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.

Durban Poison S1 x AVL

A tasty flashback to a timeless strain with better production and faster finishing times. Durban Poison has long been a favorite for it's fierce terpinolene dominant nose - but we've never been impressed with the flower structure. Even in our S1 lines we never quite found one that trimmed up the way we'd want a flower. Crossed with our AVL pollinator we see much improved structure and a somehow even more eye watering sour aroma.

Terp Poison

*Oregon Tilth Organic Certified*
Armed with a new and bulked up GG*4 pollinator in its lineage, SSSC is an extra sour twist on an already sour flower. Bigger and better structure than the previous and an all out great performer and producer in our trials. With a beta-caryphylene fueled terpene profile the nose hits hard and its flowers offer excellent bag appeal. One of our fastest finishing strains.

•  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*
One of our in-house favorites, this triploid features our improved for 2021 GG*4 pollinator. Suver 8’s sweet smells shine through in a delicious yet still oh so sour offering. This genetic boasts similar mold and mildew resistance as the original but with elevated olfactory compound production, improved density, structure, and in triploid flower form.

•  Potent CBD producer with a huge appeal on the smokable market
•  Excellent mold and mildew resistance
•  Sour apple twisted with even more terpene-loaded funk than the original

Sour 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*
A highly sought after release for both indoor and outdoor producers alike, this might be our favorite release yet. This hybrid features our most prized GG#4 conversion and paired it with our Lifter mother. The resulting offspring provide heavy and potent yields of rich and complex aromas in mouthwateringly tasty triploid sour - with rock solid flowers that ooze resin and aroma.

• A heavy producer of both flower and cannabinoids
• Dense and incredibly frosty flowers
• Fruity and sweet with sour beta-caryophyllene-fueled undertones

Sour Lifter Seedless

*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 vigorous growing and heavy producing variety has shown flower increases of over 30% in triploid form, along with cannabinoid increases of almost 20%. While not celebrated for its terpene profile, flowers are large, lime green, and crystal covered. Ideal for biomass producers looking to get the most out of their fields – with a much lower risk of getting seeded.

•  Our highest flower producing CBG plants
•  Excellent field ready structure
•  Drier trichomes less damaging for mechanical harvest

Stem Cell CBG 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.

*1st 2019 Place Oregon Growers Cup*

(SH50 x ERB)
Farmers will be rewarded with vigorous bushy, upright growth patterns in the vegetative phase that can easily fill 6' centers. By late August, fields will be full of large, oily “goldilocks” buds, perfect for the international trimmed hempflower market. The flavor is sweet funk, with some hints of fuel—very sought after by consumers! Pound for pound, this just might be the most lucrative CBD producer available.
•	Highest yielder and largest plants
•	Ideal for biomass, but also provides big dense “A” grade flowers
•	Sweet gassy funk, reminiscent of a diesel THC strain

Lifter

Our potent new Chem4 mother boasts the most impressive structure we've bred to date; teamed with our GG#4 conversion, the combination is unstoppable. Plenty of gas with chem cleaner and citrus aromas. Growers can hit great production numbers with large, dense, and easy to trim flowers. A fast finishing line with high total cannabinoid production capabilities.

• Jam packed with fuel and citrus aromas with a chemical bite
• Solid green golf ball and larger sized flowers with very little leaf
• An 8-week strain with rapid flower development

Sour Chem

ChemD S1 x AVL

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.

Barnyard High Test

Sour Diesel x AVL

This famed strain is a total pain in the ass to breed with - and we have never been overly impressed with the outcome with our previous crosses. Fortunately AVL came to the rescue for this semi-polyhybrid. Bigger production numbers, significantly faster flowering, better structure, and mix of aromas from straight lime to straight gas - and some nice combos in between. Growers will find greater variation between plants than with our other true F1's, but we are proud to bring back some old school Sour D flavors in early finishing form.

Gasolime

*1st Place 2020 Cultivation Classic*
*1st Place 2019 Cultivation Classic*
*1st Place 2019 WeedCon Buyers Cup*

(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

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. It produces slightly less dense flowers than the White CBG and a stronger nose than Stem Cell. Expect the same vigor, strength, and reliability of all of our other lines with a new twist on CBG.

•   Enticing crystal covered flowers
•   High CBG yielding plant capable of producing upwards of 20% CBG
•   While not an overpowering aroma, the nose is unique relative to any other CBG varieties on the market.

Sour G CBG

*Oregon Tilth Organic Certified*
One of our most exciting new offerings for 2021, this combo combines tropical goodness with the gassy funk of our new and improved GG*4 pollinator. The terps are the real deal in this hybrid making adding appeal to the already smokeable hit, Hawaiian Haze. A vigorous grower and a solid producer.

•  Brand new flavors for the smokeable market
•  Exotic tropical aromas with ample undertones of fuel
•  Excellent bag appeal with brilliant green flowers

Sour Hawaiian Haze

*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

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

*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

*2nd Place 2020 Cultivation Classic*
*2nd Place 2019 Oregon Growers Cup*

(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

“Really Nice Auto” was the first high CBD and terpene content autoflower variety on the industrial hemp seed market. These quick-flowering plants are a great option for biomass and cut flower producers.

*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

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
