Get caught in the chaos of Black Widow Auto. This isn’t just a plant, it’s a personality. Fast, fruity, and full of bite, she’s ready to spark your grow and light up your stash jar.
Black Widow Auto doesn’t tiptoe into the room. It strides in, confident and wired with sativa energy. This is the autoflower version of a certified heavy-hitter, and while it may be a bit more manageable than its photoperiod sibling, don’t let that fool you. The bite is still there.
Expect a punchy cerebral high that wakes up your thoughts, gets the chatter flowing, and might even push you to tackle that creative project you’ve been ignoring. Then, just as you’re soaring, it eases you down with a subtle body buzz that’s more grounding than gluey. Fast, fierce, and surprisingly fruity, Black Widow Auto is a potent choice for those who like their weed to have personality.
If you’ve got the time and want to push yields to the limit, the Black Widow photoperiod version brings the full grower’s toolkit to the table.
Black Widow Auto stems from the legendary Black Widow. That strain was itself a darker, more intense take on the original White Widow line. This autoflowering version was created by crossing Black Widow with a hardy Ruderalis, cutting down the grow time without trimming the attitude. You still get that resin-soaked punch and iconic profile, but in a format that’s fast, easy, and beginner-friendly. A true modern spin on a ‘90s heavyweight.
The effects kick in quickly, starting in the head with a sharp jolt of mental clarity and euphoria. It’s social, creative, and energizing. A solid day smoke if you're not planning on napping anytime soon. After the initial buzz, there’s a gentle lean into relaxation, but it never turns heavy.
Flavor-wise, it’s a pleasant surprise. You get sweet, skunky pine upfront, backed by earthy berry and a subtle woody richness. Classic with a twist. Like someone threw a fruit basket into a forest bonfire, in the best way.
Black Widow Auto clocks in around 19% THC, which is more than enough to put less experienced users on notice. It’s strong without being overwhelming, and nicely balanced by 0.6% CBD to soften any edge. Not one to underestimate, but not an instant couch-trap either.
Terpinolene leads the charge here. It's floral, fresh, and slightly piney, with support from limonene, myrcene, and linalool. That combo brings a bit of zip, a hint of calm, and plenty of aroma. It’s what gives Black Widow Auto that fresh-yet-funky personality, kind of like it just rolled out of the woods wearing berry cologne.
This one’s ideal for growers who want power without the headaches. Thanks to its autoflowering nature, it doesn’t need any light schedule trickery. It’s also pretty resistant to common pests and stress. Whether it’s your first run or your fiftieth, Black Widow Auto is a solid, low-maintenance option.
Black Widow Auto fits nicely indoors. Compact, fast, and discreet. Perfect for tents, cupboards, or stealth setups. Indoors, plants stay between 50 cm and 90 cm. Outdoors, expect slightly more stretch, around 70 cm to 110 cm. It’ll thrive in Mediterranean to temperate climates, especially when given a bit of protection from heavy rains. Greenhouses? Even better. You’ll get the resin production and terpene richness of a photoperiod widow, just with less hassle.
Expect flowering to last between 56 and 70 days, with harvests that lean generous for an auto. Indoors, yields typically fall between 350 grams per m2 and 400 grams per m2. Outdoors, she’ll put out between 175 grams per plant and 210 grams per plant, especially with a good feed and solid sun. This isn’t one of those skimpy autos; she brings both weight and quality.
If you're after a sativa-dominant autoflower that’s as punchy as it is productive, Black Widow Auto delivers. Quick to flower, rich in flavor, and loaded with classic genetics, she’s got all the kick of the original Widow with way less waiting around.

Got my seeds a few months ago, and now I’m chilling with my first Black Widow auto harvest. The grow was smooth, and they didn’t take up much space, which was a plus since I’ve got a pretty small grow area. Plants stayed healthy throughout, didn’t even need much maintenance.
All the seeds popped quick, and the plants grew thick with resin-covered buds. Harvested way more than I thought. Definitely a solid strain for anyone wanting a smooth grow.
I just randomly bought these autos, and right off the bat, I had a great germination rate, 9 out of 10 seeds sprouted., he growing process was pretty straightforward.
