Founded in 2015, we are Oregon's oldest federally-legal cannabis research and development company, operating in compliance with the 2018 Farm Bill. This allows our company to permanently work with unlimited plant numbers and fully explore the diversity and malleability contained in the cannabis genus. Our primary product is scientific knowledge, but we strive to put our best findings into growers’ hands in the form of world-class, non-GMO, and award winning cannabis seeds for production purposes and improve our work every year. 

In 2021 we released the first commercial triploid cannabis seeds. Bigger yields, louder aromas, Certified Organic, Non-GMO, and high in THC, THCV, CBD, CBG, and other minor cannabinoids.

Bermuda Triangle Seedless

Double Durban THCV

White CBG Seedless

GTR Seeds / Oregon CBD

Cannabis

Durban V1 x Auto Durban THCV
Type I, Varin Rich

The development of this variety is a textbook case of classical breeding applied to cannabis in order to achieve a particular outcome--and holy shit ladies and gentlemen:  mission accomplished.  This is the variety many in the cannabis world have been waiting generations for:  a Durban Poison flavor and experience every single time, but married to a consistently high THCV cannabinoid fraction (50%).  Durban Poison was long rumored to carry a high proportion of THCV, but we never found that to be the case with commercially available germplasm. 

Instead, we took our inbred, in-house Durban and converted it to THCV production through old fashioned line breeding and selection.  When combined with the Auto Durban THCV line, growers essentially get the production consistency of an inbred Durban variety combined with the hybrid vigor of an F1--and the early flowering characteristics that our hybrids are known for.  This is the crown jewel of THCV production for trimmed flowers.


Feminized THCV Seeds
Ratio: 1:1 THCV to THC
Flowering Time: 8-9 Weeks
Finishing: Mid to Late September Outdoors


Urkle Kush V x Auto Durban THCV

 Type 1, Varin Rich

Another case of classical breeding, this time bringing one of the most interesting flavor combinations we’ve experienced to market and doing so with approximately 50% of the total cannabinoid fraction as THCV--truly a marvel to behold.  Our selected production mother “Urkle Kush” (Purple Urkle x Triangle Kush), known for its epic productivity, cannabinoid content, and aroma in our adult use greenhouses, was brought into the varin breeding program in 2020. 

Three years later, we have developed an incredibly aromatic and visually spectacular inbred production mother with a THCV dominant cannabinoid fraction; when combined with the Auto Durban THCV line, growers will experience the most complex and loud olfactory expressions available in THCV rich flowers.

Garlic Berry THCV

Tropical flavor paradise meets compliant trimmed flowers in this triploid hybrid. By pairing our Suver Haze production mother with a type I, varin-rich variety, then inbreeding and selecting over several generations to lock-in our targeted traits of interest, we were able to create the highest, fully legal CBD content variety available to humans. Rich aromas of mango, guava, and coconut merge with the berry notes from VERB to create what may become the most relaxing plant on the planet. Extremely limited release in 2021.

40%-55% of the total cannabinoid fraction is high value CBDV
Fully compliant at day of harvest for total THC
Tantalizing and exotic tropical fruit aromas

Forbidden V Seedless

*1st Place 2020 Oregon Growers Cup*

We took one of the superstars of cannabinoid production ("The White," an elite THC variety) and converted it to a pure CBG chemotype. Plants grow into stout bushes with large frosty flowers. Beautiful bag appeal makes it an excellent choice for cut flower, with some producers even running it in light deprivation greenhouses. This varieties dense flower production is better suited for drier climates.

•   Fast growing with potential for large quantities of A grade flower
•   A varied but solid terpene profile
•   Our highest testing CBG flower
•   Huge colas better suited for drier climates

White CBG

*1st Place 2020 High Times Hemp Cup*

(DC Haze “CC” x ERB)
Visitors to our field trials gravitated towards this plant in particular and reminisced about the truly special flavors that emanate from imported Hawaiian flowers (beta-carypholene and humulene are key secondary and tertiary terpenes). Hawaiian Haze brings farmers a unique opportunity to grow equatorially-inspired, long season flavors at any latitude and to do so with large yielding, modern hybrid flower structure.
•	Excellent field ready strain for biomass as well as fresh cut flowers
•	Unique terpene profile that oozes tropical funk
•	Large medium density buds

Hawaiian Haze

*1st Place 2020 Cultivation Classic*
*1st Place 2019 Cultivation Classic*

(Suver #8 x ERB)
Suver Haze is a very special variety that performed well from Oregon to South Carolina in her inaugural year. Our first R&D facility was located along Suver Road, in the former epicenter of Oregon grass seed development. The area has a rich farming and social history and we offer this as our contribution to the legend. This strain continues to impress us with her structure, strength, stank, and cannabinoid content. 

•	Excels in moist climates and exhibits strong resistance to botrytis
•	Our highest ever recorded CBD content producer at 25%
•	Exotic sour apple flavor created by farnsene and beta-caryophyllene terpene content

Suver Haze

*2nd Place 2019 Cultivation Classic*

(ACDC x ERB)
ACDC is the famous Cannatonic phenotype that helped revolutionize west coast CBD production. As a clone, she is not worth the effort for field production, as her stalks lack the best chance at successful recombination. We bred it for many generations to figure out how to consistently bulk up flowers, flower earlier, strengthen the stalk, narrow the variability in total cannabinoids, and improve terpene desirability. 
•	Consumer Familiar Heritage 
•	Field Ready Structure
•	Favored for full spectrum extracts

Elektra

Sour G CBG is our latest release for farmers who want to try something new. Its lineage comes from Sour Diesel, but it is mostly sour in name only.

Triangle Kush S1 4X x AVL

Massive dominant colas, incredibly resinous flowers, powerful aromas, potent content, and stout stalks make this one of the most impressive triploid cannabis varieties we've bred to date. An absolute stunner to look at on the plant and in the bag with familiar earthy, gassy, kushy aromas and a fierce kick of lime. We see long internode spacing that is easily filled by chunky flowers. As a triploid this variety is significantly less likely to develop seeds in areas with male pollen present - and these varieties really take the fear out of missing a hermaphrodite indoors.

Auto Skunk THCV

Through many generations of inbreeding and chemical analysis we discovered the needle in the haystack in 2016. This CBG dominant strain was the first commercially available. It is a vigorous grower that produces high yields of large flowers. We bred this specifically for biomass producers and its dry trichomes allow for easy combine harvest.

•   Excellent uniform, field ready structure
•   Ideal for biomass producers
•   Dry trichomes do not gum up combines, allowing for mass harvest

Stem Cell CBG

Auto CBG was the first high CBG content day neutral (autoflower) variety developed for large scale industrial hemp production. These vigorous growers offer farmers the opportunity to grow a short season crop in early spring for a July harvest. Ideal for biomass producers but not for inexperienced farmers. These fast flowering plants are extremely sensitive and require constant attention in their early days.An •    11-12 week life span under ideal conditions

•    Averages around 8% CBG for whole plant biomass under well grown conditions
•    100-200 grams flower yield per plant if allowed to grow to maturity
•    Will remain below 0.3% total THC, even as manicured flower

Auto CBG

*Oregon Tilth Organic Certified*
By far the biggest production gains we’ve seen in our triploid conversion projects are evident in this autoflower CBG producer. With average flower yield increases of over 100% (around 150 grams in the original to almost 400 grams in the triploid), this fast finisher is an excellent choice for early season biomass production. As with all autoflower genetics, they can be tricky to grow and not recommended for novice farmers. On the plus side – no more crawling through fields looking for males or hermaphrodites.

•  Soil emergence to maturity in around 90 days
•  Rapid and vigorous grower capable of producing average yields of 400 grams of flower per plant
•  Total THC compliant on the day of harvest

Auto CBG Seedless

•  Improved flower structure and density
•  Strong sour aroma with some gassy funk
•  Vigorous grower and an excellent producer.

Super Sour Space Candy

*Oregon Tilth Organic Certified*
A highly sought after release for both indoor and outdoor producers alike, this might be our favorite release yet.
