White Widow Auto Seeds by Seed Stockers – Legendary Resin Production & Balanced Effects

White Widow Auto seeds by Seed Stockers bring the legendary potency and resin production of the original White Widow into a fast, beginner-friendly autoflowering format, delivering up to 500g/m² of frost-covered buds in just 10 weeks.

Struggling with weak yields and lackluster resin?

Many autoflowering strains promise big results but fall short—small buds, low trichome coverage, and forgettable effects. You end up with a harvest that looks and feels mediocre, no matter how hard you try.

Why settle for average when you can grow a legend?

Without the right genetics, you’re wasting time, space, and nutrients on plants that don’t deliver. The frustration of low potency, poor resin, or mold-prone buds can kill your motivation. And if you’re making extracts, weak material means weak results.

White Widow Auto delivers legendary quality, simplified

Thanks to its Original White Widow genetics, this autoflower packs THC up to 23% and coats every bud in resin—perfect for potent smoke or high-yield extractions. It’s resilient, grows well in coco or soil, and thrives both indoors and outdoors, even in cooler climates. With compact size and a 10-week cycle, it’s ideal for stealth grows or quick turnarounds.

What this strain brings to your grow from day one

From the first sprout, White Widow Auto sets itself apart. You’ll see dense, resinous growth with minimal effort. Its balanced indica-sativa effect gives you clarity followed by deep relaxation—perfect for unwinding without couch-lock. Whether you're a first-time grower or a seasoned extractor, this strain pays off in quality, not just quantity.

Compact size, massive resin production

White Widow Auto stays manageable at 0.70–1.10 m (2.30–3.61 ft) indoors, making it perfect for small spaces or stealth setups. Despite its size, it produces big yields thanks to its dense, trichome-rich buds. The plant develops even internodal spacing and a strong central cola, responding well to light training like LST. Its resistance to mold and pests means fewer surprises, especially in humid or cooler outdoor conditions.

Pro tips to stretch your harvest further

Get the most out of your White Widow Auto without overspending. Use a 20L pot for optimal root development and avoid overwatering—this strain prefers a dry-to-the-touch substrate between waterings. Train gently with low-stress techniques to open up bud sites, but avoid topping. For maximum resin, consider adding Bio Bloom by BioBizz in mid-flowering to boost trichome production. Outdoors, plant late spring to early summer for best results.

Frequently Asked Questions

How long does White Widow Auto take from seed to harvest?

Approximately 10 weeks, regardless of light cycle. Some phenos may finish slightly earlier or later, but 70 days is typical.

How often should I replace my nutrient solution when growing this strain?

Every 7–10 days indoors. Outdoors, water when the top layer of soil is dry. Always check pH (5.8–6.2 for coco, 6.0–6.5 for soil) to avoid deficiencies.

Is this strain worth restocking regularly?

Absolutely. Its reliability, high yield, and legendary status make it a staple for growers. Many return to it again and again for consistent results.

Does it require a carbon filter indoors?

Yes. White Widow Auto has a strong, pungent aroma—especially in late flowering. A carbon filter like those in THC Guerilla Grow odor control solutions is highly recommended for discreet grows.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown photoperiod White Widow for years, so when I tried Seed Stockers’ autoflower version, I was skeptical. But after harvest, I was blown away—same frosty buds, similar potency, and ready in 10 weeks. I ran two grows back-to-back in 20L pots with coco and Fish Mix by BioBizz, and both yielded over 450g/m². The smell is intense, no doubt, but the trade-off is worth it. For beginners or anyone wanting a fast, high-quality harvest, this is a no-brainer. My only tip? Don’t overfeed—she’s sensitive to nutrients, so go light and ramp up slowly.

How to grow White Widow Auto seeds – Expert grow guide

Quick overview: Autoflowering · Seed Stockers · 70-day cycle · beginner-friendly · ideal for indoor and outdoor setups.

Safe start: Germinate in a moist, dark environment at 22–25 °C.

• Use jiffy pellets or paper towel method for high success.
• Transplant when the taproot is 1–2 cm long.
• Handle gently to avoid root stress.
• Start with a 7L pot if pre-growing, but plan for final 18–27L.
• RootFast by Atami boosts early root development and resilience.

Stable seedling: Keep humidity high and light moderate.

• Maintain 60–70% RH in the first week.
• Use soft lighting (CFL or low-power LED) to avoid stress.
• Water lightly—let top layer dry between irrigations.
• Introduce mild nutrients after 2–3 sets of true leaves.
• Consider mycorrhizae to strengthen root zone.

Directed growth: Optimize environment for compact, strong structure.

• Move to final 18–27L pot early—autos hate being repotted.
• Use airy soil or coco with good drainage.
• Apply Fish Mix by BioBizz for steady nitrogen and microbial life.
• Train with LST to expose lower colas.
• Avoid topping—autos can’t recover from stress like photoperiods.

Efficient flowering: Focus on resin and density in the final stretch.

• Lower RH to 40–50% to prevent mold.
• Ensure strong airflow around buds.
• Switch to bloom-focused nutrients after week 3.
• Add Bio Bloom by BioBizz to fuel trichome production.
• Monitor trichomes—harvest when mostly milky for balanced effect.

Harvest, drying and curing: Lock in flavor and potency.

• Flush 7–10 days before harvest to clear excess nutrients.
• Cut branches and hang upside down in a dark room.
• Dry at 18–22 °C and 50–60% RH for 7–10 days.
• Cure in jars, opening daily for the first week.
• Wait 2–4 weeks for smoother, more flavorful smoke.
