Stabilised genetics. Documented openly for every UK grower.
Every strain we ship into the UK comes with a breeder-documented genetics reference, aggregating publicly-reported lab data, breeder specifications, and grower-community results. These are reference benchmarks for the stabilised line. Pick any strain in the catalogue below to see the reference behind your seeds.
What “genetics reference” means here
Three documentation sources combined into one reference benchmark — published openly so UK 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 UK growers face: a short outdoor window from roughly April to October, cool summers, and the damp late-season conditions that make mould resistance and a fast finish matter more here than raw yield potential. What you grow expresses the genetics you bought.
Reference Benchmarks
Each genetics reference aggregates breeder-published specifications, publicly-reported third-party lab data for the strain family, and grower-community results — cannabinoid ranges, terpene profile, and an 8-category safety summary. These are reference benchmarks for the stabilised line, NOT independent ISO/IEC 17025 certificates of analysis for the specific seed lot you receive.
Breeder Documentation
The Royal King Genetics breeding team documents every line — selection criteria, breeding objective, cohort variation envelope. The narrative on each report comes from the team that bred the line, not pulled from public seed databases alone.

A working genetics company. Documented for the UK.
Royal King Seeds isn't a re-bagged catalogue. Every strain on this page comes from our breeding floor, stabilised and documented by the same team. The references you see here aggregate breeder specifications, publicly-reported third-party lab data, and grower-community results — they're reference benchmarks for the stabilised line, not independent per-lot certificates of analysis, published openly so UK growers know exactly what they're paying for.
