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

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

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.

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

(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 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

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.

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.

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

(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

(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

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

*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

*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

(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

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.

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

*1st Place Credible Cultivar 2020 Cultivation Classic*
*3rd Place 2020 Cultivation Classic*
*3rd Place 2020 High Times Hemp Cup*

(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

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

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

*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

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.
