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

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
Finishing: Mid to Late September Outdoors


*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

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.

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

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.

Private Party

(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

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.

Terp Poison Seedless

(W19 x KAP)

• 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.

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.

Chem Spill

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.
