Kosher Kush
Kosher Kush is the DNA Genetics-released seed-form version of a Los Angeles clone-only cut originally known as Jew Gold, brought to seed in the early 2010s and quickly recognized with back-to-back High Times Cannabis Cup wins in 2010 and 2011 in the indica category. The strain anchors the heavier-indica side of the modern Kush family and is widely cited as one of the most potent indicas available in commercial seed form. Plants finish in nine to ten weeks indoors with dense, dark-green buds and a thick trichome layer that develops in the back half of flower. The flavor leans earthy and fuel-forward with a slight pine and floral note, and the high is heavy, slow, and deeply sedating — most reviewers describe it as a strict bedtime strain.

Terpene profile
The aromatic compounds below shape how Kosher Kush 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
Linalool
Floral and lavender-like — calming, often noted for sleep and anxiety support.

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

Feed schedule for Kosher Kush
These EC and NPK targets are starting points calibrated for the strain's Indica lean and moderate 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
- 1.4-1.6 EC
- Early flower
- 1.5-1.7 EC, NPK 2-3-4
- Mid flower
- 1.8-2.0 EC, NPK 1-4-6
- Late flower
- 1.6-1.8 EC
- Final week
- Plain pH-balanced water for the last 7-10 days; light flush if you ran nutrients on the higher end.

What to expect through the grow cycle
Kosher Kush is documented with a 10-week flower and a compact stretch typical of indica-leaning structure. The visual below maps a documented 14-week cycle built from 4weeks of vegetative growth and the strain's published flowering window.
Published grow reports for Kosher 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 Kosher Kush. Plants establish root structure, leaf canopy, and node count before flower triggering, with a moderate difficulty rating shaping how forgiving the early canopy work tends to be.
- Stretch (weeks 5-8)
- Kosher Kush is documented as having moderate stretch. Reports describe the plant roughly doubling in height during this phase as the indica-leaning structure establishes its final flowering frame.
- Bud sites (weeks 9-10)
- Pre-flowers form at the nodes and calyxes begin to develop. Grow reports for Kosher Kushnote this as the window where the canopy's eventual bud distribution becomes visible.
- Bud development (weeks 11-12)
- Flowers thicken and calyxes fatten through this phase. Documented Kosher Kush runs show the bulk of visible flower mass accumulating here, with resin production accelerating toward the end.
- Ripening (week 13)
- Trichomes transition from clear toward cloudy and amber. Reports for Kosher Kush describe the Myrcene-led terpene profile maturing through this window, with aroma sharpening week over week.
- Final (week 14)
- Calyx swelling is documented as complete and the harvest window opens. Published Kosher Kush runs end here, within the 9-10 week flowering range reported by the breeder.

Common questions about Kosher Kush
Did Kosher Kush really win two Cannabis Cups in a row?
Yes — Kosher Kush took first place in the indica category at the High Times Cannabis Cup in both 2010 and 2011, one of the rare back-to-back indica wins in the Cup's history.
Is Kosher Kush stronger than OG Kush?
Modern Kosher Kush phenotypes typically test 1-3 percent higher in THC than straight OG Kush and produce a noticeably heavier, more sedating effect. Most reviewers describe Kosher Kush as a strict bedtime strain rather than the more flexible OG.
