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.

GTR Seeds / Oregon CBD

Cannabis

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

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.

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

*Oregon Tilth Organic Certified*
A highly sought after release for both indoor and outdoor producers alike, this might be our favorite release yet. This hybrid features our most prized GG#4 conversion and paired it with our Lifter mother. The resulting offspring provide heavy and potent yields of rich and complex aromas in mouthwateringly tasty triploid sour - with rock solid flowers that ooze resin and aroma.

• A heavy producer of both flower and cannabinoids
• Dense and incredibly frosty flowers
• Fruity and sweet with sour beta-caryophyllene-fueled undertones

Sour Lifter Seedless

*Oregon Tilth Organic Certified*
This vigorous growing and heavy producing variety has shown flower increases of over 30% in triploid form, along with cannabinoid increases of almost 20%. While not celebrated for its terpene profile, flowers are large, lime green, and crystal covered. Ideal for biomass producers looking to get the most out of their fields – with a much lower risk of getting seeded.

•  Our highest flower producing CBG plants
•  Excellent field ready structure
•  Drier trichomes less damaging for mechanical harvest

Stem Cell CBG Seedless

*Oregon Tilth Organic Certified*
This production powerhouse already had a sterling reputation in diploid form for its top shelf smokable flower and cannabinoid rich biomass; as a triploid, performance only improves. Greater yields, louder aromas, and increased production from one of our most popular varieties – with a strong resistance to seed production.

• Highest flower and biomass yielder on average
• Proven mold and mildew resistance
• Sweet gassy funk similar to Diesel cannabis lines

Lifter Seedless

*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

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

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

(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

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.

Derailed Seedless

(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

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.

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

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

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

*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

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.
