Looking for the best CBG strains to grow? At GTR Seeds, we've spent years developing high-CBG cannabis genetics, from our original groundbreaking CBG varieties to new aromatic, seedless triploid hybrids.
Our breeding program, developed alongside Oregon CBD, pioneered commercially available CBG-dominant cannabis seeds. Today, we offer a diverse selection of feminized CBG strains for premium smokable flower, home cultivation, and commercial biomass production. They are all different - but they all boast shimmering crystal coated flowers and virtually no THC!
Here is a quick guide to our CBG varieties and what makes each one unique.
Classic High-CBG Strains
White CBG
One of our original high-CBG strains, White CBG is known for its impressive resin production, bright white flowers, and exceptionally low THC content. A dependable choice for growers interested in producing high-quality CBG flower or extracts.
Stem Cell CBG
A pioneering CBG variety developed through years of breeding and cannabinoid research. Stem Cell CBG produces large, frosty flowers with minimal aroma, excellent yields, and extremely low THC levels. Particularly well suited for biomass production and extraction.
Sour G CBG
For growers interested in CBG strains with more character, Sour G offers some peppery flavors and a short small statured plant. A great option for exploring unique CBG flower profiles while maintaining the low-THC characteristics of Type IV cannabis.
Auto CBG
Our autoflowering CBG strain is ideal for growers with shorter growing seasons or those seeking a quick harvest. This day-neutral variety completes its life cycle in approximately 11–12 weeks, producing resinous, high-CBG flowers without depending on seasonal changes in daylight.
Triploid CBG Strains: Seedless Genetics
Our newer triploid CBG strains combine high CBG production with reduced fertility, minimizing unwanted seed formation from accidental pollination. These varieties are especially exciting for growers producing premium smokable CBG flower.
Key Lime CBG Seedless
One of our exciting new aromatic CBG strains! Key Lime CBG Seedless produces dense, frosty flowers with pungent lime aromas, impressive bag appeal, and heavy yields. An excellent choice for premium smokable CBG flower production.
Stem Cell CBG Seedless
Building on our original Stem Cell CBG genetics, this triploid variety offers growers another option for high-CBG production with reduced seed formation.
Sourest CBG Seedless
Looking for a loud, flavorful CBG strain? Sourest CBG Seedless delivers an intensely sour terpene profile, sparkling resin, and excellent flower structure. This triploid hybrid brings a new level of aroma to high-CBG cannabis.
White CBG Seedless
A triploid version of our classic White CBG genetics, developed for growers seeking frosty, high-CBG flowers with the added benefits of reduced fertility, bigger flowers, and louder aromas. A favorite for flower producers.
Which CBG Strain Should You Grow?
The best CBG strain depends on your growing goals. For traditional high-CBG production, White CBG and Stem Cell CBG are proven favorites. For quick harvests, Auto CBG is an excellent option. Growers seeking aromatic, premium-quality smokable flower should explore our newer Key Lime and Sourest CBG triploids.
All of our CBG seeds are feminized, and our established CBG genetics have been selectively bred for high cannabinoid content, low THC, and consistent agricultural performance.
