White Widow is a balanced indica–sativa hybrid created in the Netherlands in the mid-1990s from a Brazilian sativa and a South Asian indica. The name comes from the buds, which are so densely coated in white trichomes that they look frosted — a resin production with few rivals. In 1995 White Widow won the Cannabis Cup and became the benchmark for a whole generation of hybrids. More than 30 years later, the White Widow strain is still one of the most sought-after classics worldwide and a parent of many modern crosses.
Pyramid Seeds cultivates this line with a focus on even internodal spacing, a predictable terpene profile and a stable THC window of 20–22% — the reference White Widow for consistent results. For the full story of the strain and all eight variants, read our White Widow strain guide.
The THC level of White Widow is 20–22% — high and consistent for a classic 50/50 hybrid, with CBD below 1%. This stability is the result of decades of selection: no phenotype roulette, predictable potency in every grow. Beginners should start carefully with low doses. Looking for a gentler version? White Widow CBD keeps the character with a CBD-rich profile.
The White Widow effect is two-phase and typical of a balanced hybrid:
How does White Widow feel compared to pure indicas or sativas? As a 50/50 hybrid it delivers the best of both worlds — without the extreme sedation of an indica or the over-activation of a sativa. That makes it the most versatile strain in the classic canon.
The aroma profile of White Widow has been a signature since the 1990s: earthy-spicy, woody, with a resinous, candy-like sweetness and a slightly fresh finish. Especially attractive for extraction thanks to its exceptional resin production.
| Terpene | Typical impressions | Contribution to the profile |
|---|---|---|
| Myrcene | Earthy, musky, sweet | The base of the relaxing body effect — the classic indica terpene |
| Caryophyllene | Spicy, peppery, warm | The characteristic spice, anti-inflammatory properties |
| Pinene | Fresh, pine-like, clear | A fresh finish, supports mental clarity and focus |
White Widow is rated easy: compact, uniform plants, a short flowering time and a forgiving nature make it a classic first strain — and a reliable performer for experienced growers. Start with our step-by-step guide on how to germinate cannabis seeds; because the seeds are feminized, you do not need to sort out male plants.
Switch to 12/12 when the plants have reached about half of the final height you want. Flowering time 60 days (LED: 53 days). Yield: 500 g/m² standard, up to 800–850 g/1.5 m² with a 720 W LED. Very well suited to SCROG and LST — compact growth with plenty of side shoots. Keep humidity below 50% in late flowering — dense buds are prone to botrytis.
Outdoors, White Widow finishes in the second to fourth week of September in the northern hemisphere (March in the southern hemisphere) and yields 0.5–1.5 kg per plant. That timing suits short seasons — the UK, northern and central Europe, Canada and the northern US — where a sunny, sheltered spot or a greenhouse helps the buds ripen before the autumn rain. In long seasons — southern Europe, California and the southern US — plants grow larger and reach the top of the yield range. Tolerant of moderate humidity swings; good airflow brings dense, frosty buds.

White Widow is a classic Dutch hybrid from the mid-1990s, bred from a Brazilian sativa and a South Asian indica. It won the Cannabis Cup in 1995 and is famous for buds so covered in white trichomes that they look frosted.
White Widow is a balanced 50/50 hybrid — neither clearly indica nor sativa. The effect reflects that: an initial sativa-leaning euphoria and creativity, followed by indica-leaning body relaxation.
The White Widow THC level at Pyramid Seeds is 20–22%, with CBD below 1%. That places it among the stronger classic strains with a balanced hybrid profile.
The White Widow effect is two-phase: a euphoric, clear head effect followed by a pleasant physical relaxation. At moderate doses it stays functional and creatively stimulating; at high doses it becomes sedating. Ideal for the end of the day and stress relief.
60 days indoors — as little as 53 days under LED. Outdoors in the northern hemisphere, White Widow is ready in the second to fourth week of September; in the southern hemisphere, in March.
Yes. White Widow is rated easy: compact, uniform growth, a short flowering time and a forgiving nature. The main thing to watch is humidity in late flowering, as the dense buds can develop mould if the air is too damp.
The name refers to the buds densely coated in white trichomes — a resin production that has made this strain famous since the 1990s. The "white widow" is named for the look of its crystal-covered flowers.
No. “Feminized” is the American spelling and “feminised” the British one — both mean the same seeds, which grow into practically only female plants.
Yes — Auto White Widow flowers with no light schedule in 65 days from germination and is ideal for fast harvests without light management. There are also CBD versions: White Widow CBD and Auto White Widow CBD.
