White Widow Regular Cannabis Seeds by Royal Queen Seeds
White Widow regular is a photoperiod hybrid cannabis seed producing plants with a 50/50 chance of male or female expression — the classic genetic format that breeders and clone-takers actually want. Descended directly from the original White Widow S1, these regular seeds from Royal Queen Seeds carry the full genetic diversity of one of Amsterdam's most storied strains. If you've only ever grown feminized or autoflower seeds, regulars are where you learn what cannabis actually does when you let it do its thing.
Pack Sizes
White Widow regular comes in two pack sizes: 10 seeds and 25 seeds. With regular seeds, roughly half your plants will be male. A 10-pack gives you around 5 potential females — enough for a single indoor cycle. The 25-pack is the better shout if you're pheno-hunting or planning a breeding project, since you'll have a wider genetic pool to select from. We'd grab the 25 if you're serious about finding a keeper mother plant.
Why White Widow Regular Seeds Belong in Your Grow
Regular cannabis seeds are the unfiltered version of the plant. No chemical reversal, no genetic tweaking — just a natural cross that produces both male and female offspring. That's not a limitation; it's the whole point. Male plants carry half the genetics you need to create new crosses, stabilise traits, or simply find the strongest female phenotype in a batch. White Widow regular gives you that raw material from one of the most proven genetic lines in existence.
The original White Widow turned up in Dutch coffeeshops in the mid-1990s — a Brazilian sativa crossed with a South Indian indica resin machine. The result was a plant so caked in trichomes it looked like it had been dipped in icing sugar. That resin production isn't just for show. It's the reason White Widow became a breeding backbone for dozens of modern hybrids. Royal Queen Seeds' regular version preserves that lineage without the shortcuts of feminization, so you're working with the strain's full genetic expression.
One honest limitation: regular seeds mean you'll need to sex your plants. That adds a step to your grow — you'll be checking for pollen sacs around week 2–3 of flowering and removing males unless you're deliberately breeding. It's not difficult, but it does require attention. If you just want to grow bud with zero fuss, feminized White Widow seeds exist for that. These regulars are for growers who want more control, not less work.
Growing White Widow Regular Seeds — What to Expect
White Widow regular is a cooperative plant that doesn't punish small mistakes. Indoor heights stay between 60–100cm, which means she fits comfortably in a standard 120x120cm tent without aggressive training. Outdoors, expect 150–190cm — tall enough to produce serious colas but not so towering that she draws attention from three gardens over.

Training responds well here. Topping the main stem early in veg encourages a bushier canopy with more bud sites, and low-stress training (LST) lets you spread branches horizontally to maximise light exposure. If you're growing in a smaller space, these techniques aren't optional — they're how you keep a 50/50 hybrid from outgrowing your tent. Large containers or garden beds suit these plants best; don't try to squeeze them into 5-litre pots and expect full yields.
After 8–10 weeks of flowering under a 12/12 light cycle, female plants deliver up to 500g/m² indoors. Outdoors, with a full season of sun and enough root space, individual plants can push 550–600g each. Those are proper numbers for a regular seed — comparable to many feminized strains, which tells you something about the vigour in this genetic line.
Flavour, Aroma, and Terpene Profile of White Widow
Crack open a cured jar of White Widow and the first thing that hits you is earth — damp, dark, forest-floor earth. Then the pepper arrives, not gentle black pepper but that sharp, almost prickly spice that catches the back of your throat. Underneath it all sits a warm, woody undertone that rounds the whole thing out. It's not a fruity strain. It's not a dessert strain. White Widow smells like what cannabis smelled like before everything got crossed with Gelato.
Smoked or vaped, those earthy and peppery notes translate directly. The smoke is dense but smooth enough for a longer session. Through a dry herb vaporiser at around 185–195°C, you'll pull more of the spice and less of the combustion harshness — a good way to appreciate the terpene profile without the tar. The trichome coverage on properly grown White Widow buds is genuinely impressive; that frosty, almost white appearance isn't marketing, it's what the plant actually looks like when it's been given decent light and nutrients.
According to a 2023 study examining morphological traits of cannabis cultivars, trichome density and structure vary significantly across strains and directly influence resin production and aromatic compound concentration (PMC10610221). White Widow has been a reference point for high-trichome cultivars for nearly three decades — the name itself describes the visual result of that resin output.
White Widow Regular for Breeding and Cloning
This is where regular seeds earn their keep. Feminized seeds are convenient, but they're a dead end if you want to create something new. White Widow regular gives you access to both male and female plants, which means you can select the best male for pollen production and cross it with your strongest female — or with an entirely different strain.
A practical breeding approach: germinate the full pack, veg all plants for 3–4 weeks, then flip to 12/12. Males will show sex first, usually within the first 1–2 weeks of the flowering light cycle. Isolate the males you want to keep (look for vigorous growth, tight node spacing, and strong stems — these traits tend to pass to offspring). Collect pollen and apply it selectively to specific branches of your chosen female. The rest of her buds remain seedless and smokeable.
For cloning, regular females often root faster and show more genetic stability than feminized plants. Once you've identified a female phenotype you love — maybe one that leans more indica-dominant with extra resin, or a sativa-leaning pheno with taller structure and spicier terps — take cuttings and you've got a mother plant that can supply clones indefinitely. We've seen growers keep a White Widow mother going for years.
Effects and Research Context
White Widow's balanced 50/50 indica-sativa genetics produce a high that's been described by users as initially cerebral and uplifting, settling into a more relaxed physical state. The strain's THC content typically falls between 18–25%, depending on phenotype and growing conditions.
According to a 2024 in vitro and in vivo study examining anti-inflammatory and other properties of Cannabis sativa L. (White Widow hybrid), researchers observed measurable biological activity in both leaf and inflorescence extracts (PMC11207413). This is strain-specific research — not a generic cannabis study — which makes it particularly relevant to White Widow growers interested in the science behind what they're cultivating.
Common side effects reported across cannabis strains at this THC range include dry mouth, dry eyes, and at higher doses, dizziness or increased anxiety. Keeping a glass of water nearby and starting with a modest amount if you're unfamiliar with the strain is just common sense.
Complete your setup: pair White Widow regular seeds with a complete grow kit including tent, lighting, and ventilation. If you're planning a breeding project, a jeweller's loupe helps you inspect trichome development and sex your plants early. For drying and curing, mason jars with humidity packs keep those earthy, peppery terpenes intact.
How to Grow White Widow Regular Seeds
- Germination: Place seeds between damp paper towels on a plate, cover with a second plate, and keep at 20–25°C. Taproots typically emerge within 24–72 hours. Transfer to small pots of lightly moistened seedling soil once the taproot is 1–2cm long.
- Seedling stage (1–2 weeks): Keep under 18/6 lighting at low intensity. Don't overwater — the most common seedling killer is soggy soil. Let the top centimetre dry out between waterings.
- Vegetative growth (3–5 weeks): Increase light intensity gradually. This is your window for topping and LST. Top once above the 4th or 5th node to encourage lateral branching. Use soft plant ties to bend branches outward.
- Sexing (first 1–2 weeks of 12/12): Switch to a 12/12 light cycle to trigger flowering. Males show small round pollen sacs at the nodes; females show white pistils (hairs). Remove males promptly unless breeding — a single burst pollen sac can seed an entire room.
- Flowering (8–10 weeks): Maintain 12/12 lighting. Feed bloom nutrients according to your chosen nutrient line. Watch for the trichomes to shift from clear to milky — that's your harvest window. Some growers wait for 10–20% amber trichomes for a more relaxed effect.
- Harvest, dry, and cure: Cut branches and hang in a dark, ventilated space at 18–21°C and 55–65% humidity for 7–14 days. Trim and transfer to airtight jars, burping daily for the first 2 weeks. A proper 4-week cure brings out those deep earthy and spicy terpenes.
Frequently Asked Questions
What's the difference between White Widow regular and feminized seeds?
Regular seeds produce both male and female plants — roughly a 50/50 split. Feminized seeds are bred to produce only females. Choose regular if you want to breed, take clones from a selected mother, or explore different phenotypes. Choose feminized if you just want bud with no sexing involved.
How many female plants can I expect from a 10-pack of White Widow regular?
On average, about 5 out of 10 will be female. It's a coin flip per seed, so you might get 4 or 6 in practice. The 25-pack gives you better odds of finding multiple strong females for selection.
Can beginners grow White Widow regular seeds?
Yes. The plants are forgiving and adaptable to both indoor and outdoor environments. The only extra step compared to feminized seeds is identifying and removing males during early flowering — a skill that takes about 10 minutes to learn.
What does White Widow taste like when smoked?
Earth, pepper, and warm spice dominate. It's a savoury, old-school cannabis flavour — no fruit, no candy. Through a vaporiser at 185–195°C, the spice notes come through more clearly without combustion masking them.
How tall does White Widow regular grow indoors?
Indoor plants reach 60–100cm depending on pot size, training, and veg time. Topping and LST keep height manageable in smaller tents. Without training, expect the upper end of that range.
Is White Widow regular good for breeding projects?
It's one of the best choices for home breeding. The genetic line is stable and well-documented, males tend to be vigorous pollen producers, and the strain crosses well with both indica and sativa genetics. Many modern hybrids trace back to White Widow parentage.
What yield can I expect from White Widow regular indoors?
Female plants can produce up to 500g/m² indoors under optimised conditions — proper lighting, nutrients, and training. Outdoors, individual plants can reach 550–600g each with a full growing season.
