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.

Hemp CBD

Cannabis

*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

*Oregon Tilth Organic Certified*
 farm favorite, this potent and improved flower producer is reintroduced with a newly selected and stronger parent. It's intoxicating aromas of sour apple and a side of funk are hard to keep contained. With Suver 8's mold and mildew resistance in its lineage this is a forgiving and reliable offering for both trimmed flower and biomass.

•  Potent CBD producer with a reliable resistant background
•  Lime green buds with big appeal on the smokable market
•  Sour apple twisted with even more terpene-loaded funk than the original

Sour Suver Haze

*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

Purple Urkle S1 x AVL

In his early years of cannabis cultivation Seth fell in love with Purple Urkle and subsequently a hefty portion of the student body at a nearby university. Its chunky, skunky flowers were a mainstay in many a dorm rats head stash. Fast forward almost 20 years and a few rounds of inbreeding - a new mother was born. Combined with AVL it boasts bigger production, bulked up flowers, more pungent aromas, and faster finishing times than the original. Skunk and berry still ride supreme but with sour fuel filled notes on the back end. An excellent option for numbers chasers, September harvesters, or anyone trying to bring back an oldie but a goodie.

High Octane Grape

Triangle Kush S1 x AVL

On its own, we find very little remarkable about Triangle Kush - and even in our S1 lines it was hard to truly love her - but it does make for some incredible breeding stock. Paired with our in-house autoflower, the F1 hybrid offspring take on a wealth of improvements in flower structure and production, faster finishing times, resin content, and bag appeal. Expect the familiar kush aromas of popcorn, dank earth, and fuel - with a heavy splash of lime.

Bermuda Triangle

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.

Bermuda Triangle Seedless

(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

Girl Scout Cookies S1 x AVL

A compact plant with big flowers and big yields. Great for indoor growers or anyone shooting for smaller plants that still throw down. Excellent trichome coverage and enticing aromas of sweet cookies with a hint of citrus and fuel on the back end. Dense flowers that are easy to trim and an easy to manage plant structure. A great option for first time growers as well.

(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

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

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

Zkittlez S1 x AVL

Dense and fragrant - these frosting coated candy factories are among our favorites for production and aroma. Easily trainable and lots of golf ball and bigger sized flowers make this variety ideal for both indoor and outdoor growers. Remarkably sweet and sour aromas with a hint of gas. One of our best diploid yielders and solid total cannabinoid numbers.

Private Party

Girl Scout Cookies S1 4X x AVL

This is triploid is no ordinary cookie. One look at the sugar that coats the leaves we knew we'd bred something special. Huge dominant colas, a short stature and resin resin and more resin. Ideal for indoor growers and one of our heaviest yielding plants despite its size, and also a high total cannabinoid yielder. Rock solid flowers equal the smallest pounds you will ever see. Cookies aromas with a heavy dose of citrus and fuel - we called it laughing gas for a reason.

NOX Cookies Seedless

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.

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.

*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

•	Ideal for humid climates with strong mold resistance

Special Sauce

*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

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

*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

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

*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

(ChemD x Lemon Party) x AVL

The mother plant in this cross exhibits the most eye-watering stench we've come across in a cannabis plant - unmistakably ChemD centric somehow tainted further by citrus. Paired with AVL there are vast production and structure improvements, but the smell only gets funkier. Very nice dominant cola's and excellent resin coverage. As a 'half' polyhybrid some plants will boast more characteristics of the Chem and some the Lemon Party - which have very different cannabinoid profiles.

Chemical Party

(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.
