Black Domina
Black Domina is the Sensi Seeds indica project released in 1998 as a four-way Afghani-leaning cross combining Northern Lights, Ortega, Hash Plant, and an Afghani SA line — all narrow-leaf indica backgrounds selected for resin, structure, and short flowering. The plants finish in roughly seven to eight weeks indoors with squat, branchy structure and dense, dark-green to near-black foliage that gives the strain its name, and the bud expression is heavily Afghan with peppery hash, fresh-ground coffee, and earth-spice on the inhale. The high is one of the heaviest indica sedative profiles in the Sensi catalogue, suiting evening use and chronic pain management rather than functional daytime consumption. Black Domina was one of the first commercial indica lines bred specifically for narrow-leaf hash production rather than dual-purpose dry-flower yield, and Moroccan and Afghan hash producers picked up the line through the early 2000s. The Sensi version remains the canonical commercial release, with smaller selection projects working off the same four-way background still circulating among preservation growers.

Terpene profile
The aromatic compounds below shape how Black Domina smells, tastes, and ultimately feels in the body.
- dominant
Myrcene
Sedating, musky, herbal — commonly linked to couch-lock effects.
- secondary
Caryophyllene
Peppery and spicy — the only terpene that binds CB2 receptors, studied for anti-inflammatory action.
- secondary
Humulene
Hoppy and earthy — appetite-suppressing and shared with hops and sage.
- minor
Pinene
Alert and pine-forward — associated with mental clarity and bronchodilation.

Lineage
Black Domina traces to Northern Lights × Ortega × Hash Plant × Afghani SA. The cross sits in the Afghan indica family, which influences both the terpene profile and the flowering structure described above.

Feed schedule for Black Domina
These EC and NPK targets are starting points calibrated for the strain's Indica lean and easy difficulty rating — not gospel. Drop 15-20% off any EC ceiling on your first run and let the plant tell you where it actually wants to feed.
Suggested feed schedule
- Late veg
- 1.1-1.3 EC
- Early flower
- 1.2-1.4 EC, NPK 2-3-4
- Mid flower
- 1.5-1.7 EC, NPK 1-4-6
- Late flower
- 1.3-1.5 EC
- Final week
- Plain pH-balanced water for the last 5-7 days.

What to expect through the grow cycle
Black Domina is documented with a 8-week flower and a compact stretch typical of indica-leaning structure. The visual below maps a documented 12-week cycle built from 4weeks of vegetative growth and the strain's published flowering window.
Published grow reports for Black Domina concentrate the most observational notes on the late-flower ripening window. This timeline is descriptive — it reflects what reports document, not a how-to. Actual week-to-week behaviour varies with phenotype, light intensity, pot size, and environment.
Phase details
- Veg (weeks 1-4)
- The documented vegetative period for Black Domina. Plants establish root structure, leaf canopy, and node count before flower triggering, with a easy difficulty rating shaping how forgiving the early canopy work tends to be.
- Stretch (weeks 5-7)
- Black Domina is documented as having low stretch. Reports describe the plant roughly doubling in height during this phase as the indica-leaning structure establishes its final flowering frame.
- Bud sites (week 8)
- Pre-flowers form at the nodes and calyxes begin to develop. Grow reports for Black Dominanote this as the window where the canopy's eventual bud distribution becomes visible.
- Bud development (weeks 9-10)
- Flowers thicken and calyxes fatten through this phase. Documented Black Domina runs show the bulk of visible flower mass accumulating here, with resin production accelerating toward the end.
- Ripening (week 11)
- Trichomes transition from clear toward cloudy and amber. Reports for Black Domina describe the Myrcene-led terpene profile maturing through this window, with aroma sharpening week over week.
- Final (week 12)
- Calyx swelling is documented as complete and the harvest window opens. Published Black Domina runs end here, within the 7-8 week flowering range reported by the breeder.

Common questions about Black Domina
Why is Black Domina called black?
The leaves and bract foliage darken to a near-black green during late flowering under cool nighttime temperatures, especially in the final two weeks. The trait comes from the Afghani SA parent and is a marker for the high-resin Afghan indica background.
Is Black Domina suited to small grow spaces?
Yes — the plant stays squat at 70 to 110 cm indoors with low stretch and a short seven to eight week flowering window, which makes it one of the better fits for tents under 1.2 meters or for closet grows where vertical space is the limiting factor.
