From the RKS Breeding Floor
The Mazar stabilization program at RKS focuses on three traits: resin density, structural compactness, and cold tolerance. The phenotype documented here was selected across three cycles and twelve mothers per cycle, with only the plants meeting all three criteria carried forward. The data on this Certificate reflects the upper-percentile expression you can expect when these seeds are grown under our breeding-room SOPs — a benchmark, not a guarantee. The line traces to a Hindu Kush × Bubba Kush cross, with each generation selected to fix the traits that define Mazar.
Breeding Objective · M-Pheno #2
- Fix the phenotype expression that defines this strain
- Improve resistance to common pathogens under indoor SOP
- Maintain commercial yield bands across cycles
- Reduce flower-window variance ≤ 5 days within cohort

Phenotype Consistency & Stabilization Line
Phenotype Consistency
The values reported on this Certificate reflect the top-performing phenotype(M-Pheno #2) selected from a 14-plant cohort of the RKS Mazar 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 M-Pheno #2 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

Disclaimer of variation · Results published in this Certificate represent a selected phenotype of the RKS Mazar S1 stabilized line under controlled indoor conditions. Individual seedlings may produce plants that vary by approximately 10–15% on total cannabinoids and terpene output, and may express alternate phenotypes within the line. Final cannabinoid and terpene expression is subject to cultivator inputs — lighting, substrate, nutrient regime, environment, and training technique. This document is intended as a reference benchmark of the genetic potential of the RKS Mazar line, not as a guarantee of any individual plant’s outcome.
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 M-Pheno #2 profile, follow the cultivation reference outlined in the “Expected Grow Outcomes” section above.
