This autoflowering powerhouse packs the iconic, fast-hitting high and resin-drenched buds of the original White Widow into a compact, easy-to-manage plant that finishes in just over two months.

Ever feel like growing top-shelf weed is a full-time job, demanding strict light schedules and months of patience? You're not alone. That constant clock-watching and space management can suck the joy right out of the hobby, leaving you with stress instead of satisfaction. It's frustrating when you just want a reliable, potent harvest without turning your life into a grow-op documentary.

Enter the White Widow Auto. Green House Seeds expertly crossed their award-winning White Widow with robust Ruderalis genetics, creating a strain that flowers automatically based on age, not light cycles. This means no more light timers, no more worrying about light leaks, and a guaranteed harvest in about 9 weeks total. It's the perfect solution for busy enthusiasts, beginners, or anyone with limited space who refuses to compromise on quality.

Unlock Legendary Quality on Autopilot

This strain takes the guesswork out of growing while delivering the goods. Imagine harvesting dense, frosty nugs coated in a blanket of trichomes that sparkle like sugar. The effect is a classic, well-balanced hybrid high: it starts with a relaxing, full-body stone that melts away tension, then smoothly transitions into a clear, cerebral buzz that's perfect for creative sessions or socializing. It's a fast-hitter with long-lasting power, exactly what made the original a global phenomenon.

How to Grow Your White Widow Auto for Maximum Results

Growing this champion is straightforward, making it ideal for your first autoflower or a reliable staple in the garden. Follow these steps for a stress-free journey from seed to stash.

1. Start Smart: Germinate your seeds in a warm (22–25°C / 71–77°F), humid environment. For a strong, healthy start that reduces transplant shock, consider using a root stimulator from day one.
2. Pot and Substrate: Autoflowers dislike being transplanted. Plant directly into their final pot, ideally 11–20 L (2.9–5.3 gal). Use a light, airy, and well-draining soil mix or coco coir to encourage rapid root development.
3. Light and Environment: Provide 18-20 hours of light daily throughout its entire life. Maintain temperatures between 20-26°C (68-79°F) and lower humidity gradually from 60% in seedling stage to 40-50% during flowering to prevent mold.
4. Low-Stress Training (LST): Gently bend and tie down branches during the first 3-4 weeks. This technique opens up the canopy to light, encouraging multiple colas and significantly boosting your final yield without stressing the plant.
5. Feeding Strategy: Start with a mild nutrient solution and increase strength gradually. Autoflowers have a shorter life cycle, so they are more sensitive to overfeeding. During the flowering stretch, a balanced autoflowering nutrient formula will support bud development without causing nutrient burn.
6. The Final Weeks: In the last two weeks, flush the plant with plain, pH-balanced water. This clears any residual nutrients from the soil, leading to a smoother, cleaner smoke. Harvest when the trichomes are mostly milky with some amber for a balanced effect.

Key Advantages and Benefits of White Widow Auto

• Automatic Flowering: Because it flowers based on age, you get a guaranteed harvest in approximately 63 days from seed, eliminating the need for strict 12/12 light schedules and simplifying your grow.

Care and Post-Harvest Tips

This plant is low-maintenance but thrives with attention to airflow and humidity. Ensure good ventilation in the final weeks to protect the dense, resinous buds from botrytis. After harvest, dry slowly in a dark space with 50-60% RH and 18-20°C (64-68°F) for 7-10 days. For the signature smooth White Widow smoke, cure the dried buds in airtight jars for a minimum of 2-4 weeks, burping them daily for the first week. This process enhances the complex spicy-sweet flavors and smooths out the smoke.

Frequently Asked Questions

Is White Widow Auto suitable for first-time growers?

Absolutely. Its autoflowering nature, compact size, and forgiving temperament make it one of the best choices for beginners. You don't need to manage light schedules, and it's resilient against common beginner mistakes like slight overwatering or minor nutrient imbalances.

How does the autoflowering version compare to the original photoperiod White Widow?

The auto version captures the essential character, potency, and flavor of the original but in a shorter, more compact plant. The main trade-off is a slightly reduced maximum yield potential and less time for vegetative training. However, for speed, discretion, and simplicity, the Auto is often the preferred choice.

Can I grow White Widow Auto outdoors in a colder climate?

Yes, but with timing and protection. Its fast 9-week cycle allows you to harvest before the first frosts in many regions. For best results, start it indoors for 2-3 weeks to get a strong seedling, then move it outside after the last frost. Using a small greenhouse or cloche can extend your growing window in cooler areas.

What's the best way to increase yield with this autoflower?

Focus on low-stress training (LST) and optimal environment. Avoid topping or other high-stress techniques. Use LST to open the canopy during the first month. Also, ensure it's in its final pot from the start and provide consistent, high-intensity light (18-20 hours daily) throughout its life. A quality bloom booster during weeks 3-6 of flowering can also help maximize bud density and resin production.

Personal Experience of Pevgrow’s CEO (Alan)

I've run White Widow Auto in my personal garden more times than I can count—it's a classic for a reason. For me, it's the ultimate "set and forget" strain when I want guaranteed quality without babysitting. I always plant directly into a 15 L (4 gal) fabric pot with a light soil mix and let it do its thing under 18/6 light. The key is resisting the urge to overfeed; these autos are light eaters. I get the best results when I use LST early to bush it out, which turns this naturally compact plant into a multi-cola beast. The smell during late flower is a delicious, spicy-sweet aroma that definitely benefits from a carbon filter indoors. The smoke? Exactly what you'd hope for: that iconic, powerful White Widow punch that starts in the body and lifts your mind, perfect for unwinding after a long day. It's a staple in my rotation for its reliability and timeless effect.
