Kosher Kush
A pungent indica-leaning strain from DNA Genetics with murky origins, a loyal following, and a strong Cup pedigree.
Kosher Kush is a real, well-documented DNA Genetics release with legitimate awards, including High Times Cannabis Cups in 2010 and 2011. Beyond that, most of what you'll read is marketing. Its lineage is officially undisclosed — 'a secret Los Angeles clone' — so anyone claiming to know the parents is guessing. Effects reports are anecdotal, not clinical. It's a solid, heavy, kush-type plant. Whether it hits any harder than other quality OG-type flower is a matter of chemotype and dose, not the name.
Overview
Kosher Kush is an indica-dominant cultivar released by Amsterdam-based DNA Genetics. According to the breeder, it originated as a clone circulating in Los Angeles that was blessed by a rabbi — hence the name — and was then stabilized into seed form for release [1][2]. It won High Times Cannabis Cup awards for Best Strain (2010) and Best Indica (2011) [2], which is a large part of why the name has staying power in seedbank catalogs.
The plant is known for a heavy, resinous structure, a pungent earthy-citrus smell in the OG/Kush family, and a sedating reported effect profile. Beyond those broad strokes, most claims about Kosher Kush are marketing or anecdote rather than tested fact.
Chemistry
There is no published peer-reviewed chemotype study specifically on Kosher Kush. Reported ranges come from breeder marketing and dispensary lab panels, which vary widely by grower, phenotype, and lab methodology Weak / limited.
- THC: Commonly listed in the 18–22% range by weight in dried flower, with some phenotypes reported higher [1].
- CBD: Effectively negligible, typically under 0.5%, consistent with the broader OG/Kush family Weak / limited.
- Terpenes: Dispensary panels frequently list myrcene as dominant, with beta-caryophyllene and limonene as secondary. This matches the general pattern seen in Kush-family cultivars in published chemotype surveys [3], but has not been confirmed for Kosher Kush specifically in peer-reviewed work.
A note on folklore: the claim that myrcene above 0.5% flips a strain to 'couch-lock' is popular online but is not supported by controlled human research Disputed. Terpene effects at inhaled cannabis doses are not well characterized in humans [4].
Reported effects
Important caveat: There are no clinical trials of Kosher Kush or, indeed, of nearly any named cannabis strain. What follows is aggregated user report, not evidence Anecdote.
Users commonly describe Kosher Kush as heavy-bodied, sedating, appetite-stimulating, and useful for sleep. Reviews on consumer databases skew toward late-evening use. These reports are consistent with a high-THC, low-CBD, myrcene-forward chemotype but should not be treated as predictions for any individual.
The broader scientific picture: strain name is a poor predictor of chemistry, and chemistry is only a moderate predictor of subjective effect. Set, setting, tolerance, and dose dominate outcomes [4][5]. The indica/sativa label — including Kosher Kush's 'indica-dominant' tag — does not reliably predict effects in controlled studies [5] Strong evidence.
Lineage
The honest answer: nobody outside DNA Genetics knows the parents, and DNA Genetics has not disclosed them. The breeder describes Kosher Kush as originating from an unnamed Los Angeles clone [1][2].
Seedbank and wiki entries that list specific parents (various OG Kush crosses, Afghani lines, etc.) are speculation. Some are plausible given the phenotype and smell, but none are confirmed. Treat any confident lineage claim about Kosher Kush as folklore unless it comes from DNA Genetics directly Disputed.
DNA Genetics has since released several derivatives — Kosher Tangie, Kosher Dawg, and the autoflowering Kosher Kush Auto — where the crossing partner is documented [1].
Cultivation basics
Based on the breeder's grow notes and grower reports [1] Weak / limited:
- Flowering time: 9–10 weeks indoors; outdoor harvest late October in the Northern Hemisphere.
- Structure: Medium-height, branchy, with dense internodes typical of Kush genetics. Responds well to topping and low-stress training.
- Yield: DNA Genetics reports around 450–500 g/m² indoors under competent conditions. Outdoor plants can be substantially larger.
- Environment: Prefers a drier finish; susceptible to bud rot in humid climates because of dense flower structure.
- Feeding: Handles moderate to heavy feeding; not particularly finicky.
- Difficulty: Moderate. Not a beginner-only plant, but not notoriously fussy either.
The original cut is a clone-only line in some circles; DNA Genetics' seeds are the stabilized F1 version and will show phenotype variation.
Marketing vs. reality
A few claims worth separating:
- 'Blessed by a rabbi': This is DNA Genetics' origin story [1][2]. It is a marketing narrative, not a product certification. There is no kashrut certification system for cannabis flower, and no major kosher-certifying agency certifies inhaled cannabis. Some agencies (e.g. OU) have certified specific cannabis-adjacent edible products, which is unrelated [6].
- 'Won the Cannabis Cup, so it must be the strongest': The Cannabis Cup is a judged competition, not a potency test. Winning means judges liked a specific submitted sample — not that the strain is uniformly more potent than others [2].
- 'Pure indica': The chemovar concept and multiple genetic studies show that consumer indica/sativa labels don't map cleanly onto genetics or effects [5][7] Strong evidence.
- 'Kosher = cleaner/healthier': There is no evidence Kosher Kush is grown to any different agricultural standard than other DNA Genetics releases. Cleanliness depends on the individual grower and lab testing, not the name.
