Auto White Widow Cannabis Seeds by Dutch Passion
Auto White Widow is a feminized autoflowering cannabis seed that delivers the legendary White Widow genetics in a compact, fast-finishing plant ready to harvest in just 70-75 days from germination. Dutch Passion spent several years of selective breeding crossing their original award-winning White Widow mother plant into a ruderalis-infused autoflower — and the result genuinely lives up to the name. Dense, resin-caked buds with that unmistakable fresh pine and citrus profile, all from a plant that rarely tops 100cm.
Pack Sizes
| Pack | Seeds | SKU |

Go for the 3-pack if you want to run a single cycle and see how she performs in your setup. The 7-pack gives you room for multiple runs or a sea-of-green approach where you can fill a tent with uniform plants.
Why Auto White Widow Seeds Deserve a Spot in Your Grow
The original White Widow has been a coffeeshop staple since the mid-'90s — we've watched it dominate Cannabis Cup podiums and seed bank bestseller lists for over two decades. The problem was always timing. Photoperiod White Widow needs a careful 12/12 light flip, a separate veg space, and 8-9 weeks of flowering on top of however long you vegetate. Dutch Passion's Auto White Widow strips all that away.
You germinate, you wait 70-75 days, you harvest. No light schedule changes, no sexing (they're feminized), no clock-watching beyond keeping your nutrient schedule on point. The plants stay between 60-100cm — short enough for a 120cm tent with a light and carbon filter above the canopy, bushy enough to produce serious weight. Indoors, experienced growers pull 200g+ from a single plant. Outdoors in a decent European summer, expect 50-150g per plant depending on your latitude and how much direct sun the girls get.
The one honest limitation: autoflowers don't let you extend veg time to recover from early mistakes. If you overwater or burn the seedlings in week one, you can't just give them an extra fortnight of veg to bounce back. The clock is ticking from day one. So get your medium, pH, and feeding dialled in before you pop these seeds. That said, Auto White Widow is genuinely forgiving once established — vigorous growth, strong branching, and she adapts to soil, coco, or hydro without complaint.
Growing Auto White Widow — What to Expect
Auto White Widow adapts to any cultivation method, but Dutch Passion specifically notes that the best results come from a deep water culture (DWC) hydro setup. The root access and oxygen availability in DWC push these plants to their upper yield potential. In soil or coco, you'll still get excellent results — just keep the pot size reasonable (11-15L) and don't transplant. Start in the final container to avoid root shock slowing down an already time-limited lifecycle.
During flowering, the aroma gets loud. Fresh, sweet, citrusy with that distinctive pine backbone. If you're growing indoors, your carbon filter needs to be in good shape — not "it'll probably be fine" shape, but actually checked and replaced if it's been running more than 12-18 months. The resin production is heavy and the terpene output matches. Your tent will smell like a Dutch coffeeshop by week five.
The buds develop dense and hard, elongated in structure with a thick coating of trichomes that makes them look frosted. Pistils come through white, very light green, and orange — visually striking even before you trim. The plant's bushy Indica-dominant structure means most of the bud sites get decent light penetration without heavy training, though a bit of gentle LST in the first three weeks won't hurt.

Flavour, Aroma, and the Auto White Widow Effect
The smoke delivers a fresh, fairly sweet and citrusy taste with a clear touch of pine on the exhale. It's recognisably White Widow — if you've ever had the original in an Amsterdam coffeeshop, you'll clock the genetics immediately. The terpene profile leans toward limonene and pinene territory, which tracks with that bright, resinous nose.
The effect is a hard-hitting, almost instant onset. Dutch Passion describes it as a well-balanced, powerful combination — a pleasantly relaxing physical sensation paired with an intense cerebral component. According to a study examining user-reported strain preferences (Pearce et al., 2014, PMC4869908), White Widow was specifically noted by participants as a strain associated with reported pain management properties. Additionally, research published in PMC6275121 (Cahill et al., 2018) documented user reports describing White Widow as "a great painkiller" in the context of self-reported therapeutic use.
According to an in vitro and in vivo study using Cannabis sativa White Widow hybrid material (PMC11207413, 2024), researchers investigated anti-inflammatory properties of the cultivar, though results should be understood within the context of controlled laboratory conditions rather than as direct consumer health claims.
Auto White Widow Compared to Photoperiod White Widow
The obvious comparison is Dutch Passion's own photoperiod White Widow Feminized. Here's the honest breakdown:
| Feature | Auto White Widow | Photoperiod White Widow |
|---|---|---|
| Total time (seed to harvest) | 70-75 days | 12-16 weeks (veg + 8-9 weeks flower) |
| Height | 60-100cm | 100-180cm |
| Light schedule | 18/6 or 20/4 throughout | 18/6 veg, 12/12 flower |
| Max indoor yield | 200g+ per plant | 400g+ per plant |
| Training flexibility | Limited (LST only, no topping recommended) | Full (top, FIM, SCROG, mainline) |
| Difficulty | Easy | Moderate |
If you've got a tall tent, experience with training techniques, and patience, the photoperiod version will out-yield the auto every time. But if you want two or even three harvests per outdoor season, or you're running a small indoor space where 100cm plants are the maximum, Auto White Widow is the smarter pick. We'd grab the auto for balcony grows and stealth setups — the photoperiod for dedicated indoor rooms where you can let plants fill a SCROG net.
Complete your setup with a carbon filter and extraction fan — Auto White Widow's flowering aroma is intense and your neighbours will appreciate the discretion. If you're running DWC for maximum yield, pair these seeds with an air pump and net pots sized for the system.
How to Grow Auto White Widow Seeds
- Germinate seeds using the paper towel method or directly in a pre-moistened jiffy pellet. Maintain 22-25°C and expect taproots within 24-72 hours.
- Plant the germinated seed (taproot down) 1cm deep in your final container — 11-15L pot for soil/coco, or directly into your DWC net pot with clay pebbles. Do not transplant autoflowers.
- Set your light schedule to 18/6 or 20/4 from day one and keep it there for the entire lifecycle. No light change needed.
- Begin light feeding around day 10-14 with a seedling-strength nutrient solution. Auto White Widow is vigorous but still sensitive in the first two weeks — half-strength is plenty.
- If using LST, begin gentle tie-downs around day 14-21 while stems are still flexible. Avoid topping — the plant doesn't have time to recover fully.
- Transition to bloom nutrients when you see the first pistils (usually around day 25-30). The plant handles the switch on its own — you just change the feed.
- Monitor trichome colour from day 60 onwards. Harvest when trichomes shift from clear to mostly milky with a few amber — typically around day 70-75.
- Dry in a dark, ventilated space at 18-20°C and 55-60% humidity for 7-10 days, then cure in glass jars for at least two weeks.
Frequently Asked Questions
How long does Auto White Widow take from seed to harvest?
70-75 days total from germination to harvest-ready buds. No light schedule change required — the plant flowers automatically based on age, not photoperiod.
Is Auto White Widow easy to grow for beginners?
Yes. Dutch Passion rates it as easy. The main thing to get right is your starting medium and container — plant directly in the final pot, don't overwater seedlings, and let the autoflower genetics do the rest. She's vigorous and forgiving once past the first two weeks.
What yield can I expect from Auto White Widow indoors?
Up to 200g+ per plant in experienced hands, particularly in a DWC hydro setup. In soil or coco with standard nutrients, 100-150g per plant is more realistic for intermediate growers. Outdoors, expect 50-150g per plant depending on sun exposure.
Does Auto White Widow smell a lot during flowering?
Yes — strongly. The fresh citrus and pine terpene profile gets loud from mid-flower onwards. A functioning carbon filter is not optional for indoor grows. Check your filter's condition before starting a run with these seeds.
What's the best growing medium for Auto White Widow?
Dutch Passion specifically recommends deep water culture (DWC) hydroponics for maximum results. Soil and coco coir both work well too — just use a light, airy mix and avoid heavy clay-based soils that restrict root growth in the limited timeframe.
Can I top or train Auto White Widow plants?
Gentle low-stress training (LST) in the first three weeks works well. Avoid topping or high-stress techniques — the plant doesn't have enough vegetative time to recover fully, and you'll likely lose yield rather than gain it.
How tall does Auto White Widow get?
Between 60-100cm in most conditions. Indica-dominant structure keeps her bushy and compact. She'll fit comfortably in a 120cm tent with room for your light and filter above the canopy.
