GENETICS REFERENCE
RKS Breeder Documentation
The Jager stabilization program at RKS focuses on three traits: resin density, structural compactness, and cold tolerance. The reference phenotype documents the upper-percentile expression of these traits in the stabilized line. This is a reference benchmark for what growers can reasonably expect from these seeds, not a guarantee, and not an independent per-lot COA. The line traces to a LA Confidential × Bubba Kush cross, with each generation selected to fix the traits that define Jager.
- 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(J-Pheno #6) selected from a 14-plant cohort of the RKS Jager Auto 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
AUTO F5This line has been stabilized through successive inbred generations with phenotype-driven selection. Trait-locking criteria for the J-Pheno #6 selection:
- Earth-forward terpene expression
- Trichome coverage ≥ 30%
- Stable purple/dark coloration where genotype carries it
- Mid-canopy bud uniformity
- Mold resistance under high RH
- Cohort variance ≤ 7 days
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 J-Pheno #6profile, follow the cultivation reference outlined in the “Expected Grow Outcomes” section above.
