GENETICS REFERENCE
RKS Breeder Documentation
The Amnesia line traces its modern stabilization through a multi-year selection program with phenotype-driven evaluation. The reference phenotype documents the terpene complexity and structural uniformity that define the upper-percentile expression of the line. The variation envelope reflects the realistic spread you can expect from seeds in this stabilized line. The line traces to a Durban Poison × Green Crack cross, with each generation selected to fix the traits that define Amnesia.
- Stabilize potency floor at the lower bound of the THC band
- Tighten cohort variation to ≤ 12% on total cannabinoids
- Preserve aromatic identity across generations
- Maintain trichome density ≥ 28% across cohort

Quality Metrics
Phenotype Consistency & Stabilization Line
Phenotype Consistency
The values reported on this Certificate reflect the top-performing phenotype(A-Pheno #5) selected from a 15-plant cohort of the RKS Amnesia S1 line. Across three production cycles, individual plants from this seed line have fallen within a 10–15% variation envelope on total cannabinoids and total terpene yield when grown under comparable indoor conditions.
Note: phenotype expression is subject to environmental conditions (light, nutrients, VPD, training). These figures are not a guarantee of grow outcome.
Stabilization Status
S1 FEMINIZEDThis line has been stabilized through successive inbred generations with phenotype-driven selection. Trait-locking criteria for the A-Pheno #5 selection:
- Citrus-forward terpene expression (Limonene > 0.40%)
- Total terpenes ≥ 2.0% across cohort
- THCa ≥ 22% under standard indoor SOP
- Sativa structural uniformity · node spacing ≤ 8 cm
- Resistance to powdery mildew (visual screen)
- Flowering time variance ≤ 7 days within cohort
Expected Grow Outcomes
Reference outcomes assume standard cultivation conditions: 600–900 PPFD, VPD 1.0–1.4 kPa, mineral-fed coco substrate, 18/6 veg · 12/12 flower. Outcomes will vary with cultivator skill, environment, and phenotype selection.
Reference Method Notes
Laboratory Authorization
Note for seed buyers · This Certificate analyzes mature, cured flower from a selected reference plant cultivated by the RKS breeding team under controlled conditions. Seed-grown plants may vary slightly from the tested phenotype depending on environment, nutrient regime, and grower input. For best expression of the A-Pheno #5profile, follow the cultivation reference outlined in the “Expected Grow Outcomes” section above.
