Haze #27
A numbered Haze selection with disputed lineage and no official documentation.
Growing, buying or possessing cannabis and seeds is legal only in some places. Check the law where you live before acting on this information.
Haze #27 is talked about in growing forums but has never been officially released by a major seed bank or documented in peer-reviewed literature. No breeder, lab tests or stable genetic record exists to verify it as a single cultivar. What you find labeled 'Haze #27' online may be from different growers claiming the same name. If you see it for sale, ask for a [Certificate of Analysis (COA)](certificate-of-analysis-coa) and breeder provenance before buying.
What We Could Verify
Haze #27 appears in cannabis growing forums, seed vendor listings, and user discussions online, primarily in European growing communities. The name follows the Haze family numbering convention (e.g., Haze #47, Haze #99), suggesting it may be a numbered selection within a larger breeding line. However, no peer-reviewed scientific paper, government regulatory record, official seed bank product page, or verifiable breeder documentation exists for 'Haze #27' as a distinct, stable cultivar No data.
Unlike other numbered Haze strains such as Haze #47 and Haze #99, which have traceable seed bank histories, Haze #27 has no single authoritative source or company claim. The broader Haze family has well-documented origins; numbered selections within that family often do not Anecdote.
Why the Name Alone Is Not Evidence
Cannabis strain names are not regulated or standardized. A name like 'Haze #27' can be used by multiple growers to describe different plants, and there is no central registry to verify that a specific genetic background corresponds to that label Weak / limited.[1]
In unregulated or legacy seed markets, the same strain name may refer to:
- Different phenotypes from the same breeding line
- Seeds from separate breeders using the same marketing name
- Crosses that have diverged over many generations of informal breeding
- Mislabeled or incorrectly named plants
The lack of an official Haze #27 seed bank release means no company has fixed, documented, and distributed a stable genetic line under that name. Every 'Haze #27' in circulation may have a different genetic history.
How to Check If You See It for Sale
If a vendor offers seeds or plants labeled 'Haze #27', ask for the following before purchasing:
1. Breeder or Source Who created this line? Ask for the breeder's name, website, or documented history. Legitimate breeders maintain records of their strains and can describe their crossing work.
2. Certificate of Analysis (COA) For any cannabis product (flower, seeds, clones), a Certificate of Analysis (COA) from an accredited lab confirms cannabinoid and terpene content for that specific batch. No COA means no way to verify what you are buying Weak / limited.[2]
3. Batch or Generation Documentation Ask which generation of breeding this seed represents (e.g., F1, F2, stabilized line). Undocumented seeds are likely unstable or misidentified.
4. Lineage Transparency Demand specificity: Which parent strains, from which sources? 'Old Dutch genetics' is marketing language, not evidence. Named parents with breeder histories are stronger claims.
If a vendor cannot or will not provide these details, the product is not reliably documented as Haze #27.
Similar Documented Strains
If you are looking for verified long-flowering, tall-growing Haze cultivars with recorded breeding history and seed bank release, consider:
- Haze #47 – A documented Haze selection with a verifiable seed bank history
- Haze #99 – Another numbered Haze with established lineage documentation
- Super Silver Haze – A widely available, officially released Haze hybrid with consistent commercial availability
- Amnesia Haze – A modern Haze cross with extensive lab testing data and breeder documentation
All of these strains have been officially released by seed banks, tested by independent labs, and grown widely enough to establish a consistent phenotype. They offer the same long-flowering, sativa-dominant character as Haze #27 is claimed to have, with the added benefit of documented authenticity.
Frequently Asked Questions
Is Haze #27 sativa or indica? Haze #27 is described online as sativa-dominant, but without official documentation or stable genetics, this claim cannot be independently verified. The broader Haze family is sativa-heavy, which supports the likelihood. However, remember that the indica/sativa myth oversimplifies cannabis effects—strain name does not reliably predict how you will feel.
What THC level does Haze #27 have? No lab-verified data exists. Online sources claim 18–22% THC, but these are unattributed reports from unverified samples. Always request a Certificate of Analysis (COA) from the specific batch you buy to know the actual cannabinoid content.
How long does it flower? Growing forums report 10–12 weeks, but this is unverified for Haze #27 specifically. Haze-family strains generally flower longer than modern hybrids. If you are buying seeds or clones, ask the vendor for the documented flowering time from their specific line.
Who bred Haze #27? Unknown. The most common claim is that it emerged from Dutch breeding circles in the 1990s–2000s, but no breeder has formally documented or claimed authorship. If you own seeds or plants labeled Haze #27, contact the seller for the original breeder's information.
Help Us Verify This Strain
If you have documentary evidence that Haze #27 is a real, documented cultivar—including breeder records, seed bank product pages, or accredited lab reports—please share it. Evidence we need:
- A seed bank or breeder website that currently or historically offered 'Haze #27' with documented parentage
- Lab certificates of analysis showing cannabinoid and terpene data labeled 'Haze #27'
- Published growing records or cultivar descriptions from established cannabis breeders
- Regulatory documentation or seed certification linking the name to a stable genetic line
