes toward productive, bud-growing plants from the start. You grow it under long days through its vegetative stage, then switch the lights to 12/12 to trigger flowering, which gives you full control over the plant’s final size and its timing.

Easy, fast and rewarding, Narkosis is a great first grow. You can see the full genetics and buy Narkosis seeds on the strain page, and browse the rest of our feminized seeds alongside it.

Growing a Feminized Strain

Narkosis is a photoperiod feminized strain, which means it flowers in response to the light cycle rather than its age. You keep it under long days, usually 18 hours of light, for as long as you want it to grow and build structure, then switch to 12 hours of light and 12 hours of darkness (12/12) to tell the plant to start flowering. Because every seed grows into a female, there are no males to find and remove, so your whole crop goes toward buds.

That control over timing matters with Narkosis, which can stretch to a tall 3 m. Flip it to 12/12 once it has filled your space to keep the final height in check, and use the vegetative stage to top and train it. Despite its size it is forgiving and fast, finishing in just 7 to 9 weeks of flower, which is a big part of why it suits newer growers so well.

Climate and Where to Grow It

Narkosis favors a warm, tropical climate and does well both indoors and outdoors where it gets plenty of light and warmth. Thanks to its quick cycle, outdoors in the Northern Hemisphere it finishes early, around September, before the wetter autumn weather sets in. At up to 3 m it is a tall plant, so give it headroom in a tent or let it stretch outside.

Its yield is high, around 550 g/m² indoors in an optimized setup and a generous 550-700 g per plant outdoors, so it produces heavily for how fast and easy it is. As a sturdy, forgiving indica with Critical’s skunk heritage behind it, it sits among our skunk strains, and its easy, quick nature puts it right among our best seeds for beginners.

That character comes straight from its parents: Critical brings the heavy yield, fast finish and skunky backbone, while Somango adds a sweet, tropical, mango-like fruitiness. Keep temperatures around 68-80°F (20-27°C) and humidity sensible through flowering, easing it down as the dense buds fill out so they ripen clean.

Feeding Schedule (EC Guide)

Narkosis is a big, vigorous, productive plant, so feed it steadily but build the nutrients gradually rather than pushing it hard early. Start light while it is young, build through the vegetative stage, shift toward phosphorus and potassium once it flips into flower, then flush at the end so the earthy, fruity notes come through clean. The ranges below are a starting guide; adjust to your water and medium.

StageEC (mS/cm)Notes
Seedling0.5-0.7Very light feed while roots establish
Vegetative1.2-1.6Raise nitrogen as the big frame develops
Early flower1.4-1.7Shift toward bloom nutrients (P and K)
Full flower1.6-1.9Peak bloom feed while the buds swell
Flush0.0-0.4Plain water for the final 1-2 weeks

Flowering and Harvest

Once you flip it to 12/12, Narkosis finishes fast, in just 7 to 9 weeks, which is quick for such a productive plant and a real advantage for newer growers. It builds dense, resinous buds on a tall frame, developing an earthy, fruity, herbal aroma as it ripens. That speedy finish also makes it a strong outdoor choice, coming down early before the autumn damp.

Yields are high at around 550 g/m² indoors and a generous 550-700 g per plant outdoors. Keep the tall colas supported and the canopy open so light reaches the lower buds, feed it steadily through flower, and harvest when most of the trichomes have turned cloudy with a few amber for the fullest earthy, fruity flavor and the most rounded effect.

Drying and Curing

Dry whole plants or branches in a dark room at around 60°F (15-18°C) and 55-60% humidity for 7-14 days, until the thin stems snap rather than bend. A slow, even dry matters with such dense, resinous buds, because they can stay damp in the middle while the outside dries, and a gentle dry protects the earthy, fruity, herbal aroma that defines the strain.

Then cure the trimmed buds in sealed jars, burping them daily for the first week and letting them settle for three to four weeks. A proper cure is what brings out the sweet, tropical, fruity notes from its Somango side and smooths the smoke, turning a freshly dried harvest into the rich, flavorful result Narkosis is known for.

What to Do With Your Trim

Don’t bin the sugar leaves you remove while manicuring. Narkosis is a resinous plant, and with such a big harvest there is plenty of trim, so it is well worth saving for dry sift, bubble hash or rosin. That resin and earthy, fruity aroma make the trim genuinely valuable, turning a mountain of offcuts into a flavorful concentrate run rather than waste.

Flavor and Terpenes

Narkosis leads with an earthy, herbal flavor lifted by a sweet, tropical fruitiness from its Somango side, a grounded profile with a juicy twist. It is a smooth, natural-tasting smoke that balances Critical’s earthy depth with Somango’s mango-like sweetness, and a good cure brings that earthy-and-fruity character forward on the inhale.

Its terpene profile shapes that flavor. Terpinolene brings a fresh, herbal, lightly piney brightness, while alpha-pinene adds a crisp, pine-sharp lift. Humulene forms an earthy, hoppy base and linalool a soft, floral sweetness. Together these four terpenes give Narkosis its earthy, herbal, subtly fruity character with a clean, fresh edge.

Effects and Best Use

With its medium 18% THC and 60/40 indica-leaning make-up, Narkosis delivers a bright, balanced experience. It is reported as creative, euphoric and uplifted, pairing an energetic, inspired head with an easy, comfortable body, which makes it a versatile strain for daytime and creative use. The moderate potency keeps it approachable and easy to enjoy, which suits newer smokers well.

That creative, euphoric, uplifted profile makes it a rewarding strain for creative projects or an active afternoon, alongside its earthy, fruity flavor. The combination of a fast, high-yielding, beginner-friendly grow and a bright, inspiring effect is exactly why Narkosis stands out among feminized strains.

Common Problems and Pro Tips

Narkosis is forgiving and genuinely beginner-friendly, but its height is the one thing to plan for. It can reach 3 m, so indoors you need headroom and a strategy: flip to 12/12 once it fills your space, top it during veg, and use low-stress training to spread the canopy and keep the many tops level. Outdoors, simply give it room to stretch.

Its fast 7 to 9 week flowering is a real advantage, but it means you should have your training done early, while the plant is still in vegetative growth. Keep the air moving around its dense, resinous buds and ease the humidity down as the flowers fill out, and support the taller branches as the colas get heavy toward the end.

As a pro tip, lean into what makes Narkosis easy and productive: get your height management done early, feed it steadily through a quick bloom, and harvest on time to take advantage of its early, pre-autumn finish outdoors. Protect the fruity flavor with a proper plain-water flush and a full three to four week cure, and save the generous trim for concentrates.
