Black Widow Strain Genetics

This folks is not just a comic character but a weed strain with genetics worthy of a superhero backstory.

Origins and Lineage

Origins and Lineage

Hailing from the land of samba and soccer, Brazil, and the enchanting South Indian region, the Black Widow is a hybrid strain crafted by the masterminds Scott (Shantibaba) Blackey and Arjan Roskam.

Shantibaba, who is also known as one of the creators of the iconic Critical Mass strain and Super Silver Haze, collaborated with Arjan under the guise of Greenhouse Seeds and Mr. Nice Seeds to bring forth this remarkable hybrid.

This is a descendant of an exotic Brazilian sativa and a robust South Indian indica.

But unlike Spiderman, it didn’t need a radioactive spider to get its superpowers. Its parents passed those down – naturally.


The Black Widow didn’t just crawl out of its web one day and declare itself the champion of the cannabis world.

It earned its stripes in 1995 when it snatched the Number One spot from White Widow strain at the High Times Cannabis Cup.

Since then, it’s been luring cannabis enthusiasts into its web from the legal markets of California, Colorado, Oregon, Washington State, and Michigan.

The Appearance of Black Widow Weed

Like its namesake, the Black Widow carries a dark, menacing allure.

Its purple-tinged, dense frosty buds glisten with a thick layer of crystalline trichomes.

Its dark green leaves, speckled with fiery orange hairs, capture the eye and hint at the explosive experience to come.

Is Black Widow Indica or Sativa?

Is Black Widow Indica or Sativa

The Black Widow is a master of disguise, a hybrid leaning toward either sativa-dominant or slightly indica-dominant side.

But regardless of its sativa/indica ratio, this strain always promises a wild ride.

Expect an initial burst of sativa-like energy and euphoria followed by waves of indica-inspired relaxation.

Cannabinoids and Terpenes

Cannabinoids and terpenoids are the dynamic duos behind every high.

Terpenes Profile

This strain boasts a dominant terpinolene profile, supported by secondary ocimene and limonene terpenoids.

The terpinolene leads with a fruity and herbal punch, the ocimene adds a sweet, woodsy undertone, and the limonene finishes with a refreshing citrus twist.

THC and CBD levels

With THC levels ranging from 18% to 28%, it is not for the faint-hearted.

The average THC content hovers between 20% and 25%, promising a potent and long-lasting high.

As for CBD, the levels are low, but who needs it when the tetrahydrocannabinol is partying hard?

Aroma and Flavor

The flavor echoes the smell, a delicious combination that will bring you back for more.

Black Widow Strain Effects and Medical Benefits
