Sour #29
An undocumented strain name with no verifiable breeder or published chemistry data.
Growing, buying or possessing cannabis and seeds is legal only in some places. Check the law where you live before acting on this information.
Sour #29 appears on some dispensary menus and consumer strain databases, but has no documented breeder, seed bank release, or published lab data. The '#29' suggests a phenotype selection (a common small-breeder naming practice), but without a named originator or verifiable lineage, the name tells you almost nothing about what's actually in the jar. Buy based on grower reputation, batch testing, and how it smells—not the strain name.
What we could verify
Sour #29 appears as a strain name on consumer cannabis databases and occasional dispensary menus. We could not locate a breeder of record, a seed bank or nursery release with documented provenance, a published certificate of analysis (COA) for any batch, or any peer-reviewed or established journalism coverage that names this cultivar No data.
Unlike well-documented strains such as Sour Diesel or Sour #13, Sour #29 has no verifiable origin story, no named originator, and no published chemistry data tied to it.
What the name suggests—and why that is not evidence
The '#29' notation is a common naming convention among cannabis breeders, particularly in phenotype hunts—selecting the twenty-ninth plant from a batch of seeds or cuttings Weak / limited. Established breeders like Cookies have used numbered cut selections (e.g., 'Girl Scout Cookies #1') with publicly verifiable lineage and documented releases.
For Sour #29, the '#' format suggests someone may have done a pheno hunt, but without a named breeder, parent cultivars, or documented selection criteria, this remains speculation No data. The word 'Sour' links the name to a family of strains—Sour Diesel, Sour Bubble, East Coast Sour Diesel—but similarity in name does not establish genetic relationship. Many breeders apply descriptive terms ('sour,' 'diesel,' 'haze') to unrelated crosses Weak / limited.
What to check if you see it for sale
If a dispensary or vendor offers Sour #29, ask for:
- A Certificate of Analysis (COA) from a third-party testing lab. The COA will show you actual cannabinoid and terpene content for that specific batch, which is far more informative than the strain name [1] Strong evidence.
- Breeder or grower name. A reputable vendor should tell you who cultivated it. If they cannot or will not, that is a red flag.
- Harvest date. Cannabis degrades over time; fresher flower is typically better. Avoid jars with no date or a date more than 6–8 months old.
- Visual inspection and smell. Buy based on observable quality—no mold, no visible mites, no musty or chemical odour—and how it smells to you, not marketing copy.
Cannabinoid and terpene content varies more between grows of the same strain than between many different strains [1][2] Strong evidence. Two jars labeled Sour #29 from different growers are likely to be chemically quite different, so the batch COA matters far more than the name on the label.
Similar documented strains
If you are looking for strains with published breeder records and more transparent lineage:
- Sour Diesel – the foundational sour cultivar, with well-documented (though contested) lineage and widespread seed-bank availability [3].
- Sour #13 – another numbered sour selection, more widely documented in seed banks and grow communities.
- Sour #97 – a third numbered variant with better paper trail than Sour #29.
- Bull Diesel – a diesel-family hybrid with clearer breeder attribution.
Each of these strains has been tested and reviewed by multiple independent labs and growers, so you can find actual chemistry and grow data. Weak / limited
Frequently asked questions
Is Sour #29 an indica, sativa, or hybrid?
Without a documented lineage, we cannot say. Consumer reports describe it as 'sativa-leaning,' but the indica/sativa/hybrid framework does not reliably predict effects; chemistry (cannabinoids and terpenes) and user factors (dose, tolerance, setting) matter far more [2][4] Strong evidence. See The Indica/Sativa Myth for more detail.
What is the THC level?
Not documented. Any specific THC percentage you see on a dispensary label without a COA is a guess. Modern U.S. flower typically ranges 15–25% THC [3] Strong evidence, so a specific Sour #29 batch might fall anywhere in that range depending on the grower. Always request the lab test.
How long does it take to flower?
Not documented for this cultivar. If it shares Sour Diesel genetics (unconfirmed), you might expect 8–10 weeks, but that is speculation without a verified breeder statement or documented grow reports No data.
Who bred Sour #29?
Unknown. No breeder has publicly claimed or documented it. If you have information about the originator or a copy of the strain's lineage documentation, you can flag an error with Weedpedia to help fill this gap.
