CBG vs. CBD vs. THC vs. THCV: Understanding Cannabis Cannabinoids
One of the most fascinating aspects of cannabis is that it’s much more than just THC. Scientists have identified more than 100 naturally occurring cannabinoids in the cannabis plant, and each one plays a unique role in the plant’s chemistry and how it interacts with the human body.
Whether you’re growing your very first cannabis plant or you’ve been cultivating for years, understanding cannabinoids can help you choose the right genetics, appreciate the diversity of cannabis, and make more informed growing decisions.
At Pura Seed of Oregon, we believe that exceptional cannabis starts with exceptional genetics. Learning about cannabinoids is another important step toward becoming a more knowledgeable cultivator.
Cannabinoids are naturally occurring chemical compounds produced inside the resin glands, or trichomes, of cannabis plants. These tiny crystal-like structures cover mature flowers and sugar leaves and are responsible for producing many of the plant’s most valuable compounds.
While cannabinoids are created by the plant itself, they don’t all perform the same function. Some contribute to the plant’s natural defense system, while others have become the focus of scientific research because of the ways they interact with the human endocannabinoid system.
The four cannabinoids most growers hear about today are THC, CBD, CBG, and THCV. Although they share similar origins, each has its own characteristics and growing appeal.
THC: The Most Recognized Cannabinoid
THC (tetrahydrocannabinol) is the cannabinoid most people associate with cannabis. Fresh cannabis plants actually produce THCA, the acidic precursor to THC. When cannabis is heated through smoking, vaporizing, or cooking, THCA undergoes decarboxylation, converting it into Delta-9 THC.
For growers, THC production is often a major breeding goal. Modern cannabis genetics have been selectively developed over decades to increase resin production and maximize cannabinoid potential. Premium genetics, healthy plants, proper lighting, and an optimized growing environment all contribute to achieving high cannabinoid levels.
CBD: A Popular Non-Intoxicating Cannabinoid
CBD (cannabidiol) has become one of the most widely recognized cannabinoids because it is non-intoxicating and has been extensively studied for its potential wellness applications.
Unlike THC, CBD does not produce the euphoric effects commonly associated with cannabis. Instead, many growers and consumers appreciate CBD-rich cultivars for their balanced cannabinoid profiles and broad appeal.
At Pura Seed of Oregon, cultivars such as Harlequin CBD, Remedy CBD, Studio 54 CBD, and The Kure CBD are excellent choices for growers interested in CBD-rich genetics.
CBG: The “Mother Cannabinoid”
CBG (cannabigerol) is often called the “mother cannabinoid” because nearly every major cannabinoid begins its life as CBGA (cannabigerolic acid). As cannabis plants mature, enzymes naturally convert CBGA into THCA, CBDA, and CBCA. Because most of the CBGA is transformed during flowering, mature cannabis plants typically contain relatively small amounts of CBG unless they have been specifically bred to preserve it.
This important role in cannabinoid development makes CBG one of the most fascinating compounds in cannabis biology. Breeders continue developing new cultivars that retain higher levels of CBG for growers interested in expanding beyond traditional cannabinoid profiles.
THCV: The Rising Star
THCV (tetrahydrocannabivarin) is considered one of cannabis’s most exciting minor cannabinoids. Although its molecular structure resembles THC, THCV behaves differently and is naturally found in much smaller concentrations. THCV is most commonly associated with African landrace sativas and cultivars containing Durban Poison, Haze, Thai, and other equatorial genetics.
At Pura Seed of Oregon, several cultivars feature genetic lineages associated with THCV production. While cannabinoid levels vary by phenotype and can only be confirmed through laboratory testing, these genetics are excellent choices for growers interested in exploring the exciting world of THCV.
Durban Poison is widely regarded as the benchmark for naturally occurring THCV production. This legendary South African landrace sativa is one of the best-known cannabis cultivars associated with elevated THCV levels. Its vigorous growth, resin production, and uplifting characteristics make it a must-have for growers interested in rare cannabinoid genetics.
Girl Scout Cookies (GSC) carries Durban Poison in its lineage, giving it the potential to produce measurable amounts of THCV. This award-winning hybrid combines exceptional resin production, balanced growth, and outstanding flavor with genetics that continue to make it a favorite among breeders and home growers alike.
Candyland inherits its THCV potential through its Durban-influenced ancestry. This colorful, sativa-leaning cultivar is known for vigorous growth, dense resin-coated flowers, and sweet, candy-like aromas. It has become a popular choice for growers looking to explore cultivars with both exceptional flavor and potential minor cannabinoid expression.
Ghost Train Haze combines elite Haze genetics with remarkable potency and abundant trichome production. Its Haze lineage gives select phenotypes the potential to express THCV, making it an exciting option for cultivators seeking rare cannabinoid diversity alongside vigorous plant performance.
SUPER LEMON HAZE:
Super Lemon Haze is beloved for its bright citrus terpene profile and energetic growth. Like many Haze-based cultivars, certain phenotypes may naturally produce THCV, making it an excellent addition for growers interested in exploring unique cannabinoid profiles.
One of the most respected cannabis cultivars ever developed, Jack Herer features classic Haze genetics that may contribute to THCV production in select phenotypes. Its vigorous structure, resin-rich flowers, and legendary reputation continue to make it a favorite among cultivators worldwide.
Headband Haze combines the cerebral qualities of Haze genetics with the popular Headband lineage. The Haze influence increases the likelihood of minor cannabinoid expression, including THCV, while producing aromatic, resinous flowers.
With its tropical sativa heritage, Panama Spice represents another exciting option for growers interested in rare cannabinoid genetics. Landrace and equatorial cannabis varieties have long been associated with naturally occurring THCV, making Panama Spice a unique addition to any cultivation project.
BLUEBERRY THAI:
Blueberry Thai blends flavorful Blueberry genetics with Thai landrace influence. Thai cannabis has occasionally demonstrated the ability to express THCV, giving this cultivar added appeal for growers seeking unique cannabinoid and terpene combinations.
OTHER CULTIVARS WITH POTENTIAL THCV EXPRESSIONS:
Several additional cultivars in the Pura Seed of Oregon collection may also express trace to moderate levels of THCV, particularly in select phenotypes. These include Moby Dick, Sour Diesel, Lemon Sour Diesel, Skunk Orgy Haze, Sour Ghost OG, and Bruce Banner. Although these cultivars are not considered dedicated THCV varieties, their genetic backgrounds may occasionally produce measurable amounts of this fascinating cannabinoid.
As with all cannabinoids, genetics provide the potential, but phenotype selection, cultivation practices, environmental conditions, harvest timing, and laboratory testing ultimately determine the cannabinoid profile of each individual plant. For growers interested in preserving exceptional THCV expressions, selecting and cloning standout phenotypes is often the best path toward consistent future harvests.
Many enthusiasts describe THCV-rich cultivars as offering a clear-headed, energetic, and focused experience, though individual responses vary. Researchers continue studying THCV for its potential roles in metabolism, neurological function, and overall wellness, but much of the research remains ongoing.
Where Do These Cannabinoids Come From?
One of the most interesting facts about cannabis is that these cannabinoids all share a common starting point. Inside the trichomes, the cannabis plant first produces CBGA, often referred to as the “parent cannabinoid.” Specialized enzymes then convert CBGA into THCA, CBDA, or CBCA, depending on the plant’s genetics. This remarkable biochemical process explains why genetics play such a significant role in determining the final cannabinoid profile of every cannabis plant.
Why Genetics Matter
If cannabinoids are the ingredients, genetics are the recipe. Every cannabis seed carries unique genetic instructions that determine the plant’s potential for cannabinoid production, terpene expression, flower structure, growth habits, disease resistance, and countless other characteristics.
Even two plants grown from the same seed pack may display slightly different cannabinoid levels because each seed develops into its own unique phenotype. This is one reason experienced growers often phenotype multiple plants before selecting exceptional individuals for cloning or breeding projects.
Environment Also Plays a Role
While genetics establish the ceiling for cannabinoid production, environmental conditions determine how closely a plant reaches its full potential. Lighting intensity, temperature, humidity, nutrition, watering practices, airflow, harvest timing, drying, and curing all influence cannabinoid preservation and overall flower quality. Healthy plants grown under ideal conditions consistently produce more resin, healthier trichomes, and richer cannabinoid profiles than stressed plants.
Choosing the Right Genetics
Every grower has different goals. Some cultivators focus on maximizing THC production for abundant resin and potency. Others seek balanced CBD cultivars for their unique cannabinoid ratios. Breeders may pursue rare cannabinoids like CBG or THCV to expand genetic diversity and develop tomorrow’s exceptional cultivars. No matter your objective, selecting high-quality seeds provides the strongest foundation for success.
Cannabis Is More Than One Cannabinoid
As cannabis science advances, we’re learning that no single cannabinoid tells the whole story. The remarkable complexity of cannabis comes from the interaction between cannabinoids, terpenes, flavonoids, and hundreds of naturally occurring plant compounds working together. This diversity is one of the reasons cannabis continues to captivate growers, breeders, researchers, and enthusiasts around the world. Understanding cannabinoids allows growers to appreciate not only what they’re cultivating, but why every cultivar is truly unique.
