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.

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.

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

*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.

Auto Skunk THCV

*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

Take a walk in the pines with Pine Walker Seedless, the highest varin-content hemp variety on the market. We crossed our heralded “Special Sauce” production mother with a high varin content type I variety, then went to work inbreeding, testing, and refining until growth habits, flavor, and--most importantly--ultra-high CBDV content were all locked in. Then we converted the subsequent plant into a tetraploid by doubling its genome (non-GMO). The result is a plant that will make your eyes water with joy from its pungent pine tar flavor profile. When combined with our VERB pollen donor, expect  triploid hybrids with unrivaled CBDV content--and a nose of pine, cream, and berries. 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
• Pleasantly powerful aromas of pine, cream, and berries
• Extremely limited release

(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

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

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

(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.

Zkittlez S1 4X x AVL

Our in-house favorite for its high yielding structure and exotic tropical fruit aromas. This triploid produces very large dense flowers on an easy to manage plant. Expect trichomes that ooze their way down the leaves and pungent sweet and sour notes. A production power house both indoors and out and a fantastic smoke.

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

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

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

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.

NOX Cookies

(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.

Chem Spill

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.

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

(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.

Citrus Slurp

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.
