We eliminate the risks and variables of commercial cultivation by providing our customers with verified, stable genetics and vigorous, disease-free clones.




Leading-edge technology for cultivar and pathogen identification for growers, breeders, and nurseries.



Our experienced team has been focused on perfecting plant propagation for decades.  3Rivers Nursery is a partnership with JRT Nurseries, one of the largest and most reputable plant tissue culture nurseries (Hemp Tissue Culture) in North America producing over 12 million plants per year.

Washington is the home of our licensed facility, but we ship premium tissue cultured plants all over the US and world. From Washington to Florida, we’re here to help hemp tissue culture farmers de-risk their operations, scale their production safely, and reap the benefits of this exciting crop.

Almost every clonally-produced crop has moved to tissue culture plant starts for a reason. Plants that are starting disease-free tend to be highly vigorous throughout their life cycle and focus more energy on growth and secondary metabolite production, augmenting the performance of the crop and economic return.

We work with established breeders in every region of the US to ensure that our genetics will keep you compliant and help you succeed where you grow

How we add value
to our customers

Financial Performance

Stable genetics and vigorous, disease-free clones of seeds to maximize the value of derived secondary metabolites (ex. CBD, CBG)

Every plant is female, avoiding any wasted resources on male plants or seeds that don’t germinate.

Our process is highly scalable, allowing you to continually and sustainably grow your operations

Risk Mitigation

Clonal plants are consistent to avoid non-compliance and plants in a crop testing hot.

Reduce risk of crop failure and diminishment from pest and pathogen pressures.

Reduce chance of failing strict pesticide testing with clean, laboratory produced plants.

Pathogen Detection – Genie Lab

Plant pathogens can affect all plant tissues and wipe out entire operations. Many infections can go undetected in asymptomatic plants only to decimate crops in the later stages of growth, such as hop latent viroid (HpLVd). The quickest and most sensitive method to test for pathogens is a genetic analysis known as polymerase chain reaction (PCR). Our pathogen detection service screens samples with PCR for unique genetic markers of fungal, bacterial, and viral cannabis pathogens to providing clean plants and peace of mind.

Currently, our lab provides accurate, high throughput pathogen testing on plant tissue for cannabis and hemp. We are expanding to other small fruits in the near future.

We perform an 12-virus panel and 36-fungal panel test on plant tissue to find out what is affecting your plants.

Current turnaround time for testing samples is 3-5 business days – please contact us for an estimate

Cultivar Identification

Genetic markers capable of affordably and conclusively verifying strains based on genetic heritage have long been sought. To that end, we have developed a DNA fingerprinting platform providing the tools necessary to verify cultivar identity, determine a cultivar’s position within the cannabis family tree, and test for undesirable mutations arising during clonal propagation.

We provide high throughput genetic identification to the cannabis and hemp industries. We are expanding to other small fruits in the near future.

Genotyping identifies a variety or group of closely related varieties (or strains) based on a piece of genetic code unique to that individual or group.

Varieties can slowly change over time (strain drift). The genetic markers we use have high mutation rates and serve as proxies to let a grower know when a strain needs to be re-introduced from a backup.

Hemp Tissue Culture Services

Genetic Storage

Back up valuable production or seed lines. Off-site storage to secure germplasm in the event of a catastrophic facility failure (ex. Power outage, fire, HVAC failure). Clean copies provided back regularly.

Clean Mother Stock

Regular provision of clean mother stock to support internal propagation programs. Ensure quality performance using cuttings derived from tissue culture mother plants. De-risk operations by decreasing pathogen loads in facility nursery operations.
