Sirius Black

Why you should buy Sirius Black seeds

Sirius Black isn’t just a pretty name. It’s a heavyweight indica-dominant strain that delivers knockout flavor, stunning bag appeal, and a high that walks the line between deeply relaxing and energetically creative. Whether you're looking to melt into the couch or drift off on a wave of citrusy euphoria, Sirius Black brings the goods in style.

Perfect for growers chasing something with bold terps, solid resistance, and a compact structure that doesn't compromise on yield, this one shines in just about any setup. It’s forgiving, flavorful, and absolutely drenched in trichomes by the end of bloom. And the aroma? Let’s just say your carbon filter better be on point.

Strain Overview

Origin

The exact lineage of Sirius Black is shrouded in a bit of mystery, but what’s clear is its Oregon-born reputation for dark purple buds and rich, fruity aromas. Originally championed by the folks at Oregon Breeders Group, this strain has grown from cult favorite to modern classic. It’s indica-leaning through and through, with just enough sativa in the mix to keep things interesting upstairs.

Effects & Flavors

Take the first hit and you’re greeted with a burst of citrus and earthy chocolate, followed by sweet fruit and kushy depth. There’s a zesty lemon skunk kick in the nose too, wrapped in a pungent, woody undercurrent that makes each toke feel like a sensory detour through a dense fruit grove and a funky spice market.

Effect-wise, Sirius Black doesn’t mess around. The high is fast acting and powerful, starting with a wave of happy, uplifting energy before sliding smoothly into a deep calm. Depending on your mood and dose, it can make you feel creative and talkative or gently lull you into sleep. A true all-rounder.

THC & CBD Levels

With 25% THC and just 0.05% CBD, Sirius Black hits hard and fast. This is one for those who like their weed strong, flavorful, and full bodied. It's got the punch for seasoned smokers but manageable enough in smaller doses for those still finding their footing.

Terpenes

Sirius Black is a terpene buffet, led by terpinolene, beta-caryophyllene, and linalool, with backup from limonene, cymene, phytol, borneol, and a whole crew of supporting players like valencene, eucalyptol, and the pinene twins (alpha and beta). The result is a flavor profile that’s floral, fruity, spicy, and just a touch herbal and minty, with mood-lifting and body-soothing effects to match.

Growing Sirius Black Seeds

Grow Difficulty

Sirius Black is well suited to both beginners and experienced growers. It’s not the type to throw tantrums if conditions aren’t perfect. With medium to high fungal resistance and a solid growth structure, she rewards even laid-back growers with dense, resin-caked colas.

Indoor vs. Outdoor Growing

Indoors, she stays nice and compact, between 31 inch and 47 inch, making her great for tents and stealth setups. Outdoors, she can stretch up to 59 inch, typically ranging between 47 inch and 59 inch, and thrives in a wide range of climates. From warm Mediterranean gardens to temperate greenhouses and even cooler polar zones if you're pushing your luck, she holds up well. Just make sure she gets good light and airflow and you’ll be golden.

Flowering Time & Yield

Sirius Black takes about 56 to 63 days to flower, which is pretty reasonable for something with this much flavor and weight. Indoors, expect yields in the ballpark of 1.3–1.6 oz per square feet. Outdoors, with a bit of space and sunshine, she can push out a hefty 24.7–31.7 oz per plant. Not bad for a plant that stays relatively modest in height.
