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.

(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

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*
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

(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.

*Oregon Tilth Organic Certified*
Backed by a new GG*4 pollinator with bigger buds and better structure, Sour Special Sauce is back is even saucier than the original. This sour beta caryophyllene and limonene terpene twist adds great gassy aromas. Still expect to get those beautiful pink pistils on a flowers and a similar sweet funk in the nose. It's SS mother is known for thriving in moist environments.

•  Added gassy funk with myrcene, beta-crayophyllene, and limonene
•  Highly resinous and a high cannabinoid producer
•  Improved overall production and flower structure

Sour Special Sauce

*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

(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

*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

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

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.

Citrus Slurp Seedless

*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 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*
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

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

(Triangle Kush x Chem D) x AVL

When burnt rubber and barnyard clash with earth, fuel, and lime. These plants are loud, fragrant, and frosty. With its TK & ChemD lineage it can crank out the cannabinoids. An overall excellent producer of dense flowers on a sturdy frame. For those on a budget and looking for the numbers from the field and from the lab, its hard to beat this semi-poly hybrid. Two distinct aroma profiles in pheno's, but consistent finishing times.

Wedding Cake x AVL

Sour lime forward with sweet vanilla cake and gassy goodness make for a mouthwatering combination. Easy to manage structure, heavy trichome production, and big flowers. As a semi-polyhybrid there are a two different phenotypes but it makes for fun hunting. Consistent finishing times and structures with all exhibiting some incredible lime and cake aromas. A great option for bulk cannabinoid production.

Lime Meringue

The nose on this triploid screams - and its resemblance to Skittles is uncanny. Eye catching resin production, bulbous flowers, and a large upright structure. A tasty flashback to the classic Durban with vastly improved flower density and production - and some extra lime and gas thrown in from the AVL parent for good measure. This variety is hard to pollinate and is a great option for outdoor trying to dodge the pollen of a few rogue males.

Terp Poison Seedless

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. 

F1 Hybrid

Terp Poison

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.

(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

*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
