Sirius Black Strain Info

Sirius Black is a feminized photoperiod strain with a 40% Sativa/60% Indica ratio and 15-25% THC. This mostly Indica hybrid is known for its unusually dark appearance, with the source text calling it one of the darkest strains available. The effect profile leans creative and energetic, yet the Indica side gives the experience a calmer undertone as it develops. Its flavor moves from citrus and fruit toward a Kush-wood finish, creating a profile that feels bright on top and deeper underneath. Growers can expect medium yields, steady performance, and strong resin appeal when conditions stay dialed in.

Genetics

Sirius Black comes from secret strains, which fits the name a little too perfectly. The source text links its wider background to global genetics and OG Kush heritage, giving the strain its sturdy hybrid character and richer aromatic base. Because the exact parents are not disclosed, the best clues come from its behavior: dark flowers, resin-heavy buds, Kush depth, and a balanced effect that starts brighter than many Indica-leaning cultivars.

Flowering Time

Sirius Black flowers in 63-70 days, or about 9-10 weeks indoors according to the source text. This moderate schedule gives the plant enough time to develop dense flowers and strong aroma. Growers should keep late bloom dry and well-ventilated, especially as resin coverage increases and the buds become more compact.

Yields

Indoors, Sirius Black can produce around 1.3-1.6oz/ft² (400-500g/m²). Outdoors, growers can expect approximately 14.1-17.6oz (400-500g) per plant in suitable conditions. The yield range is steady rather than oversized, but the visual appeal and dark flower character help make the harvest feel special.

Effects

The high begins with an energetic mental lift that gives the session a brighter pace. Creativity follows naturally, making Sirius Black useful when ideas need a little spark without turning the room chaotic. Euphoria adds a smoother mood shift as the effect develops, while the 60% Indica side keeps everything from floating too far away. It works well for evenings that need imagination, comfort, and just enough gothic drama to keep things interesting.

THC and CBD Levels

Sirius Black contains 15-25% THC. This range gives the strain flexible potency, with a more moderate feel at the lower end and a stronger experience when it reaches its ceiling. The 60% Indica structure helps shape a smoother finish, while the 40% Sativa share supports the creative opening.

Smell and Taste

The flavor opens with citrus, then fruity sweetness gives the smoke a brighter middle. Kush depth follows on the finish, with woody notes adding a darker and more grounded tone. The source text also mentions sweet caramel grape, dark berries, and musky hashish in the aroma. That makes Sirius Black feel layered and moody, like a fruit bowl left in a very dramatic library.

Grow Tips

Sirius Black is moderately easy to grow and hardy, though pest prevention remains important. Plants reach about 4.9ft (150cm), making them manageable indoors with basic canopy control.

• Use ScrOG indoors to improve light spread and support lower flower growth.
• Keep temperatures around 68-77°F (20-25°C) for stable development.
• Lower RH from 55-60% in veg to around 40% during flowering.
• Choose perlite, peat, or coco coir for balanced moisture retention.
• Outdoors, sow in April in the Northern Hemisphere for a mid-October harvest.
