White Widow Automatic by Royal Queen Seeds delivers the legendary potency and resin of a cannabis classic in a fast, beginner-friendly autoflower that’s ready to harvest in just 75–85 days.

Are you tired of complicated grows that demand constant attention and perfect conditions?

It’s frustrating when your setup feels like a science lab instead of a chill hobby. You want something reliable—something that grows strong without needing PhD-level skills or a jungle of gear.

White Widow Automatic cuts through the noise. This isn’t just another auto—it’s a stabilized masterpiece that brings the world-famous White Widow experience to growers of all levels, with minimal fuss and maximum reward.

Less Equipment, More Results

White Widow Automatic thrives with a minimalist approach. Its compact size and stable genetics mean you don’t need massive tents, complex training, or a nutrient spreadsheet. This strain replaces the need for multiple finicky varieties with one resilient, high-performing plant that delivers consistent quality.

What You Can Simplify Once You Have It

With White Widow Automatic at the core of your grow, you can streamline your entire process. No more juggling multiple strains with different needs—just one proven performer that handles stress, climate shifts, and beginner mistakes like a champ.

• Stop using multiple seed types for different spaces—this one works everywhere
• Reduce your nutrient schedule—its stable genetics handle standard feeding
• Ditch the SCROG net—its bushy structure fills space naturally
• Forget topping or FIM—no need to stress the plant
• Skip the humidity controller—tolerant of mid-range RH swings
• Minimize pest treatments—naturally resistant to mold and bugs
• Eliminate light cycle timers for photoperiods—18/20h light all the way

How to Build a Minimalist Grow Setup Around This Strain

1. Start with a single 20L fabric pot per plant—no need for multiple sizes
2. Use a simple soil mix with mycorrhizae—try Worm Humus Biobizz for strong roots
3. Set up one full-spectrum LED—no need for veg and bloom switches
4. Water when topsoil is dry—no complex irrigation timers
5. Add a single bloom booster later—like Hyper Bloom Terra Aquatica for denser buds
6. Harvest at 75–85 days—no waiting, no guessing
7. Store extras in a cool, dark place—seeds last years

Frequently Asked Questions

Is White Widow Automatic good for beginners?

Yes. Its stable genetics, mold resistance, and forgiving nature make it perfect for first-time growers. Just keep light, water, and nutrients consistent.

Can I grow it outdoors in a colder climate?

Absolutely. It handles cooler temperatures well and is often recommended for regions with short summers. Plant in spring or early summer for best results.

Does it need training?

LST (low-stress training) helps open up the canopy, but avoid topping or FIM—autoflowers don’t recover well from aggressive pruning.

How much smell does it produce?

Medium to high. The earthy, pungent aroma becomes strong in late flowering. Use a carbon filter if discretion is needed.

Can I use it for SCROG or SOG?

Yes for SOG (Sea of Green). SCROG is possible but less effective due to its bushy, wide structure. Stick to 9–16 plants per m² for SOG.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown dozens of autos, but White Widow Automatic stands out. I use it in my small balcony setup—just a 60x60x160 cm tent with a 250W LED. I planted three seeds in 20L pots with a soil-coco mix and added Worm Humus Biobizz at transplant. No topping, no fancy tricks—just consistent watering and a simple feed schedule. At day 80, I flushed with Canna Flush and harvested 52 grams of dense, trichome-covered buds. The high is smooth—relaxing but not couch-lock—and the flavor is true to the original. It’s my go-to when I want quality without complexity.
