Type and Genetics

White Widow has been produced by White Label, the generic brand of Sensi Seeds, sourced from the original seeds of Black Widow by Mister Nice Seedbank. It's a hybrid with dominating performance and exceptional vigor.


The plants grow strong and well-branched, with an almost black dark green color. From the second half of the flowering phase, they acquire the white hue that gives them their name, due to the large amount of trichomes they produce.

Aroma and Flavor

With a strong smell of noble wood, an accompanying bittersweet and slightly spicy taste, this amazing strain impresses all.


White Widow has a strong effect, both physical and cerebral. Despite having been created many years ago, it still competes with today’s most potent strains.


This high-yielding strain never disappoints commercial growers, as it can yield up to 450 grams per square meter under indoor growing with minimal care. In the hands of experts, the yield is around one gram per watt.

Indoor Flowering

When grown indoors, it needs roughly 9 weeks to fully mature, varying by about 5 days depending on the phenotype.

Outdoor Flowering

Harvesting occurs in mid-October for growers in the northern hemisphere, and by mid-April in the southern hemisphere.

Sativa/Indica Percentage

Indica 65% / Sativa 35%

La Huerta's Opinion

White Widow is a cornerstone of the Coffee Shop industry in the Netherlands, the strain that initiated the entire White family and one of the most successful cannabis strains in history.
