Segra International is a Canadian cannabis nursery offering award-winning cannabis tissue culture services, pathogen-tested cannabis clones, and molecular lab testing designed to protect high-value genetics across Canadian and international medical cannabis markets.
Our services include production-ready tissue culture clones, HLVd testing, DNA fingerprinting & genotyping, and access to a commercial cultivar catalogue backed by leading global breeders such as Seed Junky Genetics and Atlas Seed. Segra provides cultivators and medical producers with reliable plant material, validated scientific controls, and proven genetic integrity from initiation through delivery.
Segra delivers cannabis tissue culture clones and production-ready cannabis clones backed by scientific controls and proven commercial workflows. Our services include tissue-culture genetics, cannabis clone supply, cultivar restoration, and long-term genetic storage; helping growers protect valuable strains, improve predictability, and secure reliable planting material across multiple cycles. Segra provides producers a dependable starting point to scale operations in Canada and international medical markets.
Segra’s Molecular Lab Services provide advanced cannabis diagnostics including Hop Latent Viroid (HLVd) testing, DNA fingerprinting/genotyping, and cannabis pathogen testing covering multiple threats proven to affect crop health and performance.
Our molecular science team has created highly sensitive assays in-house and collaborates with leading research to deliver consistent, accurate results trusted across commercial production. These services help growers protect plant health, verify cultivar identity, and make informed decisions that reduce risk and preserve high-value genetics.
Segra offers access to an extensive Tissue Culture Catalogue supported by premium breeder genetics, including exclusive selections from Seed Junky Genetics and leading commercial offerings from Atlas Seed. We work with a number of top breeders globally and are a trusted partner to bring their genetics into the Canadian and global medical markets.
These are true-to-type genetics that are HLVd tested and DNA fingerprinted throughout their lifecycle and again prior to shipping, helping ensure supply-chain integrity and traceability. This gives growers high-value cultivar options backed by tissue culture program integrity, commercial readiness, and proven demand, supporting product differentiation and consistent production outcomes.
Segra International conducts ongoing research across tissue culture biology, molecular diagnostics, and cannabis genomics to advance commercial propagation science and strengthen cultivar integrity for licensed producers worldwide. Our R&D program combines world-leading cannabis tissue culture expertise and advanced molecular capability with international university and industry research collaborations, giving Segra the ability to develop new protocols, evaluate emerging scientific methods, and implement validated improvements directly into commercial workflows.
Areas of research include micropropagation system development, advanced pathogen detection, and genomics-supported identity verification. Examples include work with Temporary Immersion System (TIS) bioreactors to improve tissue culture scalability, DNA fingerprinting and genotyping for identity assurance, and Hop Latent Viroid (HLVd) diagnostic assay development designed for cannabis-specific applications.
Segra’s scientific team actively designs proprietary assays, improves culture performance parameters, and contributes to the advancement of tissue culture methodology for cannabis. This research-first approach enables cultivators to access plant material and lab services based on proven scientific development rather than traditional nursery practices, delivering measurable improvements in genetic integrity, performance predictability, and long-term cultivation success.
Segra connects licensed cultivators and verified buyers through a trusted global sourcing network for high-quality cannabis flower. Our team manages matching, contracting, & logistics, making it easier for buyers to access compliant, lab-tested product while helping cultivators reach new domestic and international markets. Backed by Segra’s unparallelled standards, breeder relationships, and DNA-verified genetics, our procurement service delivers confidence, consistency, and commercial readiness across the supply chain.
