White Widow Strain Regular SeedsThe 1990s Dutch classic as regular seeds, for breeders and mothers
5.00 out of 5 · 2 reviewsThe White Widow strain is the frost-covered Dutch hybrid that became an Amsterdam coffeeshop fixture after winning a Cannabis Cup in 1995, built from a Brazilian sativa and a South Indian indica. This page sells it as regular seeds, so expect roughly half the seedlings to turn out male. Breeders count on exactly that to make their own Widow crosses, and phenotype hunters use a full pack to find a keeper mother or simply grow the classic the old-school way.

What is the White Widow strain?
White Widow is an indica-leaning hybrid (about 60% indica, 40% sativa) created in the Netherlands in the early 1990s from a Brazilian sativa landrace and a South Indian indica. Most accounts credit Shantibaba (Scott Blakey), who bred it while at Green House Seeds, and it took first place at the 1995 High Times Cannabis Cup. Its name comes from the thick white layer of resin on the buds. As regular seeds, White Widow gives a mix of male and female plants; the females flower in about 8 to 10 weeks on 12/12 and test around 18–25% THC.
Green House Seeds lists 60% indica. AllBud flips it to 60% sativa, and individual plants range between both types.
White Widow's buds are so heavily frosted with trichomes that they look dusted in white, which gave the strain its name.
White Widow strain specs
The White Widow figures below come from Green House Seeds' current listing, SeedFinder, AllBud and Dutch Passion. Breeders publish one set of numbers for the strain rather than separate ones for regular seeds, and SeedFinder notes both tall, stretchy and short, compact phenotypes, so read every row as a range.

Where does the White Widow strain come from?
White Widow comes from a cross between a Brazilian sativa landrace and a resin-heavy South Indian indica from the mountains of Kerala, made in the Netherlands in the early 1990s. Most histories, including Sensi Seeds' and Wikipedia's, credit Shantibaba (Scott Blakey), who did the breeding while working at Green House Seeds in Amsterdam. Green House released it around 1994, and a year later White Widow won at the High Times Cannabis Cup.
The origin story has a second claimant. Dutch Passion says its White Widow line came straight from Ingemar, a Dutch breeder who maintains he made the original, and when Shantibaba moved his genetics to Mr. Nice Seeds he renamed his own version Black Widow. Because several lines exist, accounts even disagree on which landrace was the mother, so this page names both parents without assigning sexes.
Why buy White Widow as regular seeds?
Regular White Widow seeds give you males as well as females, which is exactly what breeders need. White Widow is one of the most used parents in cannabis: White Russian (× AK-47), White Rhino (× an Afghan indica), Blue Widow (× Blueberry) and Moby Dick (× Haze) all descend from it. A regular pack lets you select a strong male and make crosses of your own, something feminized seeds cannot do cleanly.
Regulars are also a way to find a keeper. Growing out a full regular pack shows the spread of White Widow phenotypes, from stretchy sativa-type plants to short, compact indica-type ones, so you can clone the best female and keep her as a mother.
What are White Widow's flavor and effects?
Aroma and flavor
White Widow tastes earthy and woody with a peppery spice, a pine edge and a light sweetness, and a few phenotypes add a sharp metallic or fuel note.
- Earthy
- Woody
- Pepper
- Pine
- Sweet
- Citrus
Terpenes
- Myrcene
- Musky, earthy base; Green House lists it first
- Alpha-pinene
- Sharp pine and resin
- Beta-caryophyllene
- Black-pepper spice on the exhale
Green House Seeds names these three as White Widow's most expressed terpenes; the balance can shift from plant to plant in a regular pack.
Reported effects
People most often describe White Widow as euphoric, happy and creative, with a brief relaxed body feeling at the start before a lively head high takes over. Green House calls the effect fast-acting and long-lasting.
- Euphoric
- Happy
- Creative
- Uplifted
- Energetic
White Widow's commonly reported downsides are dry mouth and dry eyes, a harsh, cough-inducing smoke, and a high that can feel too intense for people new to strong THC.
These White Widow reports are drawn from AllBud reviews and Green House Seeds' own description. Each body responds in its own way; nothing here is medical advice.
How do you grow White Widow seeds?
White Widow regular seeds grow easily indoors or out, but you need to sex them: germinate a few more seeds than the females you want, veg until pre-flowers appear, remove the males (or isolate one for breeding), then give the remaining females 8 to 10 weeks of bloom.
- Germinate3–7 days
Sprout more White Widow seeds than the number of plants you want to harvest. With regulars, plan on roughly half becoming males.
- Vegetate4–6 weeks
Grow White Widow until pre-flowers show at the nodes. Small round sacs on stalks mean male; a pointed calyx with wispy white hairs means female.
- Flower8–10 weeks
Pull or isolate every male before its pollen sacs open, then flip the females to 12/12. Expect a moderate stretch in the first 2 to 3 weeks.
- HarvestLate Sep–early Oct outdoors
Cut White Widow when most trichomes look cloudy with a few amber heads; the thick resin layer makes them easy to read with a loupe.
Grow tips for White Widow
- Sex early and carefully. Check White Widow pre-flowers with a loupe every few days. One missed male can seed a whole room of females.
- Keep a male only if you mean to breed. Move a chosen White Widow male to a separate room or tent and collect its pollen in a clean jar; left in the grow, it will pollinate everything nearby.
- Clone every female before flowering. Take a cutting from each White Widow female while she is still in veg. Once you have tested the buds, keep the winner as a mother plant.
- Use a carbon filter. Dutch Passion warns that White Widow gets pungent late in bloom and while drying, so control the smell indoors.
- Keep air moving through dense colas. Green House describes the buds as dense and frosty. Keep late-flower humidity low so moisture does not sit inside them.
- Outdoors, finish before the rain. White Widow ripens from late September to early October, so it suits mild climates with a dry start to autumn.
Is White Widow the right strain for you?
Great pick if you
- Want to breed your own crosses from a proven parent
- Want to hunt through phenotypes and keep a mother plant
- Like an upbeat, euphoric hybrid with an earthy, peppery taste
- Grow indoors or in a mild climate with 8 to 10 weeks to spare
Think twice if you
- Need a harvest from every single seed (the feminized version fits better)
- Have no time to check young plants for males
- Can't control strong smells late in flowering
- Need a sleepy, heavy nighttime indica
White Widow strain FAQ
Is White Widow indica or sativa?
White Widow is a hybrid. Green House Seeds lists it as about 60% indica and 40% sativa, AllBud reverses that, and plants range from tall sativa types to short indica types. Its effect leans lively and euphoric rather than sedating.
What does regular mean for White Widow seeds?
Regular White Widow seeds are not feminized, so each seed can become a male or a female plant, at roughly a 50/50 split. Only females produce the resinous buds. Males are removed before they shed pollen or kept apart for breeding.
How do I tell male from female White Widow plants?
Look at the nodes where side branches meet the main stem after about 4 to 6 weeks of growth. A male shows tiny ball-shaped pollen sacs hanging on short stems; a female shows a pointed calyx with thin white hairs. Remove males as soon as you are sure.
Who created White Widow?
Most sources credit Shantibaba (Scott Blakey), who bred White Widow at Green House Seeds in Amsterdam in the early 1990s. Dutch Passion credits a Dutch breeder named Ingemar, and Shantibaba later sold his own line as Black Widow through Mr. Nice Seeds.
How much THC does White Widow have?
Reported White Widow THC runs from about 18% to 25%. Green House Seeds has published test results of 18.76% and, more recently, 25.76%, while Dutch Passion puts most harvests near 20%. CBD stays low.
How long does White Widow take to flower?
Expect 8 to 10 weeks of bloom for White Widow after the lights go to 12/12, with Green House quoting 8 to 9 weeks. Outdoors in the Northern Hemisphere it finishes between late September and early October.
Why is it called White Widow?
The name comes from the strain's thick layer of trichomes, which makes the buds look white. That much frost was unusual when White Widow appeared in the 1990s and helped make it famous in Amsterdam.
What strains come from White Widow?
White Widow is a parent of many well-known strains, including White Russian (with AK-47), White Rhino (with an Afghan indica), Blue Widow (with Blueberry) and Moby Dick (with Haze). That track record is why breeders look for its regular seeds.
How much does White Widow yield?
Published White Widow yields run about 400–600 g/m² indoors, with Green House claiming up to 800 g/m², and up to 900 g per plant outdoors. In a regular pack, only the female plants count toward the harvest.

I damn love this strain! I love its potency that hits hard. I love the sweet fruity flavor. And I super love how easy it is to grow! This gurl doesn’t even need much participation and can thrive on its own. Talk about “strong and independent”. Highly recommend this for beginners and seasoned growers. Thanks!
