Kush #5
A widely reused name with no single documented origin or consistent chemistry.
Growing, buying or possessing cannabis and seeds is legal only in some places. Check the law where you live before acting on this information.
Kush #5 is a name — not a fixed strain. Different growers use the same name for unrelated plants, usually claiming Kush ancestry. No breeder, seedbank or lab has published a standard definition. If you see it for sale, trust the Certificate of Analysis for that batch, not the label. Strain names alone are poor predictors of effects.
What we know
Kush #5 is a name used by cannabis growers and retailers, often advertised as a Kush-descended cultivar. There is no published breeder record, seedbank release, genetic study, or authoritative source that defines what Kush #5 actually is No data. No single plant or genotype is universally recognized by this name.
The name appears on dispensary menus and in online forums, typically described in the same language used for other Kush products: relaxing, body-oriented, sleep-promoting. However, these descriptions reflect consumer expectations for anything labeled 'Kush' rather than qualities measured or documented for this specific cut Anecdote.
Why numbered phenotype names matter — and why they don't travel well
In cannabis breeding, growers sometimes select multiple phenotypes from a seed run and label them numerically: '#1', '#3', '#5'. The number is meaningful only within that breeder's project — it is shorthand for their own detailed notes [1][2].
Once a numbered name enters the wider market (through clones, resales, or loose information sharing), it loses connection to the original breeder's meaning. A second grower hears about 'Kush #5' and either receives a different clone under that name or simply uses the label for an unrelated plant. This pattern is well documented across the wider cannabis nomenclature Strong evidence [1][2].
The result: two jars labeled 'Kush #5' may come from completely different genetic lines, with different cannabinoid and terpene profiles, grown in different conditions.
Chemistry: what the label does not tell you
There is no published chemotype dataset for Kush #5 No data. Broader surveys of Kush-descended products in legal markets show that they tend to be THC-dominant (CBD typically <1%) with terpene profiles often led by β-myrcene, α-pinene, limonene, or β-caryophyllene, though the specific balance varies widely by line [3].
If you encounter a Kush #5 product with a Certificate of Analysis (COA), the COA represents that specific batch—not the name. Two products with identical labels can have meaningfully different cannabinoid and terpene numbers because they are, in practice, different plants Strong evidence [1][2].
Lineage and parentage
Claims about Kush #5's parentage are disputed and unverified Disputed. Common vendor statements include descent from OG Kush, Hindu Kush, Bubba Kush, or crosses involving these lines. None of these claims are backed by verifiable breeder records or genetic testing.
Genetic studies of commercially labeled 'Kush' products show that many do not cluster by name; the 'Kush' label is often applied more for marketing appeal than as a genetic descriptor Strong evidence [1][2]. Without a published pedigree from a named, documented breeder, any lineage tree for Kush #5 should be read as folklore, not fact.
Reported effects and why strain names don't predict them
Online reviews and dispensary descriptions of Kush #5 use familiar Kush language: body-heavy, sedating, sleep-friendly, relaxing Anecdote. These descriptions mirror general consumer expectations for anything called 'Kush' rather than qualities specific to this undocumented cut.
There are no strain-specific clinical trials for Kush #5, and no clinical studies isolating effects by strain name alone for any cannabis product Strong evidence. Peer-reviewed evidence shows that indica/sativa labels and strain names are poor predictors of subjective experience; chemotype (cannabinoid and terpene content) and individual dose tolerance predict effects far more reliably [4][5].
Expect variation between batches and between people.
How to evaluate Kush #5 if you encounter it
If a retailer or grower is selling a product labeled Kush #5, here is what to check:
Trust:
- The Certificate of Analysis (COA) for that specific batch (cannabinoids, terpenes, contaminant testing).
- Your own smell, appearance, and small test dose.
- The retailer's and cultivator's documented track record.
Do not trust:
- The strain name alone to predict effects Strong evidence.
- Vendor grow specifications or THC/CBD claims unsupported by lab testing.
- Numbered phenotype labels to be consistent across different sellers Anecdote.

Frequently asked questions
Is Kush #5 indica or sativa? The Kush family is typically classified as indica, but strain names and indica/sativa labels are unreliable predictors of effects. Without documented genetics or chemotype data for this specific cut, the label is not meaningful.
What is the THC level? Not documented. Products sold as Kush #5 vary widely. Check the Certificate of Analysis (COA) for the batch you are considering.
How long is the flowering time? Not documented. Anecdotal reports on forums describe Kush #5-labeled cuts flowering in 8–9 weeks indoors, but this is not verified and will vary by actual genetics and growing conditions.
Who bred Kush #5? Not documented. No established breeder or seedbank has published a definitive record. The name is used by multiple unrelated growers and retailers.
