Sirius Black is a dark, resin-forward indica-leaning cultivar shoppers hunt for peppery Black Domina character with Widow frost. The most commonly reported lineage on Kind Seed Co’s live table pairs Black Domina × White Widow. Expect dense, resinous flowers, earthy-citrus-kush jar notes, and a calm evening finish. Kind Seed Co is a reseller. Kind Seed Co did not breed the original cut.

What is Sirius Black?

In seed-bank language, Sirius Black usually means:

• An indica female with compact-to-average stature and heavy trichome coverage
• Dark or deep-green flowers that can read almost black in photos when resin and anthocyanins stack
• Catalog THC potential often listed around 25% on white-label pages
• Photoperiod flowering commonly 9-10 weeks after flip (some copy says ~8-10)

This page is a named cultivar profile. It is not a replacement for the broader Black Domina pepper-spice archive:

• Black strains family
• Feminized cannabis seeds
• Autoflower seeds
• Family strain hub
• How to germinate cannabis seeds

Lineage notes (commonly reported)

Most Kind Seed Co copy and related Black-shelf talk frame Sirius Black as:

• Black Domina: pepper-spice Afghani-line indica density, dark resin lore, caryophyllene bite in many family notes
• White Widow: classic Brazilian sativa × South Indian indica resin bomb. Frost, balance, and bag appeal in countless hybrid stories

Together they explain why Sirius Black listings emphasize dark, sticky flowers and a hybrid of physical calm with an early euphoric lift. When online databases disagree on parents, treat the live product table as the SKU you are actually buying, and treat encyclopedia stories as commonly reported context.

Seed packs are not clones. White-label vs branded Black-named packs can lean different on pepper vs berry vs citrus.

Aroma, flavor, and commonly reported effects

Notes that show up in product copy and grow talk:

• Nose: citrus, woody, fruity, kush. Berry-musk and spice in some descriptions
• Flavor: earthy pine and sweet citrus on many reports, with spice or light skunk on the exhale
• Feel: early uplift or creative buzz that settles into body calm. Many consumers save heavier indica-leaning flower for later hours

Kind Seed Co’s Sirius Black Photo Fem page lists THC potential up to 25% and CBD potential under ~1%. Those are catalog figures, not a promise for your garden. Start low. Nothing here diagnoses or treats a condition.

Grow notes for Sirius Black-type plants

Public summaries and the live white-label table usually point to:

• Structure: average height (~5 ft / 1.5 m in Kind Seed Co notes). Compact enough for tents when trained early
• Flowering (photoperiod): table lists 9-10 weeks after flip
• Yields (catalog ranges): indoor about 400-500 g/m². Outdoor about 400-500 g/plant
• Resin: the selling point for many keepers. Good airflow matters once flowers grease up
• Training: LST and selective defoliation for airflow. Support cola weight late flower
• Odor: woody-citrus-kush rooms still need filtration indoors

Practical checklist:

1. Confirm photoperiod fem before you build the calendar
2. Open the canopy mid flower so dark, dense tops dry between waterings
3. Watch RH in late bloom. Resinous indica flowers mold when tents stay wet
4. Cure patiently so citrus-wood terps do not collapse into generic earth

Technique hubs: boost yields indoors, how to grow bigger buds, soil feeding schedule. Germination steps belong on the germination guide.

Resin, airflow, and dark-flower myths

Dark calyxes photograph well, but Sirius Black keepers earn their place on frost and nose, not on Instagram charcoal alone. Dense Domina-leaning flowers need space between sites. Thin interior fluff early enough that late flower is about ripening, not emergency leaf stripping. Keep oscillating fans moving air across the cola faces, not blasting them.

Indoors, average height notes make this a workable tent plant when you train in veg. Outdoors, finish windows still depend on your latitude. A 9-10 week bloom after flip is not the same as seed-to-harvest outdoors. Odor is woody-citrus-kush, not candy, but it is still obvious through an open window.

When you want other Domina-shelf names after this cut, use the black strains archive. Keep this page focused on Sirius Black so it does not compete with that family hub.

Phenotype cues and who it fits

From seed, look for dark or deep-green calyxes with heavy frost, a peppery or woody-citrus jar, and stout branching that packs on weight in weeks 6-10. Select keepers after dry/cure. “Black” in the name is a family cue, not proof every cola photographs charcoal. Often a match if you want:

• Dark, resinous indica-leaning flower with Domina × Widow character
• A photoperiod run that finishes in roughly 9-10 weeks
• Evening-leaning calm with an early mood lift

Think twice if you want:

• Bright, racy daytime sativa spears with almost no body weight
• Stealth outdoor odor
• A full Black-family shopping list (use the black strains hub for siblings like Black Widow or Grandaddy Black)

Naming note (not a black-strains hub)

Sirius Black sits on the Black Domina pepper-spice shelf, but this article stays on the named cut. Sibling Domina kids and Widow cousins belong on black strains. Do not retitle this page as a color-shop or “best black strains” listicle.

FAQ

Is Sirius Black indica or sativa?

Kind Seed Co’s listing calls Sirius Black an indica. Effects reports often start uplifted and finish physically calm. Dose and tolerance still matter.

What is Sirius Black’s lineage?

The most commonly reported parents on Kind Seed Co pages are Black Domina × White Widow. Treat that as commonly reported retail lineage for the live white-label pack, not a courtroom pedigree for every bag labeled Sirius Black worldwide.

How long does Sirius Black flower?

The live white-label table lists about 9-10 weeks after flip. Confirm timing on the product page at purchase.

Does Kind Seed Co breed Sirius Black?

No. Kind Seed Co is a reseller. The live pack is Weed Seeds Usa White Label stock with traits aimed at the named cultivar, not an in-house breeding claim.
