Auto Northern Lights – strain profile

Genetics and history

Northern Lights is probably the most renowned indica strain of all time. The original line emerged in the 1980s on the US Pacific coast through selection of Afghan and Thai landraces, with the Northern Lights #5 clone line becoming a global standard for indica quality. The autoflowering version crosses this clone line with ruderalis genetics – the result is a more compact and faster plant that retains the characteristic aromatic and effect properties of the original.

Northern Lights has won countless awards at Cannabis Cups and sits in the genetic foundation of dozens of other famous strains – Super Silver Haze, Shiva Skunk, and Jack Herer were all created with its contribution.

Growing tips

Auto Northern Lights rightfully ranks among the most beginner-friendly autoflower strains. Plants remain compact (60–90 cm), produce minimal odor during the vegetative phase, and are naturally resistant to mold, pests, and temperature fluctuations – a trait inherited from Afghan ancestors.

From seed to harvest requires only 9–10 weeks. A light schedule of 20/4 ensures optimal balance between photosynthesis and regeneration. We recommend a lightly organic substrate with naturally balanced pH (6.0–7.0) – this strain doesn't respond well to overfeeding, so start nutrient dosing at 50% of recommended values. LST (Low Stress Training) applied in the third week can increase yields by 20–30% without risking plant stress.

Effects and medicinal use

Auto Northern Lights effects are typically indica – deep body relaxation with gentle mental calming without pronounced psychoactive stimulation. The terpene profile enriched with linalool adds lavender aromatic notes and amplifies myrcene's natural anxiolytic action.

Medicinally, it finds use especially for:
- Insomnia and sleep cycle disorders
- Chronic pain, muscle tension, and cramps
- Stress states and anxiety
- Loss of appetite and nausea induced by treatment

Auto White Widow – strain profile

Genetics and history

White Widow is a legendary hybrid strain created in the early 1990s by Dutch seedbank Green House Seeds. It arose from careful crossing of Brazilian sativa and South Indian indica. The autoflowering version integrates ruderalis genetics, yet retains the strain's most characteristic feature – an extremely dense trichome coating that gives the entire plant its characteristic frosty, white appearance and lent it its name.

White Widow dominated Dutch coffee shops throughout the 1990s and remains one of the world's best-selling strains with uninterrupted popularity to this day.

Growing tips

Auto White Widow is somewhat more nutrient-demanding than Auto NL, yet still ranks among strains suitable for growers with at least basic experience. Plants reach 70–110 cm and, due to sativa genetics, display more pronounced branching, which with proper training yields more lateral shoots with dense buds.

Seed to harvest takes 10–12 weeks – 1–2 weeks longer than NL, but the reward is significantly higher yields. The plant responds well to SOG (Sea of Green) method and light defoliation tactics in the third week of flower, which improve air circulation and light penetration to lower areas. For indoor growing, maintain temperatures of 22–26 °C and relative humidity of 40–50% during flowering – higher humidity with dense buds increases Botrytis risk.

Effects and medicinal use

Auto White Widow offers more balanced, biphasic effects than the purely indica Northern Lights. The onset brings cerebral euphoria and increased creativity combined with mental clarity, which gradually transitions to pleasant body relaxation without debilitating heaviness. Due to its hybrid nature, it can be used in afternoon and evening hours.

Medicinally, it finds use for:
- Depressive states and mood disorders
- Chronic stress and social anxiety
- Mild to moderate pain
- Physical fatigue and exhaustion – at lower doses acts stimulating

Head-to-head: who wins at what?

Speed: Auto Northern Lights – at 9–10 weeks from seed to harvest, it ranks among the fastest autoflower strains ever. Decisive advantage when planning multiple cycles per season.

Yields: Auto White Widow – larger plants with longer flowering time and more pronounced branching consistently deliver higher yields both indoors and outdoors.

Growing ease: Auto Northern Lights – remarkable resistance to care mistakes, nutrient fluctuations, and environmental stress make it ideal for your first autoflower.

THC content: Auto White Widow – with potential up to 20% THC has a measurable edge, though with optimal growing of both strains the practical difference isn't dramatic.

Flavor profile: Depends on personal preference – NL offers sweet, earthy tones with a hint of pine; WW is peppier and woodier with pronounced caryophyllene character.

Discretion: Auto Northern Lights – smaller stature and significantly lower odor production predestine it for inconspicuous growing in tight spaces.

Effects versatility: Auto White Widow – hybrid character covers a wider spectrum of situations from morning creativity to evening relaxation.

Which one for you?

Choose Auto Northern Lights if:
- You're just starting with growing and want to master basic techniques without failure risk
- You have very limited space – micro grow, grow box, or repurposed PC case
- You need discreet growing with minimal odor production
- You seek a purely relaxing, sedative strain primarily for evening use
- Priority is the shortest time to harvest

Choose Auto White Widow if:
- You have at least basic growing experience and understand plant nutrition
- You want to maximize yields and waiting an extra 1–2 weeks doesn't bother you
- You seek a versatile strain usable day and evening with variable effects onset
- You appreciate resinous buds with extraordinary trichome density
- You plan to make concentrates, rosin, or traditional hash

Frequently asked questions

What's the difference between auto and photoperiod versions of these strains?

Autoflowering versions are more compact, faster, and start flowering automatically regardless of light cycle length. They don't require switching to 12/12. Compared to photoperiod versions, they typically yield 20–30% less and have slightly lower THC content – compensation comes as significantly shorter overall cycle and easier management. Detailed comparison can be found in the article on autoflower vs feminized seeds.

How many auto plants fit on 1 m²?

For Auto Northern Lights we recommend 6–9 plants per m² due to compact stature and less pronounced branching. For Auto White Widow, count on 4–6 plants – it needs more space for natural lateral shoot development and better air circulation between buds.

Can auto strains be grown outdoors in the Czech Republic?

Yes, both strains handle Czech climate conditions reliably. Auto Northern Lights is more resistant to cooler and damper weather. Optimal is sowing in May with planned harvest in July through August. The short seed-to-harvest duration allows for two harvests per season in favorable summers.

Which is better for extract production?

Auto White Widow – its extraordinarily dense trichome coating is its genetic trademark and practical advantage for hash, bubble hash, rosin, and solvent extracts like BHO production. Auto Northern Lights with its aromatic complexity is better suited for direct consumption.

Can I grow both strains in one grow box?

Yes, both strains share similar requirements for temperature, humidity, and light spectrum. The main operational compromise is different heights at full maturity – Auto White Widow will typically be 20–30 cm taller. Place it farther from the light source or apply LST from week three of vegetation to level out the canopy height profile.
