Cannabis strain names can tell you something about a product’s identity, reported genetic background or marketed characteristics, but they do not always provide a complete picture of its chemical composition. Names such as OG Kush, Northern Lights and Blue Dream are widely recognised in cannabis culture, while labels such as indica, sativa and hybrid are commonly used to describe broad categories of cannabis.
Understanding these terms makes it easier to interpret product descriptions, compare different varieties and distinguish traditional naming conventions from information supported by laboratory testing.
This guide explains what a cannabis strain is, how strain names are created, what indica, sativa and hybrid labels mean, and why genetics, cannabinoids and terpenes are important when comparing cannabis flower.
1. What Is a Cannabis Strain?
A cannabis strain is a commonly used term for a named type or variety of cannabis. Strain names are used by growers, breeders, retailers and consumers to distinguish plants or products that may have different genetic backgrounds, aromas, flavours and chemical profiles.
For example, two cannabis products may have different strain names because they are associated with different breeding histories or have been selected for different characteristics. However, a name alone does not confirm that every product sold under that name has identical genetics or composition.
Cannabis strain names can refer to several kinds of information:
- Genetic background: The reported parent varieties or breeding lineage.
- Aroma and flavour: Descriptions associated with a variety, such as citrus, earth, pine or sweet fruit.
- Plant characteristics: Features such as growth structure, flowering traits and flower appearance.
- Cannabinoid profile: The amounts of compounds such as THC and CBD present in a particular sample.
- Cultivar identity: The named cultivated variety to which the plant is said to belong.
These characteristics are not necessarily consistent across every product carrying the same name. Genetics, cultivation conditions, harvesting, drying, curing and storage can all influence the final flower.

Why do cannabis strains have different names?
Names help distinguish varieties and communicate information about their reported lineage or recognisable characteristics. Some names reflect a breeder’s chosen branding, while others refer to a parent variety, a place, a flavour association or a feature that became popular among consumers.
However, cannabis naming has no single universal system. The same name may be used inconsistently by different producers, and similar names do not necessarily indicate identical genetics.
For this reason, strain names are useful identifiers, but they should not be treated as complete scientific descriptions.
2. What Do Indica, Sativa and Hybrid Mean?
Indica, sativa and hybrid are three labels frequently used in cannabis descriptions. They have historical and botanical associations, but modern commercial cannabis terminology often uses them as broad categories rather than precise descriptions of genetic ancestry or chemical composition.
Indica
Indica is a label traditionally associated with certain cannabis plants that tend to have relatively compact growth patterns, broader leaflets and other characteristic botanical features.
In retail descriptions, indica is also commonly used as a category for named cannabis varieties. Some product descriptions associate indica-labelled varieties with particular effects, but these claims should not be assumed to apply consistently to every product.
The label alone does not establish a flower’s THC concentration, CBD content, terpene profile or likely individual response.
Sativa
Sativa is a term with a long history in cannabis classification. Traditionally, it has been associated with plants displaying features such as taller growth and narrower leaflets, although plant characteristics vary and do not always fit a simple division.
In modern product descriptions, sativa is often used as a category to distinguish certain cannabis varieties from those labelled indica. Retail descriptions may also attach general effect expectations to the term.
Those expectations are not reliable guarantees. A sativa label does not independently reveal the product’s cannabinoid composition or establish how a particular person will respond.
Hybrid
Hybrid generally refers to cannabis described as having ancestry from different varieties or genetic lines. Many modern commercial cannabis varieties have complex breeding histories, so hybrid ancestry is common.
Retailers sometimes use additional labels such as indica-dominant hybrid or sativa-dominant hybrid. These descriptions suggest how a product is categorised within a particular naming system, but the terms may not follow a consistent scientific measurement.
A hybrid label does not necessarily mean that a product combines the effects of indica and sativa in a predictable way.
How should you interpret the three labels?
The most useful approach is to regard indica, sativa and hybrid as starting points for understanding how a cannabis variety is described, rather than as definitive indicators of its chemistry or effects.

3. What Is the Difference Between a Strain and a Cultivar?
The terms strain and cultivar are sometimes used interchangeably in cannabis discussions, but they have different meanings.
A cultivar is a cultivated plant variety selected and maintained for particular characteristics. The word combines the concepts of cultivation and variety. In botanical and horticultural contexts, it is a more specific term for a named cultivated variety.
A strain is a broader, commonly used term in cannabis culture and commerce. It may refer to a named variety, a reported genetic line or a product identity, depending on the context.
The distinction matters because a commercial strain name does not always establish a formally documented cultivar identity.
| Term | General meaning | What it tells you |
|---|---|---|
| Strain | Common cannabis term for a named type or line | A product or variety’s commonly used identity |
| Cultivar | A cultivated plant variety selected for particular characteristics | A more specific horticultural concept |
| Phenotype | Observable characteristics resulting from genetics and environmental influences | How a particular plant expresses its traits |
| Genotype | The genetic constitution of an organism | Information about its genetic makeup, not necessarily its full observable characteristics |
What is a cannabis phenotype?
A phenotype refers to the observable characteristics of a plant. These can include its growth pattern, flower structure, pigmentation and other features influenced by genetics and growing conditions.
Plants with related genetic backgrounds can display different characteristics under different environmental conditions. Conversely, plants that look similar are not necessarily genetically identical.
This helps explain why two products sold under the same strain name may differ in appearance, aroma or measured cannabinoid levels.
Why does the terminology matter?
The term used in a product description may indicate whether the seller is referring to a named commercial variety, a documented cultivated variety or a particular plant expression.
However, neither the word strain nor the word cultivar automatically verifies genetic authenticity. Reliable identification requires supporting information rather than a name alone.
4. How Do Cannabis Strains Get Their Names?
Cannabis strain names can originate from breeders, growers, established varieties, branding decisions or characteristics associated with a particular plant. Naming conventions have developed over time, and there is no single naming authority that ensures every commercial name is used consistently.
Several common naming approaches appear throughout cannabis culture.
Names based on genetic lineage
Some names preserve information about a variety’s reported parentage. A named cultivar may be associated with two parent varieties, and its name may reflect one or both of them.
For example, a breeder might create a new name by combining parts of two parent names. This can make a variety easier to recognise, but the name alone does not independently verify its ancestry.
Names inspired by aroma or flavour
Some strain names refer to reported sensory characteristics, including citrus, berry, dessert-like or earthy aromas.
These names may reflect how a particular variety is marketed or described. They do not prove that the flower contains a particular flavouring ingredient or that every batch will have the same aroma.
Actual aroma can vary according to the flower’s terpene profile, other volatile compounds, growing conditions and post-harvest handling.
Names based on appearance
Other names refer to the reported appearance of a plant or its flowers. Descriptions may highlight colour, flower structure or visual features associated with a particular variety.
Appearance alone, however, is not a dependable way to establish strain identity or chemical composition.
Names created for branding
Some cannabis names are developed primarily to establish a recognisable product identity. A memorable name can help distinguish a product in a crowded market, but commercial branding should not be confused with scientific classification.
Two sellers using similar names may not be offering genetically identical material. Likewise, the same variety may be sold under different names in different markets.
Can two different strains have the same name?
Yes. Inconsistent naming, informal propagation and differences between commercial markets can result in overlapping or ambiguous names.
A name may be used without a clearly documented breeding history, or a product may be described using a familiar name despite differences in its underlying genetics.
When accurate identification matters, useful supporting information includes breeder records, traceable batch details and credible laboratory documentation.
5. Can Strain Names Predict Cannabis Effects?
Cannabis strain names and labels such as indica, sativa and hybrid are often used to suggest what a product may feel like. However, they are not reliable standalone predictors of an individual’s response.
The effects associated with cannabis can depend on several factors, including:
- The product’s THC and CBD concentrations.
- Other cannabinoids and naturally occurring compounds.
- The amount consumed and route of administration.
- Individual sensitivity, previous exposure and biological differences.
- The product’s consistency, formulation and actual chemical composition.
Descriptions such as relaxing, uplifting or energising may reflect consumer reports or marketing conventions. They should not be interpreted as guaranteed outcomes or medical claims.
Why the label may not tell the whole story
Commercial indica and sativa labels do not consistently correspond to clearly separated genetic groups. Modern breeding has created complex genetic relationships, and products within the same retail category can have different chemical profiles.
As a result, two products labelled indica may differ considerably in THC concentration and terpene composition. The same is true of products labelled sativa or hybrid.
A strain name can provide context, but it should not replace verified product information or an understanding of the uncertainty surrounding individual responses.
Does a higher THC percentage guarantee a stronger experience?
No single percentage can predict every aspect of a person’s experience. THC concentration is relevant when evaluating a product’s composition, but the amount consumed, individual sensitivity and other factors also matter.
A laboratory result is a measurement of a sample, not a guarantee of a specific experience. Products should not be compared on strain names or THC percentages alone.
6. Why Genetics, Cannabinoids and Terpenes Matter
Understanding cannabis varieties involves looking beyond their names. Genetic background, cannabinoid composition and terpene profiles provide different kinds of information, and each has its own limitations.
Genetics and breeding history
Genetics can help explain relationships between varieties and the inheritance of certain plant traits. Documented parentage and credible breeder information may provide a stronger basis for understanding a variety than a retail name alone.
However, a claimed lineage is only as reliable as the information supporting it. A name that suggests particular parent varieties does not establish genetic authenticity without suitable evidence.
Cannabinoids
Cannabinoids are chemical compounds associated with cannabis. THC and CBD are two of the best-known examples.
THC is primarily associated with the intoxicating effects of cannabis, while CBD is not intoxicating in the same way. Their amounts can vary between varieties and individual batches.
Other cannabinoids may also be present, but their concentrations and the evidence concerning their effects vary.
A strain name does not establish the amount of any cannabinoid. Where composition matters, batch-specific laboratory results are more informative than a product’s name or a general strain description.
Terpenes
Terpenes are a broad group of naturally occurring compounds found in many plants, including cannabis. They contribute to characteristic aromas and are commonly discussed when describing cannabis flower.
Examples include:
- Myrcene: Found in various plants and often associated with earthy or musky aroma descriptions.
- Limonene: Associated with citrus-like aromatic notes.
- Pinene: Commonly associated with pine-like aromas.
- Caryophyllene: Found in several plants and often described as spicy or peppery.
These descriptions are general sensory associations, not guarantees that a particular flower will smell a certain way. A terpene’s presence does not independently establish a predictable effect, and research into how individual compounds contribute to the overall experience remains an evolving area.
Why all three factors should be considered together
Genetics may help explain a plant’s background, cannabinoid testing describes measured chemical concentrations, and terpene analysis can provide information about selected aromatic compounds.
These forms of information answer different questions. None alone provides a complete description of a product, and laboratory testing does not establish that cannabis is safe to consume. For more details browse Cannabis Terpenes Explained
7. How to Compare Cannabis Strains Using Lab Reports
Laboratory reports can provide more specific information about a tested cannabis sample than a strain name or general product description. These reports are often called certificates of analysis, or COAs.
A COA should be interpreted according to the sample tested, the laboratory methods used and the compounds or contaminants included in the analysis.
Check the product and batch details
Start by checking whether the report identifies the relevant product, sample or batch. A report for a different batch may not accurately represent the material being described.
Where available, compare the product identifier, batch number, sampling date and report date. Traceability helps establish whether the report relates to the product in question.
Review cannabinoid results
A cannabinoid panel may report THC, CBD and other measured cannabinoids. Check the units and the basis of the reported values, because results may be expressed in different ways.
Do not assume that every report measures the same compounds or uses identical testing methods.
Understand terpene results
Some laboratories provide terpene analysis, while others do not. When a terpene panel is available, it can help describe the sample’s measured aromatic compounds.
The presence of a terpene does not prove a specific effect, and results should not be treated as a complete explanation of a product’s sensory characteristics.
Check what contaminants were tested
Depending on the laboratory and applicable requirements, a report may include tests for pesticides, heavy metals, microbial contamination, residual solvents or other substances.
Check which tests were actually performed and whether the results meet the relevant criteria. A report that tests only cannabinoid concentrations cannot establish that every possible contaminant is absent.
Understand the limitations of a COA
A COA is not a universal safety certificate. Its value depends on the laboratory’s competence, the sample’s representativeness, the methods used and the scope of the testing.
For a more detailed explanation of laboratory reports and how to interpret them, read our THC flower COA guide.
A practical comparison checklist
When reviewing information about two named cannabis varieties, compare the following:
- Identity: Is there credible information about the named variety and its reported lineage?
- Batch: Does the documentation correspond to the actual sample or product?
- Cannabinoids: Are THC, CBD and other reported compounds measured on a comparable basis?
- Terpenes: Is a terpene profile available, and does it cover the same compounds in both samples?
- Testing scope: Which contaminants were tested, and what do the results actually establish?
- Limitations: Are claims about effects or quality supported by evidence, or are they based mainly on the name and marketing description?
This approach provides a more informative comparison than assuming that two products with similar names, or the same indica or sativa label, are chemically identical.
8. Frequently Asked Questions About Cannabis Strain Names
What is a cannabis strain?
A cannabis strain is a commonly used term for a named cannabis variety or genetic line. The name may refer to reported ancestry, a recognised commercial identity or characteristics associated with the plant. However, a strain name does not automatically verify genetics or confirm the product’s chemical composition.
What does cannabis cultivar mean?
A cannabis cultivar is a cultivated plant variety selected and maintained for particular characteristics. The term is more specific in botanical usage than the broadly used word strain. In commercial cannabis descriptions, the two terms may overlap, but a name alone does not establish formal cultivar identity.
What is the difference between indica, sativa and hybrid?
Indica and sativa have historical botanical associations and are widely used as retail categories. Hybrid generally describes a variety with mixed ancestry. In modern commercial markets, these labels are not consistent enough to establish a product’s exact genetics, cannabinoid profile or likely effects.
How do cannabis strains get their names?
Names may be inspired by parent varieties, reported aroma or flavour, appearance, breeding history or branding decisions. Since there is no universal naming system for every commercial product, the same name may be used inconsistently.
Can cannabis strain names tell you how much THC a product contains?
No. A name does not reliably establish THC concentration. A relevant laboratory report can provide measured results for the tested sample, although the report’s scope and relationship to the product should always be checked.
Are cannabis strain names scientifically reliable?
They can be useful identifiers, particularly where a variety has documented breeding records. However, names are not always standardised or independently verified. Genetics, traceability and laboratory analysis provide different forms of evidence that can help clarify what a product actually is.
Are terpenes responsible for the effects of each strain?
Terpenes contribute to aroma and are being studied for their possible biological roles, but their presence does not establish a predictable effect. Cannabis experiences involve multiple factors, and claims that an individual terpene or strain label guarantees a particular response should be treated cautiously.
What is the best way to compare two cannabis strains?
Start with the identity and reported lineage of each variety, then compare reliable product information and relevant laboratory results. Cannabinoid measurements, available terpene data and testing scope provide more specific information than names alone, but they do not guarantee a particular experience or establish that a product is risk-free.
Cannabis Strain Names Final Thoughts
Cannabis strain names help people distinguish varieties and communicate information about reported genetics, aroma, flavour and commercial identity. However, names are not a universal scientific classification system, and labels such as indica, sativa and hybrid should not be treated as definitive predictions of chemical composition or effects.
Understanding the distinction between strains and cultivars, reviewing credible genetic information and checking relevant laboratory reports can provide a more accurate picture of a cannabis product.
Ultimately, a strain name is a starting point for identification, not a substitute for evidence about the plant or product itself.
