What is the White Widow strain?
White Widow is a Dutch hybrid of a Brazilian sativa and a South Indian indica, introduced by Green House Seeds in Amsterdam around 1994 and famous for buds that turn white with resin. Green House rates it about 60% indica. The feminized seeds sold here grow only female plants, which bloom for roughly 8 to 9 weeks once the light is cut to 12 hours a day. Published THC runs from about 18% to 25%, with myrcene, pinene and caryophyllene as the lead terpenes.

The trichome layer is so visible that it gave White Widow its name and made it stand out in 1990s Amsterdam.

Where does the White Widow strain come from?
White Widow was bred in Holland in the early 1990s by crossing two landraces: a sativa from Brazil and an indica from the Kerala region of South India. Shantibaba (Scott Blakey), then working with Arjan Roskam's Green House Seeds, is usually named as the breeder. Green House released the strain around 1994, and it placed first at the High Times Cannabis Cup in 1995.
Today Green House sells White Widow as feminized seed, and many other seed makers offer feminized lines of it too. Those lines are not all identical: Dutch Passion's White Widow traces to a breeder named Ingemar, and the version Shantibaba took to Mr. Nice Seeds was renamed Black Widow. That explains why THC, flowering and yield figures differ between listings.
What is the difference between feminized and regular White Widow?
Feminized White Widow seeds grow female plants only, while regular seeds give a mix of roughly half males and half females. With feminized seeds, every plant you raise can produce buds, so there is no need to inspect pre-flowers or pull males. Regular seeds suit breeders; feminized seeds suit growers who want a harvest from every plant they start.
Feminized seeds work well for Sea of Green. Because every White Widow plant is female, you can fill a tent with many small plants and put them into flower early, a method Green House recommends for this strain.

- Creative
- Euphoric
- Uplifting
Users of White Widow mention dry mouth, coughing from the expanding smoke and, for newer smokers, a high that can feel too strong.

How do you grow White Widow seeds?
Feminized White Widow is one of the easier classics to grow: veg it for a few weeks, move it to a 12/12 light cycle, and harvest after 8 to 9 weeks of flowering. Its short, bushy indica frame fits small tents, and every seed grows a female plant.
- Germinate2–5 days
Soak the seeds or use a damp paper towel; sprouted White Widow seeds go straight into small pots or plugs.
- Vegetate2–6 weeks
For Sea of Green, start flowering small White Widow plants after 2 to 3 weeks; for SCROG, veg longer and fill the screen first.
- Flower8–9 weeks
White Widow stretches moderately in early bloom, then packs on tight, frosty buds from about week 4 onward.
- HarvestDay 56–63 · late Sept outdoors
Harvest when the trichomes turn mostly milky; wait for more amber if you want a heavier, calmer finish.
Grow tips for White Widow
- Run a Sea of Green. Every feminized White Widow plant is female, so a tent full of small, single-cola plants is efficient. Green House lists SOG as a good fit.
- Keep the dark period truly dark. Light leaks during the 12-hour night can stress feminized plants into growing male flowers. Seal the tent and check for gaps.
- Thin out the lower growth. Short internodes and big leaves make White Widow bushy. Clear the bottom third so energy and air go to the top buds.
- Plan for the smell. Dutch Passion warns that White Widow's scent gets strong late in flowering and while drying, so fit a carbon filter early.
- Protect the trichomes. Handle the buds gently at harvest and dry them slowly in a cool, dark room; most of White Widow's appeal is its resin coat.
- Outdoors, give it a mild climate. In temperate gardens White Widow can reach about 170 cm and finish by the end of September, ahead of most autumn rain.

White Widow strain FAQ
Do White Widow feminized seeds grow only female plants?
Yes. Feminized White Widow seeds are bred to produce female plants, the ones that grow buds. Stress such as light leaks or big temperature swings can occasionally push a plant to grow a few male flowers, so keep conditions stable.
Is White Widow a sativa or an indica?
White Widow is a hybrid. Green House Seeds rates it around 60% indica and SeedFinder calls it mostly indica, but the strain is better known for energy and euphoria than for sedation.
How long does feminized White Widow take to flower?
Feminized White Widow flowers in about 8 to 9 weeks (56–63 days) after you change the lights to 12/12. Dutch Passion says its feminized line averages about 8 weeks indoors.
How much does White Widow yield indoors?
Databases such as SeedFinder report 400–600 g/m² indoors, and Green House Seeds claims up to 800 g/m² in a well-run Sea of Green or SCROG. Outdoors, Green House cites up to 900 g per plant.
How tall does White Widow grow?
White Widow stays compact indoors, usually around 75–100 cm according to Dutch Passion, with short internodes and a bushy shape. Outdoor plants reach about 170 cm.
What is the THC level of White Widow?
White Widow commonly tests between about 18% and 25% THC. Green House's most recent published result is 25.76% THC with 0.10% CBD, but most harvests land lower than that.
Is Black Widow the same as White Widow?
Black Widow is the name Shantibaba gave his original White Widow line after leaving Green House Seeds for Mr. Nice Seeds. It shares the same roots, but Black Widow products from different seed makers may not match it.
What does White Widow smell like?
White Widow smells earthy and spicy with woody and pine notes and a sweet edge. Some plants carry a metallic or diesel-like twist, and the scent gets strong in the last weeks of flowering.
Did White Widow win a Cannabis Cup?
Yes. Green House Seeds lists a first place at the 1995 High Times Cannabis Cup for White Widow, the win that made it a fixture in Amsterdam coffeeshops.
