Stabilised genetics. Independently lab-tested. Documented for every Aussie grower.
Every strain we ship into Australia comes with a full Certificate of Analysis — cross-verified by an ISO 17025 cannabis 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 Australian growers know exactly what they're paying for before the seeds hit the medium.
Climate-Tuned Stabilisation
Every line on this page has been carried through at least three filial generations of phenotype-driven selection — F3, F4, F5, IBL, or BX — with twelve mother plants per cycle. Lines are screened against the realities Australian growers face: long sunny outdoor seasons in QLD/NSW, cooler southern conditions in VIC/TAS, and humidity swings on the east coast. What you grow expresses the genetics you bought.
Independent Lab Verification
Each batch is submitted 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 team that bred the line, not pulled from public seed databases.

A working genetics company. Documented for Australia.
Royal King Seeds isn't a re-bagged catalogue. Every strain on this page comes from our breeding floor, stabilised 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 Australian growers can verify exactly what they're paying for.
