ABOUT GTR SEEDS

Oregon Cannabis Breeders Since 2015

Oregon GROWN SINCE 2015

Grow the Revolution — Pioneering Cannabis Genetics Through Science

GTR Seeds is an Oregon-based cannabis seed company specializing in feminized F1 hybrid cannabis seeds, triploid genetics, and high-cannabinoid varieties. Founded in 2015 as Oregon CBD by brothers Seth and Eric Crawford, our breeding program has helped pioneer some of the industry's most innovative cannabis genetics, including commercially viable high-CBG seeds, CBDV-rich varieties, and triploid cannabis seeds.

With more than 35 years of combined cannabis breeding experience, Seth and Eric have built a research-driven breeding program focused on producing exceptional genetics for home growers, commercial cultivators, and farmers around the world.

From classic high-CBD hemp varieties to modern THC-rich hybrids and rare cannabinoids like THCV and CBGV, our mission remains the same: develop reliable, high-performing cannabis seeds backed by real science, extensive testing, and generations of breeding expertise.

What Makes GTR Seeds Different?

We're not simply a seed bank reselling other breeders' genetics. We develop our own cannabis varieties through years of selective breeding, scientific research, and extensive agricultural testing.

Our breeding program focuses on the characteristics growers value most:

  • True F1 Hybrid Genetics: Purposefully developed crosses selected for consistency, vigor, and predictable performance.
  • Feminized Cannabis Seeds: Genetics bred to produce female plants, helping growers maximize productive cultivation space.
  • Triploid Cannabis Seeds: Advanced three-chromosome-set hybrids with greatly reduced fertility, helping minimize unwanted seed production.
  • Exceptional Cannabinoid Diversity: Specialized varieties rich in CBD, CBG, CBDV, CBGV, THCV, and THC.
  • High Yields and Premium Flower Quality: Plants selected for productive growth, resin production, desirable aromas, and exceptional flower characteristics.
  • Scientific Research and Testing: Years of cannabinoid analysis, field trials, genomic research, and third-party germination testing.

Every new variety represents years of work to bring growers genetics they can rely on.

Pioneers of High-CBG and Rare Cannabinoid Genetics

GTR Seeds traces its roots to Oregon CBD, one of the pioneering companies in modern cannabinoid-focused cannabis breeding.

Our team helped introduce commercially viable CBG-dominant cannabis seeds, expanding the possibilities of hemp cultivation beyond traditional CBD varieties.

Since then, our breeding programs have expanded to include CBDV, CBGV, THCV, and other specialized cannabinoid profiles that were once extremely difficult to find in commercially available seeds.

Today, growers can explore our extensive selection of CBD seeds, CBG seeds, and other innovative cannabis genetics developed through years of research.

Advancing Triploid Cannabis Seeds

One of our most exciting contributions to cannabis breeding has been the development and commercialization of triploid cannabis seeds.

Traditional cannabis plants are diploid, meaning they contain two sets of chromosomes. Triploid plants contain three sets, which generally results in greatly reduced fertility.

For growers, this can mean substantially less unwanted seed formation when plants are exposed to pollen.

Our triploid breeding program combines this reduced fertility with carefully selected traits such as exceptional resin production, flower quality, cannabinoid content, and agricultural performance.

Science-Driven Cannabis Breeding, Rooted in Oregon

We believe the future of cannabis breeding lies in combining traditional plant breeding expertise with modern genetics, chemistry, and agricultural research.

Our work includes collaborations with researchers and scientific institutions studying cannabis genetics, cannabinoid biosynthesis, and plant performance.

Through these efforts, we continue developing new tools and breeding techniques to better understand the plant and improve the genetics available to growers.

But despite our scientific approach, our priorities remain practical: healthy plants, reliable seeds, excellent flower, and satisfied growers.

Grow the Revolution

From our beginnings as Oregon CBD to our expanding work under GTR Seeds, we've remained committed to advancing cannabis genetics through innovation, transparency, and scientific research.

Whether you're growing a few plants at home or managing thousands of acres, our goal is to provide genetics that deliver exceptional results.

We don't just sell cannabis seeds. We breed them.

Our founders, Seth and Eric Crawford (pictured above), bring over 35 years of combined cannabis breeding experience. We built our reputation in the industry by creating the first consistently stable and reliably feminized F1 hybrid high-CBD, CBG, and CBDV seeds. Our genetics are known worldwide for their remarkable consistency, heavy yields, high cannabinoid content, enticing aromas, and grower-friendly traits.


Over the years, we've always kept an arsenal of heavy-hitting varieties for recreational and open-market growers, but legal restrictions on seed sales have held us back from releasing them. However, times have changed. 

Focusing on the breeding of THC-rich Type I, Type II, THCV, and Triploid cannabis seeds, we're excited to re-emerge as GTR Seeds.
