Bred in-house. Tested independently. Documented for every grower in Canada.
Every strain we ship from our British Columbia breeding floor comes with a full Certificate of Analysis — cross-verified by an ISO 17025 lab and co-signed by our master breeder. Pick any strain in the catalogue below to see the report behind your seeds.
Three guarantees behind every seed
Three independent verifications combined into one document — published openly so Canadian growers know exactly what they're buying before it goes in the soil.
Climate-tuned Stabilization
Every line on this page has been carried through at least three filial generations of phenotype-driven selection inside our BC breeding facility — F3, F4, F5, IBL, or BX — with twelve mother plants per cycle. Lines are screened against Canadian growing realities (short outdoor seasons, cool nights, high-RH indoor flowers), so what you grow expresses the genetics you bought.
Independent Lab Verification
Each batch is sent under chain-of-custody to an ISO/IEC 17025-accredited cannabis lab for cannabinoid potency (HPLC-DAD), terpene profile (GC-FID), and an 8-category safety screen — pesticides, heavy metals, microbials, mycotoxins, residual solvents, foreign matter, filth, and water activity. No ambiguity, no rounding.
Master-Breeder Authority
Our master breeder co-signs every Certificate alongside the laboratory director. The narrative on each report — selection criteria, breeding objective, cohort variation envelope — is documented by the Canadian team that bred the line, not pulled from public seed databases.

Royal King Seeds isn't a re-bagged catalogue. Every strain on this page comes from our breeding floor in British Columbia, selected and stabilized by the same team that signs the Certificates. The reports you see here are the same documents we use internally to track phenotype consistency cycle over cycle — published openly so Canadian growers can verify exactly what they're paying for.
