Auto White Widow by Dutch Passion – Fast Autoflowering Strain with High THC & Frosty Buds

Auto White Widow by Dutch Passion is a fast, high-THC autoflowering strain that delivers dense, frosty buds in just 10–12 weeks, perfect for growers seeking quality with minimal effort.

Still dreaming of big, stoned buds but stuck with limited time or space? Regular photoperiod strains demand strict light cycles and months of patience. Miss one darkness period and you’re set back weeks. And if you're growing outdoors in a short summer, most varieties won’t even finish before the cold hits.

That stress, that fear of failure, the wasted electricity and nutrients — it kills the joy of growing. You want results, not guesswork. You want a strain that works as hard as you do, without the drama.

Meet Auto White Widow: the no-stress powerhouse that finishes fast and hits hard. With genetics rooted in the legendary White Widow, this autoflower delivers rock-hard, trichome-blanketed buds in record time. No light cycle changes needed — just plant, feed, and watch it thrive under 18–20 hours of daily light. From germination to harvest in 70–90 days, you’ll get up to 200 g (7.05 oz) per plant indoors and consistent outdoor yields even in cooler climates. It’s the ultimate set-and-forget strain for reliable, high-potency harvests.

Before Growing Auto White Widow

Before you start with Auto White Widow, make sure you’ve got a stable environment — this strain thrives when temperature and humidity are kept consistent. Since it’s an autoflower, you won’t need to switch light schedules, but you will need to plan your pot size early. Choose a final pot between 18–27 L (0.64–0.95 ft³) to avoid transplant stress. If you're growing in soil, consider using a light, well-aerated mix like Root Juice BioBizz to boost early root development.

• Germinate seeds in a warm, dark, moist environment (22–25 °C)
• Use 18–27 L (0.64–0.95 ft³) pots from the start for autos
• Choose airy substrates like coco or light soil mixes
• Set up carbon filters early — this strain smells strong
• Begin with 18–20 hours of light per day

During the Grow: Vigour, Structure & Care

Auto White Widow grows fast, with a compact, bushy structure that’s perfect for small spaces or stealth grows. It shows vigorous growth in the first 3–4 weeks, then transitions smoothly into flowering around day 25–30. Unlike photoperiods, you can’t top or heavily prune this strain — it follows its own internal clock. But you can gently train branches with low-stress techniques (LST) to expose more bud sites. Keep humidity at 50–60% during vegetative growth, then drop to 40–50% in flowering to prevent mold. For stronger development, consider adding Root Juice BioBizz in early veg to support root mass and resilience.

The plant typically reaches 0.60–1.10 m (1.97–3.61 ft), making it ideal for indoor tents or discreet outdoor setups. Indoors, you’ll see dense, resinous colas forming under strong lighting — especially in hydro systems like DWC. Outdoors, it’s ready by late summer, avoiding autumn rains in northern regions. Its thick layer of trichomes not only looks impressive but also protects against pests and UV stress.

After Harvest: Yield, Effects & Maintenance

After 10–12 weeks, you’ll harvest heavy, sticky buds with a THC content averaging 15–20%. Indoors, expect up to 450–500 g/m² (13.23–14.79 oz/ft²), while outdoor plants yield 50–150 g (1.76–5.29 oz) per plant depending on conditions. Once cured, the aroma intensifies — think sweet citrus, vanilla, and sharp skunk. The effect is balanced: a euphoric head rush followed by deep physical relaxation, perfect for evening use.

Maintenance is minimal: just clean your grow space thoroughly to avoid residue buildup. No special equipment needed — just trim, dry at 18–22 °C (64.4–71.6 °F) and 50–60% RH, then cure in jars for 2–4 weeks. The result? Smooth, flavorful smoke with a long-lasting stone.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown Auto White Widow three times now — once in DWC under LEDs, once in soil outdoors, and once in coco with a SCROG setup. Every time, it delivered. The first thing I noticed? That frosty white layer of trichomes — it’s real, and it’s spectacular. I used 20/4 lighting throughout and started with 20 L pots. No topping, just gentle LST to open up the canopy.

By week 5, the smell was intense — like citrus and diesel in a good way. I added Root Juice BioBizz in week 2 and saw stronger root development. In DWC, I got 149 g (5.26 oz) from one plant. Outdoors, I harvested 120 g (4.23 oz) under full sun. The high? Instant. Euphoric, then deeply relaxing — perfect after a long day. If you want a strain that’s easy, fast, and hits hard, this is it.
