Black Widow Seeds

Black Widow isn’t just a cool name, it’s a warning. This sativa-heavy hybrid bites hard, wraps you in a thick cerebral web, then slowly pulls you under with its dreamy, full-body stone. The kind of smoke that starts with a cheeky grin and ends with you forgetting where you put your phone... and what a phone is.

Originally bred as the deadlier sister of White Widow, this is one of those strains that hits with serious intensity and keeps going. 28% THC? That’s not a gentle breeze. That’s a gust of pure potency. So if you’re after bold flavours, heavy effects, and resin-packed buds that glisten like they've just come out of the freezer, Black Widow’s your girl.

Short on time or space? Our Black Widow autoflowering version delivers solid results fast. No flipping the lights or second-guessing when to flower.

Strain Overview

Origin

Black Widow traces back to the original White Widow line, but with a darker twist. It’s a cross of South American and South Indian Sativa genetics, originally developed by the legendary breeder Scott Blakey (aka Shantibaba). When he left Green House Seeds and brought the genetics to Mr. Nice Seedbank, the original White Widow was renamed. Enter the Black Widow Fem. So yeah, there’s pedigree here. Not just marketing hype.

Effects & flavours

Don’t let the sweet fruit and pine on the nose fool you. This one comes with claws. The high is intense and fast-acting, with a brainy buzz that lifts the mood and ignites conversation. Great for creative sessions or chatting absolute nonsense with friends until sunrise.

But there’s a sneaky side to it. After that initial euphoria, the indica notes start crawling in. Limbs get heavy. Eyes start to droop. Suddenly that armchair is the best invention known to mankind. Hungry? Oh yes. Sleepy? Eventually, deeply.

Taste-wise, it’s complex. Think pine forest soaked in fruit juice, with a good whack of skunk and that classic woody aftertaste that lets you know it’s proper old-school weed.

THC & CBD Levels

With THC levels peaking at a formidable 28%, Black Widow is strictly adults only. This isn’t a strain you microdose. It’s the kind you respect. CBD sits at a mild 1.5%, just enough to round off the sharper edges and ease you gently into the body effects without cutting into the punch.

Terpenes

Black Widow’s terpene profile is led by alpha-pinene and beta-caryophyllene, giving it those crisp pine and spicy-skunky notes. Limonene adds a citrus brightness, while linalool and humulene provide depth, calming the buzz just enough to keep things enjoyable rather than overwhelming.

Growing Black Widow Seeds

Grow Difficulty

She’s surprisingly forgiving for such a strong strain. Great vigor in veg, strong branching, and dense colas in flower. Doesn’t throw tantrums if you mess up a feeding or two. In short, a solid choice for confident beginners who want a step up, or pros chasing a harvest that packs a serious punch.

Indoor vs. Outdoor Growing

Indoors, Black Widow Fem thrives under good lighting and is very responsive to training techniques. SCROG her out and you’ll be rewarded with big, resin-coated colas. Outdoors, she loves the sun. In warmer, drier climates, she goes all out. Tall, wide, and dripping with sticky bud. Just keep an eye on humidity during late flower, as her density makes her a bit mould-prone if things get soggy.

Greenhouses? Absolutely. It’s a great middle ground that lets her stretch and still stay protected from the elements.

Flowering Time & Yield

Expect flowering to last around 8 to 10 weeks indoors. Outdoors, you’re looking at a late September to early October harvest.

When it comes to yield, she pulls her weight. Indoor growers can expect between 500 grams per m2 and 700 grams per m2, while outdoors she can hit anywhere from 600 grams per plant to 800 grams per plant.

Height-wise, she’s no compact shrub. Indoors, you’re looking at plants that reach 120 cm to 160 cm. Outdoors, she stretches up to 140 cm to 200 cm, especially when given room and sunshine.
