What Is a Cannabis Nursery?
A cannabis nursery is a licensed business that maintains, propagates and supplies cannabis starting material to authorized cultivators. Depending on its capabilities, a nursery may provide tissue culture plantlets, rooted clones, mother stock, seeds, genetic preservation, cultivar trials and plant-health testing.
Segra operates as a science-led cannabis nursery. Rather than relying on conventional mother plants and repeated vegetative cloning alone, Segra holds genetics as in-vitro tissue culture stock, confirms cultivar identity by DNA, screens for pathogens in its own molecular laboratory, and multiplies plants to order.
What Segra Provides
Cannabis Tissue Culture Plants
Segra produces laboratory-propagated cannabis tissue culture plants for licensed commercial operators, using either cultivars from Segra's catalogue or the client's own genetics. Tissue culture gives cultivators a controlled starting point for propagation, supports recurring production schedules, and reduces dependence on large in-house mother rooms.
- Cultivar-specific initiation, multiplication, rooting and acclimation workflows
- Recurring plantlet supply, mother-stock refreshment and production scaling programs
- DNA verification and pathogen testing built into the propagation process

Production-Ready Cannabis Clones
Segra supplies rooted cannabis clones for licensed cultivation programs. Clone programs are planned around cultivar, quantity, production timing, destination, documentation and the receiving facility's requirements. Formats and lead times vary by cultivar, program type and jurisdiction.
Cultivar Restoration and Genetic Storage
Commercial genetics accumulate risk over time through long-term mother-room maintenance, repeated cloning, mislabelling and pathogen exposure. Segra initiates eligible client genetics into tissue culture, applies restoration workflows, establishes DNA-verified in-vitro material, and maintains that genetic stock for future production, research or breeding.
Commercial Cannabis Genetics
Segra gives licensed operators access to a curated catalogue of commercial cannabis cultivars from its own collection and from recognized breeder partners. Catalogue availability varies by jurisdiction, plant format, licensing rights and production schedule. Genetics supplied through Segra's nursery programs carry a documented chain of identity, pathogen testing records and DNA-based verification.
Molecular Testing and Genetic Verification
Segra runs its own molecular biology laboratory in Richmond, British Columbia. Testing is performed in-house, not outsourced. Services include Hop Latent Viroid (HLVd) testing, cannabis pathogen testing, DNA fingerprinting and genotyping. These tools let operators quantify plant-health risk, confirm cultivar identity, investigate suspected mix-ups and protect high-value genetic assets.

Finished Cannabis Flower
Segra produces finished cannabis flower from its own tissue culture stock at its Kelowna, British Columbia production facility and distributes it to licensed buyers worldwide. Because the flower is grown from Segra's own DNA-verified plants, the cultivar identity can be traced from in-vitro stock through propagation and cultivation to the packaged lot — the same genetic traceability Segra applies to its nursery plants, extended to finished product.
Every lot is supplied with a certificate of analysis. Flower produced in Canada is tested by accredited Canadian laboratories; flower sourced through Segra's global cultivator network is supplied with the applicable third-party COA for that market.
Tissue Culture Plants vs. Conventional Clones
Both are commercial starting material. They differ in how they are produced, how genetics are stored between cycles, and what can be verified before delivery.
| Factor | Tissue culture plant | Conventional clone |
|---|---|---|
| Source material | Small explant propagated in vitro under sterile laboratory conditions | Cutting taken from a living mother plant |
| Where genetics live between cycles | In-vitro stock in the laboratory; no mother room required | Active mother plants occupying production space year-round |
| Pathogen exposure during propagation | Sterile closed environment; low exposure to tools, vectors and handling | Open nursery environment; exposure to tools, staff and insect vectors |
| Identity verification | DNA fingerprinting against the reference profile before release | Typically label-based unless separately tested |
| Scaling | Multiplied on demand from stored stock | Limited by mother plant count and cutting recovery time |
| Lead time | Longer for first initiation of a new cultivar; short once stock is established | Short, provided healthy mothers are already in production |
| Best suited to | Preservation, restoration, recurring supply, multi-site and export programs | Immediate fill of a known cultivar from existing in-house stock |
Tissue culture does not replace good cultivation, biosecurity or quality systems. Plant performance still depends on genetics, environment, nutrition, crop steering, sanitation and the receiving facility's operating practices. Segra's role is to provide a verified, tested and well-documented starting point.
Premium Breeder Partners and Award-Winning Genetics
Segra works with a selected group of premium breeder partners whose cultivars have earned recognition in competition and in commercial production. Partner genetics are brought into Segra's tissue culture system, DNA verified against the breeder's reference profile, and pathogen tested before they enter the catalogue — so the cut a cultivator receives is confirmed to be the cut the breeder released.

Pathogen Testing and DNA Traceability
What Segra provides is testing and documentation: plant material is pathogen tested in Segra's internal molecular laboratory against the panel defined for each program, and finished flower is supported by certificates of analysis from accredited third-party laboratories. Testing reduces and documents risk. It cannot certify the permanent absence of every pathogen, and plant health after delivery depends on the receiving facility's biosecurity, sanitation, vectors, staff and incoming materials.
Hop Latent Viroid (HLVd) Testing
Segra's HLVd assay is RT-PCR based, was developed in-house by Segra scientists, and is run in Segra's own laboratory in Richmond, British Columbia — not outsourced. The lab has performed more than 15,000 HLVd tests across Segra's nursery and partner inventories. Results are returned within three business days of sample receipt. Test kits are sold in 10-packs at $40 per sample and 100-packs at $32 per sample, including the kit, shipping to your facility, analysis and final reporting.

DNA Fingerprinting for Genetic Traceability
DNA fingerprinting is the backbone of Segra's traceability system. Every cultivar entering Segra's nursery programs is genotyped and matched against the reference profile for that cultivar. That reference profile is retained, which means Segra can confirm that the plant leaving the facility is genetically identical to the material that entered it, resolve disputes about mislabelled or misnamed cuts, distinguish genuine breeder cuts from look-alikes circulating under the same name, and extend that verified identity forward into finished flower produced from the same stock.
For cultivators, this is what converts a cultivar name from a label into a verifiable claim — the difference between being told a plant is a particular cut and being able to demonstrate it.

Does Segra sell cannabis plants?
Yes. Segra supplies cannabis plant material to licensed and otherwise authorized commercial operators. Formats include tissue culture plantlets, rooted clones, mother stock and catalogue genetics. Segra does not sell to consumers or unlicensed buyers.
Does Segra sell finished cannabis flower?
Yes. Segra produces finished cannabis flower from its own tissue culture stock at its Kelowna, British Columbia production facility and distributes it to licensed buyers worldwide. Because the flower is grown from Segra's own DNA-verified tissue culture plants, the cultivar identity can be traced from in-vitro stock through to the packaged lot. Finished flower is supplied with certificates of analysis from accredited laboratories.
What is a cannabis tissue culture plant?
A cannabis tissue culture plant is propagated in vitro under sterile laboratory conditions from a small piece of selected plant material. After multiplication and rooting, the plantlet is acclimated for transfer into a nursery or cultivation environment. Tissue culture is used for genetic preservation, cultivar restoration, and consistent large-scale plant supply.
What is the difference between a tissue culture plant and a conventional clone?
A conventional clone is a cutting taken from a living mother plant and rooted in a nursery. A tissue culture plant is propagated in a sterile laboratory from a small explant before being acclimated. Conventional cloning requires ongoing mother room space and can accumulate pathogens and drift over repeated generations, while tissue culture allows genetics to be held as in-vitro stock, screened molecularly, and multiplied on demand.
Can Segra put a customer's own cultivar into tissue culture?
Yes, subject to technical assessment, proof of legal ownership or authorization, plant health status and commercial terms. Segra's Regenerate & Preserve program initiates client genetics into tissue culture, applies restoration workflows and maintains the resulting verified stock for future production, breeding or research.
Does Segra test for Hop Latent Viroid?
Yes. Segra provides Hop Latent Viroid (HLVd) testing using an RT-PCR assay developed in-house and run in Segra's own molecular laboratory in Richmond, British Columbia, rather than outsourced. Segra's lab has performed more than 15,000 HLVd tests across its nursery and partner inventories, and returns results within three business days of receiving samples.
How much does HLVd testing cost?
Segra's HLVd test kits are sold in multipacks: a 10-pack at $40 per sample and a 100-pack at $32 per sample. The price includes the sampling kit, shipping to your facility, laboratory analysis and final reporting. Ordering two or more packs qualifies for a 10% discount.
How does Segra verify cannabis genetics?
Segra uses DNA fingerprinting and genotyping to confirm cultivar identity and establish genetic traceability. Genetics entering Segra's nursery programs are DNA verified against the reference profile for that cultivar, which allows Segra to confirm that the plant leaving the facility is genetically the same cultivar that entered it and to investigate suspected mix-ups or mislabelled material.
Are Segra's plants disease free?
No responsible nursery can describe plant material as disease free, and Segra does not make that claim. Segra's plant material is pathogen tested in its internal molecular laboratory against the panel defined for each program, and finished flower is supported by certificates of analysis from accredited laboratories. Testing reduces and documents risk; it cannot certify the permanent absence of every pathogen, and plant health after delivery also depends on the receiving facility's biosecurity, sanitation, vectors and incoming materials.
Which breeders does Segra work with?
Segra works with premium breeder partners including GreenShock Farms, Grounded Genetics, Seed Junky Genetics, Purple City Genetics and Atlas Seed. Availability of any individual cultivar depends on licensing rights, jurisdiction, plant format and production schedule.
Which countries does Segra ship to?
Segra has shipped to Canada, the United States, Germany, Portugal, the United Kingdom, Spain, Greece, Switzerland, North Macedonia, Israel, Ukraine, South Africa, Thailand, New Zealand, Australia, Colombia and Costa Rica. Segra can ship to any country legally permitted to import plant material or finished flower, subject to import and export permits, phytosanitary documentation and destination country rules.
How long does cannabis tissue culture initiation take?
Timelines depend on cultivar response, incoming pathogen status, the initiation method selected and the testing and multiplication required. A commercial initiation and restoration program generally takes several months before stable, verified in-vitro material is ready for scale-up, and Segra confirms an estimated timeline for each cultivar after technical assessment.
Who can buy from Segra?
Segra supplies licensed and otherwise authorized cannabis businesses, including licensed cultivators, nursery operators, medical cannabis producers, breeders and genetic owners. Eligibility depends on the buyer's jurisdiction, licence type, intended use, genetic rights and applicable import, export and cannabis regulations.
