Looking for high CBG seeds? GTR Seeds offers some of the most advanced CBG-dominant cannabis genetics available, including proven commercial hemp varieties, premium smokable flower genetics, autoflowers, and innovative triploid CBG seeds.
CBG (cannabigerol) is a naturally occurring, non-intoxicating cannabinoid that has attracted growing interest from researchers, hemp farmers, and cannabinoid processors. Often called the "mother of all cannabinoids," its acidic precursor, CBGA, serves as the starting point for the biosynthesis of major cannabinoids including THC and CBD.
While most conventional cannabis plants contain relatively little CBG at maturity, specialized breeding has made it possible to produce CBG-dominant plants with exceptionally high cannabinoid concentrations and very low THC levels.
At GTR Seeds, breeders Seth and Eric Crawford helped pioneer commercially viable high-CBG cannabis genetics, developing varieties specifically for CBG production rather than relying on plants harvested before maturity.
Today, our CBG seed catalog includes a wide range of feminized varieties designed for different growing environments and production goals.
Which CBG Seeds Are Right for You?
GTR Seeds offers a diverse selection of feminized CBG seeds, from our original high-CBG varieties to innovative triploid and autoflower genetics. Whether you're growing premium smokable flower or maximizing commercial biomass production, these six varieties offer something for nearly every grower.
White CBG — Our Best-Selling CBG Variety
Best for: Premium CBG flower and reliable production
One of the original high-CBG varieties developed by Oregon CBD, White CBG is celebrated for its incredibly frosty, resin-covered flowers, high CBG concentrations, and exceptionally low THC production. Its relatively mild aromatic character, compact bushy structure, and early September maturity make it an excellent choice for growers of all sizes.
Our recommendation: A fantastic introduction to CBG cultivation, particularly for growers seeking beautiful, high-quality smokable flower.
Stem Cell CBG — Best for Commercial Biomass Production
Best for: Maximum CBG yields and extraction
Stem Cell CBG is a vigorous, highly productive variety known for its massive flowers and exceptional cannabinoid yields. Its mild, understated aroma and flavor make it particularly well suited for extraction rather than terpene-focused smokable flower. A dependable choice for commercial growers seeking high CBG production with minimal THC.
Our recommendation: Our preferred diploid CBG variety for commercial biomass production, tinctures, and extracts.
White CBG Seedless — Best for Premium Triploid CBG Flower
Best for: Aromatic, resin-rich CBG flower
White CBG Seedless takes our classic White CBG genetics to another level, producing exceptionally frosty flowers with noticeably stronger aromas than the original. This feminized triploid combines dense, easy-to-trim buds with reduced fertility, impressive yields, and outstanding flower quality. Its compact, bushy structure makes it particularly attractive for indoor cultivation.
Our recommendation: One of our favorite CBG varieties for premium smokable flower and solventless extraction.
Stem Cell CBG Seedless — Best for Triploid Biomass Production
Best for: Maximum CBG production per acre
Stem Cell CBG Seedless combines the extraordinary productivity of our original Stem Cell genetics with triploid breeding technology. In GTR Seeds' trials, this variety produced over 30% more flower than its diploid counterpart. Its mild aromatic profile, enormous flowers, and reduced fertility make it particularly appealing for large-scale CBG extraction.
Our recommendation: A top choice for commercial growers looking to maximize CBG biomass and cannabinoid yields.
Auto CBG — Best Autoflower CBG Seeds
Best for: Fast harvests and flexible planting schedules
Auto CBG combines high-CBG production with the convenience of autoflowering genetics. Rather than relying on changing daylight hours to initiate flowering, these plants flower according to age, making them ideal for flexible planting schedules and short growing seasons. An excellent choice for growers prioritizing convenience and cannabinoid production over elaborate terpene profiles.
Our recommendation: Ideal for home growers, short-season cultivation, and anyone seeking fast, easy-to-manage CBG genetics.
Sourest CBG Seedless — Best for Distinctive Aromatic Flower
Best for: Unique CBG flower and triploid genetics
Sourest CBG Seedless offers an exciting alternative to traditional CBG varieties, with a focus on aromatic flower quality rather than cannabinoid production alone. This feminized triploid brings sour-forward character to the CBG category while offering reduced fertility and desirable flower characteristics.
Our recommendation: An excellent option for growers seeking distinctive, sour terpene-focused CBG flower with the advantages of triploid breeding.

What Does Science Say About CBG?
While CBD has received much of the scientific attention surrounding non-intoxicating cannabinoids, research into CBG has expanded considerably.
Scientists are investigating its interactions with cannabinoid receptors, its potential effects on inflammation, and its influence on several biological pathways.
Here are three peer-reviewed studies worth exploring.
1. CBG, Anxiety, Stress, and Mood (2024)
A randomized, double-blind, placebo-controlled study published in Scientific Reports investigated the effects of CBG in 34 healthy adults.
Researchers found that a single 20 mg dose of CBG was associated with reductions in self-reported anxiety and stress compared with placebo, without evidence of intoxication or motor impairment.
Although promising, the results come from a small, short-term study and require confirmation in larger clinical trials.

2. CBG and Inflammatory Bowel Disease (2013)
A study published in Biochemical Pharmacology examined the effects of CBG in an experimental mouse model of colitis.
Researchers observed reductions in several markers of intestinal inflammation and oxidative stress.
These findings helped establish interest in CBG's potential anti-inflammatory properties, although the study was conducted in animals rather than human patients.
3. The Pharmacological Case for Cannabigerol (2021)
This scientific review, published in the Journal of Pharmacology and Experimental Therapeutics, examines the unique pharmacology of CBG and its interactions with several receptor systems.
The authors discuss emerging research into neurological disorders, inflammation, and antibacterial activity, while emphasizing that much of the evidence remains preclinical.

Important: Although early research is encouraging, CBG has not been established as an effective treatment for anxiety, inflammatory bowel disease, or other medical conditions. Studies involving purified CBG do not necessarily predict the effects of consuming CBG-rich cannabis flower.
Why Choose GTR Seeds for CBG Genetics?
GTR Seeds and Oregon CBD were among the earliest breeders to develop high-CBG cannabis varieties suitable for commercial cultivation.
Producing reliable CBG-dominant genetics requires more than simply selecting plants with elevated CBG concentrations. Our breeding program focuses on maintaining high cannabinoid production, vigorous growth, agricultural consistency, and exceptionally low THC levels.
Our CBG varieties are particularly noteworthy for their favorable CBG-to-THC ratios, with many producing total THC concentrations below 0.2% at maturity.
Today, we continue to advance CBG breeding through the development of triploid genetics, improved flower production, and new aromatic varieties.
Whether you're growing CBG for extraction, premium flower, or simply exploring this fascinating cannabinoid, GTR Seeds offers genetics developed through years of research and selective breeding.
