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.

Cannabis

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

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.

*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

(Special Sauce x ERB)
Our flagship line, containing exotic astringent berry smells, beautiful pink pistils, and some of the highest oil returns of any industrial hemp on the planet. The flavors are otherworldly. and it is a true gift to smell a whole field flowering! Many claim to have “it”–trust us, they don’t! This mom has never been released and is only used for breeding. Smaller flowers then others but they are coated in resin.

•	Our highest average CBD content, often reaching over 20%
•	Top seller in the international trimmed flower market
•	Excellent for full spectrum oil extraction
•	Ideal for humid climates with strong mold resistance

Special Sauce

*Oregon Tilth Organic Certified*
The legacy lives on in triploid form for one of our most award-winning and reliable varieties. Growers are rewarded with solid yields, exotic aromas, and beautiful bag appeal – from a nearly seed-free plant proven to have the highest resistance to molds and mildews in our lineup.

•  Excels in moist climates and exhibits strong resistance to botrytis
•  A known high-CBD producer, with specimens reaching up to 25%
•  Exotic sour apple flavor created by farnsene and beta-caryophyllene terpene content

Suver Haze Seedless

*Oregon Tilth Organic Certified*
This production powerhouse already had a sterling reputation in diploid form for its top shelf smokable flower and cannabinoid rich biomass; as a triploid, performance only improves. Greater yields, louder aromas, and increased production from one of our most popular varieties – with a strong resistance to seed production.

• Highest flower and biomass yielder on average
• Proven mold and mildew resistance
• Sweet gassy funk similar to Diesel cannabis lines

Lifter Seedless

*Oregon Tilth Organic Certified*
Already revered for its large dense flowers and gorgeous bag appeal, White CBG’s triploid counterpart exhibits a stronger, more diesel-filled nose and bumped-up yields. With added essential oil production, its frosted white and compliant flowers also gain more stickiness than the original.

•  Heavy producer of show stopping A grade flower
•  Our highest testing CBG flower, but will still remain below 0.3 Total THC
•  Large colas but a plant better suited for drier climates

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.

(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

*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

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

(Sour Tsunami x ERB)
The CBD-dominant Sour Tsunami cut used in this cross has the strongest stalk of any plant we have grown and sports a unique, terpinolene-forward flavor similar to Original Glue and the Sour Diesel/Chem/OG lines. Outcrossing this variety to our ERB line yields a unique flavor profile reminiscent of sour candy from outer space. If interstellar travelers needed a sweet and sour snack to keep their head right during their adventures, this would be the one! Stock is very limited on this variety!

•	Rock Hard, golf-ball sized flowers that stay intact in trim machines
•	An excellent choice for cut flower with “Kush” like fragrances
•	A huge producer, ideal for drier climates

Sour Space Candy

(Chem4 x KAP)
*Certified Organic*

Our new and exotic Chem4 mother packs a powerful citrus punch in this beautifully structured hybrid. Robust and well-spaced flowers with minimal leaf waste mean growers can expect heavy yields of A-grade flower. A surefire hit for smokable and a completely fresh flavor from the new Chem4 mother.

• Pungent citrus aromas with mild hints of sweet fruit
• Large, trichome covered, and easily trimmable flowers
• A hefty producer with a unique aroma and heavy resin content

This CBD dominant variety matures in around 8 weeks of flowering time, or mid September if planted outdoors in early June. Expect CBD to THC ratios of around 25/1.

Chemberry

Trainwreck S1 4X x AVL

Its impossible to ignore how much more resin we see on the triploids in comparison to the diploids - and this 3x plant is a shining example. Denser flowers, even louder sour and spicy pepper notes, and seriously bulked up production. The old school 'Wreck' flavors of this jewel are hard to come by and it definitely hits hard enough to derail even a seasoned consumer. As a triploid the chances of finding seeded flower is significantly less.

Cali Orange S1 4x x AVL 

Gobs of gooey citrus resin ooze from this rock solid and prolific flower producer. One of our in-house favorites for not only its powerful and exotic citrus zing, but also for how loaded its branches become. Shorter in stature than some of our other varieties but a fantastic option for indoor producers or those limited on space. As a triploid we see significantly more crystal formation - and its chances of producing seed are far lower than its diploid counterpart. Easy to trim - and even harder to throw out the frost covered leaves that come off of it.

(W19 x KAP)

*Certified Organic*

 A sweet, frosty and fast finishing combination of two heavy producing and highly inbred lines. Large dominant colas, great trichome production, and solid density make this line a fantastic option for the smokable hemp flower. Super early finishing times help for a staggered harvest.

• Sweet and creamy aromas of vanilla, berries, with a touch of gas
• Golf ball and larger sized dried flowers with a high flower to leaf ratio
• One of our fastest finishing CBD varieties ever produced

This CBD dominant variety matures in around 7-8 weeks of flowering time, or early September if planted outdoors in early June.  Expect CBD to THC ratios of around 25/1.

Cakeberry Brulee

Cali Orange S1 x AVL 

The Cali-O S1 mother we selected for this cross looks more like an autoflower at maturity than a photo - short, squat, and a flower on a stick. Hybridized with AVL and it took on entirely new form with greater vigor, slightly larger node spacing, and an an even more tantalizing combination of sweet and sour citrus - with a hint of vanilla. An excellent producer of A grade flower and a really fun and easy plant to grow.

Foul Chem funk meets AVL sour for an incredibly vigorous growing, heavy producing, and cannabinoid packed power house producer. The name says it all, smells like a barnyard with a spattering of fuel and the content to get you high test scores. Grower beware, these plants can grow to become incredibly large and take some serious training indoors.
