From the RKS Breeding Floor
Our Afghani line was hand-selected for the resin-coated, compact phenotype that defines this strain at its best. Cohort screening across multiple cycles produces the variation envelope shown in the consistency section; only mothers falling within the envelope are kept in the line. This batch reflects the genetic potential of the RKS Afghani stabilized line. The line traces to a Granddaddy Purple × Bubba Kush cross, with each generation selected to fix the traits that define Afghani.
Breeding Objective · A-Pheno #5
- 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

The values reported on this Certificate reflect the top-performing phenotype(A-Pheno #5) selected from a 11-plant cohort of the RKS Afghani 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.
Cohort variation (n=11)Reference pheno = THC 21.5%
18.7% (low)23.5% (high)
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:
- Resin-dominant (myrcene > 0.55%)
- Heavy body-effect uniformity
- Compact node spacing ≤ 6 cm
- Cold-tolerant under nighttime drops (15°C)
- Bud density ≥ 0.40 g/mL
- Cohort flower variance ≤ 5 days

♛ RKS Genetics Authority Statement
The genetic line analyzed in this Certificate was bred, selected, and stabilized by the Royal King Seeds Breeding Team at our in-house breeding facility. This batch was independently verified by CANNASAFE LABORATORIES under chain-of-custody protocol CAN-COC-597. The data herein is published as a reference benchmarkfor the RKS Afghani stabilized line — a documented standard against which every seed in this lot has been bred to perform.

Disclaimer of variation · Results published in this Certificate represent a selected phenotype of the RKS Afghani 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 Afghani 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 A-Pheno #5 profile, follow the cultivation reference outlined in the “Expected Grow Outcomes” section above.
