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?
White CBG – Our Best-Selling CBG Variety
Best for: Premium CBG flower and reliable production
White CBG is one of the original high-CBG varieties developed by Oregon CBD and remains a customer favorite. Known for its dense, heavily resinous flowers, White CBG helped establish CBG as a commercially viable cannabinoid crop.
Its combination of high CBG production, fast flowering, and exceptionally low THC makes it an excellent choice for both commercial growers and smaller cultivators.
Why growers choose White CBG:
-
High CBG concentrations and very low THC.
-
Dense, resin-covered flowers.
-
Fast-finishing genetics.
-
Proven commercial cultivation history.
Our recommendation: An excellent starting point for anyone growing CBG for the first time, particularly those interested in smokable flower.
Stem Cell CBG – Best for Commercial Biomass Production
Best for: Maximum CBG biomass production
Stem Cell CBG was developed with agricultural productivity in mind. This vigorous, high-yielding variety produces substantial flower biomass while maintaining the high CBG-to-THC ratios that make GTR Seeds' CBG genetics distinctive.
For growers focused on cannabinoid extraction, Stem Cell CBG is one of our most dependable options.
Why growers choose Stem Cell CBG:
-
Excellent biomass production potential.
-
High CBG yields.
-
Vigorous plant growth.
-
Very low total THC production.
-
Well suited to commercial field cultivation.
Our recommendation: Our preferred diploid variety for growers prioritizing CBG extraction and large-scale biomass production.
White CBG Seedless – Best for Triploid CBG Flower
Best for: Premium seedless CBG flower
White CBG Seedless brings the proven characteristics of White CBG into a triploid genetic background.
Unlike conventional diploid cannabis plants, triploids contain three sets of chromosomes, resulting in significantly reduced fertility and a much lower likelihood of producing mature seeds following pollen exposure.
This makes White CBG Seedless particularly attractive to growers producing premium smokable CBG flower.
Why growers choose White CBG Seedless:
-
High CBG production potential.
-
Dense, resin-rich flowers.
-
Feminized triploid genetics.
-
Significantly reduced seed formation.
-
Very low THC production.
Our recommendation: A top choice for growers seeking high-quality CBG flower with the added benefits of triploid genetics.
Stem Cell CBG Seedless – Best for Triploid Biomass Production
Best for: High-yielding commercial CBG cultivation
Stem Cell CBG Seedless combines the productivity of our original Stem Cell CBG with advanced triploid breeding.
In GTR Seeds' breeding trials, this variety demonstrated more than 30% greater flower production than its diploid counterpart, making it particularly interesting for commercial growers seeking to maximize cannabinoid yields per acre.
Why growers choose Stem Cell CBG Seedless:
-
Exceptional flower production potential.
-
High CBG concentrations.
-
Reduced fertility and seed formation.
-
Vigorous growth and strong biomass production.
-
Developed for low-THC hemp cultivation.
Our recommendation: One of our most promising options for commercial growers looking to maximize CBG biomass and cannabinoid production.
Auto CBG – Best Autoflower CBG Seeds
Best for: Fast harvests and flexible planting schedules
Auto CBG combines high-CBG genetics with the convenience of autoflowering cannabis.
Unlike traditional photoperiod varieties, autoflowers initiate flowering based on plant age rather than changing daylight hours. This allows growers to cultivate CBG without relying on seasonal day-length changes.
Why growers choose Auto CBG:
-
CBG-dominant cannabinoid production.
-
Feminized autoflower genetics.
-
Flexible cultivation schedules.
-
Suitable for smaller gardens and short-season production.
-
No photoperiod change required to initiate flowering.
Our recommendation: Ideal for growers looking for convenient, fast-finishing CBG genetics.
Sourest CBG Seedless – Best for Distinctive Aromatic Flower
Best for: Exploring aromatic triploid CBG genetics
For growers seeking something different from traditional CBG varieties, Sourest CBG Seedless offers an exciting alternative.
This feminized triploid is part of GTR Seeds' expanding lineup of CBG genetics selected for more than cannabinoid production alone, with an emphasis on distinctive flower characteristics.
Why growers choose Sourest CBG Seedless:
-
CBG-dominant cannabinoid production.
-
Feminized triploid genetics.
-
Reduced fertility.
-
An alternative to classic CBG flower varieties.
Our recommendation: Worth considering for growers seeking variety and distinctive flower characteristics within the CBG category.
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.
