Key specifications

History and origin

White Widow was created in the early 1990s in the Netherlands — a cross between a Brazilian sativa and a South Asian indica. The name comes from the buds densely coated in white trichomes — a resin production with few rivals. In 1995 White Widow won the Cannabis Cup and became the benchmark for the entire industry. More than 30 years later, it's still one of the most sought-after strains worldwide. For the full story and all variants, see our White Widow guide.

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.

White Widow THC level

The THC level of White Widow is 20–22% — remarkably high and consistent for a classic 50/50 hybrid. This stability is the result of decades of selection: no phenotype roulette, predictable potency in every grow. Beginners should start carefully with low doses.

White Widow effects: how does it feel?

The White Widow effect is two-phase and typical of a balanced hybrid:

• Euphoric, clear onset — the mind wakes up, a sociable and creative mood
• Physical relaxation — without heavy couch-lock at moderate doses
• Stress relief — ideal for the end of the day, reduces tension
• Creativity and focus — many users report heightened creativity
• Sedating effect — at higher doses, supports sleep

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.

Aroma and terpene profile

The aroma profile of White Widow has been a signature since the 1990s: earthy-spicy, woody, with a resinous sweetness and a slightly fresh finish. Especially attractive for extraction thanks to its exceptional resin production.

Growing — indoor and outdoor

Indoor growing

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.

Outdoor growing

Harvest in late September in the northern hemisphere — ideal for temperate climates. 0.5–1.5 kg per plant. Tolerant of moderate humidity swings; good airflow brings dense, frosty buds.
