From the RKS Breeding Floor
The CBD MediHaze CBD line has been stabilized for ratio first and yield second. The phenotype on this Certificate represents the top-performing mother in our most recent cohort, selected for elevated CBDa with THCa held below cohort threshold. The variation envelope reflects realistic spread across seeds in the line. The line traces to a Chemdawg × Wedding Cake cross, with each generation selected to fix the traits that define CBD MediHaze.
Breeding Objective · CM-Pheno #6
- Intensify the dominant terpene expression of the line
- Reduce structural variation across cohort
- Improve mold & powdery-mildew resistance under high-humidity flower
- Lock the flowering window with ≤ 7 day cohort variance

Phenotype Consistency & Stabilization Line
Phenotype Consistency
The values reported on this Certificate reflect the top-performing phenotype(CM-Pheno #6) selected from a 10-plant cohort of the RKS CBD MediHaze 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 FÉMINISÉEThis line has been stabilized through successive inbred generations with phenotype-driven selection. Trait-locking criteria for the CM-Pheno #6 selection:
- CBDa ≥ 8% across cohort
- THCa ≤ 0.8% to maintain ratio
- Trichome density consistent across plants
- Mold resistance under high RH
- Cohort variance ≤ 10% on total cannabinoids
- Flower window 8–10 weeks

Disclaimer of variation · Results published in this Certificate represent a selected phenotype of the RKS CBD MediHaze 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 CBD MediHaze 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 CM-Pheno #6 profile, follow the cultivation reference outlined in the “Expected Grow Outcomes” section above.
