Master Kush
Master Kush is the Sensi Seeds release of an Amsterdam-stabilized Hindu Kush working line crossed with a second Afghani landrace, originally released in the early 1990s and recognized with a High Times Cannabis Cup win in 1992. The strain has stayed in the Sensi catalogue continuously since release, anchoring the pure-indica side of the brand alongside Northern Lights and Hindu Kush. Plants stay short and dense, finish in seven to eight weeks, and produce thick layers of trichome resin that make them favorites for traditional hashish production. The high is heavy and meditative, with a citrus-earth terpene profile that distinguishes it from straight Hindu Kush and a body effect that runs deep without overwhelming the head.

Terpene profile
The aromatic compounds below shape how Master Kush smells, tastes, and ultimately feels in the body.
- dominant
Myrcene
Sedating, musky, herbal — commonly linked to couch-lock effects.
- secondary
Limonene
Uplifting citrus — typically associated with mood elevation and stress relief.
- secondary
Caryophyllene
Peppery and spicy — the only terpene that binds CB2 receptors, studied for anti-inflammatory action.
- minor
Humulene
Hoppy and earthy — appetite-suppressing and shared with hops and sage.

Lineage
Master Kush traces to Hindu Kush × Afghani. The cross sits in the Kush / Afghan family, which influences both the terpene profile and the flowering structure described above.

Feed schedule for Master Kush
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
Master Kush 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 Master Kush 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 Master Kush. 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)
- Master Kush 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 Master Kushnote 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 Master Kush 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 Master Kush 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 Master Kush runs end here, within the 7-8 week flowering range reported by the breeder.

Common questions about Master Kush
Is Master Kush the same as Hindu Kush?
No — Master Kush is a Sensi Seeds cross that uses Hindu Kush as one parent and a second Afghani landrace as the other. The terpene profile leans more citrus and the high is slightly less sedating than pure Hindu Kush.
Is Master Kush beginner-friendly?
Yes. It stays under 110 cm indoors, finishes in seven to eight weeks, resists pests and mold, and forgives nutrient mistakes. It is one of the most recommended beginner indicas in the Sensi catalogue.
