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

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

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 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

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

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

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.

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

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

Auto CBG

“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.

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*
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

A mouth puckering sour citrus and gassy hybrid featuring our GG#4 pollinator. This line has the loudest aromas we've ever produced. Opening a jar is a kick in the face. Consistent shape and structure, large, dense lime green flowers, and blazingly fast finishing times. An excellent total cannabinoid producer with plenty of resin.

• Powerful and pungent lime and gas aromas with a hint of cream
•. Our fastest finishing CBD line to date, with late August to early September finishes possible
. Brilliant green flowers with minimal variation and highly productive structure


Sour Brulee 

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

*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

Pine Walker Seedless

*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

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.

Trainwreck S1 x AVL

This blast from the past has a nearly debilitating effect on many of us - hence the title. Telltale aromas of terpinolene hit the nose first with undertones zesty black pepper and a hint of fuel.  Improving on this old school favorite has been a dream for years and its unique aroma is sure to be a standout in your garden. Great production and a big plant.

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

(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

*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

(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

*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
