Black Widow Feminised

What Is Black Widow Feminised?

Black Widow Feminised traces back to one of the most celebrated names in modern cannabis breeding. Growers still reach for it today because it backs up that reputation with a genuinely potent, resin-heavy result.

Breeders crossed a Brazilian Sativa with a South Indian Indica to create the line. That pairing gives it real depth: a sativa-leaning structure paired with the resin production and stability of a strong indica backbone. That exact combination made the original version a Cannabis Cup winner.

What makes this version stand out is how well it has held up. Decades after its debut, it still delivers a coating of resin and a euphoric, clear-headed high that few newer strains manage to match.

Origins & Genetics of Black Widow

Black Widow Feminised comes from a Brazilian Sativa and South Indian Indica cross. Shantibaba created the original line in Amsterdam during the 1990s. It won 1st Place for Best Flowers at the 1995 High Times Cannabis Cup, a result that helped cement its reputation. Shantibaba’s own seed listing adds an extra layer of history. It first went to market as White Widow, and he renamed it Black Widow after founding Mr Nice Seedbank. That’s a useful detail if you come across both names while researching this cross.

Most sources agree on this parentage and a sativa-leaning phenotype, generally putting the split around 65% sativa to 35% indica. One prominent seed bank instead lists a different four-way lineage. It points to Colombian Gold, Thai and Mexican genetics with some Afghani heritage, and calls the result sativa-dominant rather than giving an exact split. Always check which version a listing describes before comparing reviews or grow reports.

This cross has circulated among several seed banks since the 1990s. So its core character stays fairly consistent, even where the exact parent chain varies by source.

Black Widow Effects, Aroma & Flavour

Users commonly describe a euphoric, clear-headed onset that sharpens focus and lifts mood before easing into deep, full-body relaxation as the high develops. Some reports lean more heavily on the calming side from the start, so individual results can vary.

The aroma leans sweet and fruity, with skunky, earthy undertones and a subtle spicy edge rounding it out.

Humulene, linalool and limonene lead the terpene profile in most reports. Our guide to maximising terpenes is a useful companion read if you want to preserve that fruity-sweet flavour through curing.

Growing Black Widow Seeds

This strain rates as moderately easy to grow. Its stable, hardy genetics make it a realistic option for a first-time grower, though it rewards the extra attention an experienced grower can offer.

Indoors, its structure responds well to a Sea of Green setup, and it holds up reliably under a standard vegetative and flowering regime. Our guide to growing cannabis indoors in Australia covers the setup basics if you’re planning an indoor run.

Outdoors, this strain does well in a warm, sunny climate with a full season to finish. Our Australian cannabis grow calendar is a useful companion read for timing an outdoor planting correctly.

Black Widow Flowering Time & Yield

Black Widow Feminised typically finishes flowering in 8 to 10 weeks. Indoors, expect yields of around 350 to 450 g/m² under good conditions.

Outdoors, a healthy plant typically produces somewhere between 300 and 600g, assuming reasonable light, space and a full season. As always, actual results depend on light, nutrients, training and how well you manage the grow overall.

Treat those figures as a solid planning benchmark rather than a guaranteed outcome. Because this strain has such a long breeding history behind it, growers across many seed banks have refined its grow profile over decades.

Who Black Widow Seeds Suit Best

This strain suits growers chasing a genuinely potent, resin-heavy classic with real breeding pedigree behind it. It also suits users after a euphoric, clear-headed lift that eases into relaxation rather than heavy sedation from the outset. Growers with a little prior experience will get the most consistent results, though a careful first-timer can manage it too.

On the other hand, it’s a less natural fit for anyone chasing a fully beginner-proof grow or a strain that skips straight to deep sedation. If you’d prefer a similarly potent classic with an easier learning curve, Big Bud Feminised is worth a look. For anyone after a genuinely storied, high-resin sativa-leaning hybrid, though, Black Widow Feminised is hard to beat.
