Kush #4

Overview

Kush #4 is a name that appears sporadically in cannabis retail menus and grower forums, typically presented as a numbered phenotype selection from a broader Kush line. Unlike well-catalogued cultivars such as OG Kush or Hindu Kush, Kush #4 does not have a widely accepted origin story, breeder of record, or published chemistry profile No data.

Numbered 'pheno hunt' names like #4, #7, or #11 are common in modern breeding: a breeder pops a pack of seeds, keeps the plants they like, and assigns numbers. Without provenance documentation, two different sellers offering 'Kush #4' may be selling genetically unrelated plants. That is the single most important thing to understand about this name.

Chemistry

There is no peer-reviewed or government lab dataset that specifically characterizes 'Kush #4' as a distinct chemotype No data. Broad surveys of Kush-labeled flower on legal markets show that most Kush cultivars cluster as THC-dominant (typically 15–25% total THC) with negligible CBD (<0.5%), and terpene profiles skewed toward β-myrcene, α-humulene, β-caryophyllene, and limonene ^[1][2] Strong evidence.

Whether any given Kush #4 sample fits that pattern depends entirely on the specific cut and grower. The only reliable chemistry information is the certificate of analysis (COA) attached to the batch you're actually buying. Do not assume a name predicts cannabinoid or terpene content — Smith et al. and others have shown that strain names correlate poorly with underlying chemistry ^[1] Strong evidence.

Reported effects

Vendor and forum descriptions of Kush #4 lean on the standard 'indica-heavy, relaxing, sedating, good for sleep' script that applies to nearly every Kush-branded product Anecdote. There are no controlled human studies of this cultivar, and there are essentially no controlled studies of any named cultivar's subjective effects in the modern peer-reviewed literature No data.

The common assumption that Kush = sedation is folklore that runs through dispensary shelves, not a pharmacological fact. The indica/sativa split has been repeatedly shown to be a poor predictor of chemistry or effects ^[3] Strong evidence. Individual response varies with dose, tolerance, set, setting, and route of administration far more than with strain name.

Lineage

The lineage of Kush #4 is disputed and largely undocumented Disputed. Depending on the source you ask:

• Some vendors describe it as a selected phenotype from an OG Kush or Bubba Kush seed run.
• Others use 'Kush #4' as a generic in-house label for an unnamed Kush-leaning cut.
• Seed banks occasionally list a 'Kush #4' with proprietary crosses that don't match each other.

None of these claims are backed by breeder records that Weedpedia could verify. The broader Kush family traces to landrace populations from the Hindu Kush mountain region of Afghanistan and Pakistan, brought west in the 1970s and later hybridized extensively in California ^[4][5] Strong evidence. Anything more specific about Kush #4 should be treated as unverified until a breeder publishes documented parentage.

Cultivation basics

Because Kush #4 is not a standardized cultivar, cultivation notes are extrapolated from typical Kush-family behavior rather than measured on this specific plant Weak / limited:

• Structure: Kush lines tend to grow short and stocky with dense internodes, wide leaves, and chunky, resinous flowers.
• Flowering time: Most Kush hybrids finish in 8–9 weeks indoors under 12/12.
• Environment: Kush genetics generally tolerate lower humidity well but are prone to bud rot in dense colas if late-flower RH exceeds ~55%.
• Feeding: Moderate — Kush lines often burn on aggressive nitrogen schedules in late veg.

If you obtain seeds or a clone labeled Kush #4, treat the first run as a phenotype hunt: log flowering time, structure, aroma, and yield yourself. Do not rely on marketing copy.

Marketing vs. reality

The gap between the label 'Kush #4' and what's actually in the jar is wide, and this is true of the cannabis market generally, not just this name:

• Name ≠ genetics. Genetic analyses have repeatedly found that samples sold under the same strain name are often not closely related, and samples with different names are sometimes near-identical ^[1][6] Strong evidence.
• 'Indica' ≠ sedation. The indica/sativa taxonomy has no reliable predictive power for effects at the chemical level ^[3] Strong evidence.
• Numbered phenos are not a quality signal. A '#4' does not mean it beat out phenos 1–3 in some rigorous trial. It usually just means it was the fourth plant the breeder kept notes on.

Buy based on lab-tested chemistry, terpene profile, and — if you can — a source you trust, not on evocative Kush numbering.
