From the RKS Breeding Floor
This batch represents the latest stabilization cycle of our 5 Alive mother line. The selected phenotype was chosen across three consecutive cycles for its citrus-forward terpene expression, vigorous sativa structure, and consistently elevated THCa output under controlled indoor conditions. Twelve mother plants were screened; only those falling within the cohort variation envelope on terpene yield and total cannabinoids were carried forward. The data on this report reflects the genetic potential of the RKS 5 Alive stabilized line under our breeding-room SOPs — a benchmark for what growers using these seeds can expect to express in the upper percentile of phenotypes. The line traces to a Thai Landrace × Amnesia Haze cross, with each generation selected to fix the traits that define 5 Alive.
Breeding Objective · 5A-Pheno #6
- 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(5A-Pheno #6) selected from a 10-plant cohort of the RKS 5 Alive 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 5A-Pheno #6 selection:
- Pine-forward expression (Pinene > 0.25%)
- Cerebral, energizing effect profile
- Stable internodal spacing
- Tolerant of long flower windows (10+ weeks)
- Resin density ≥ 25% trichome coverage
- Cohort flowering variance ≤ 8 days

Disclaimer of variation · Results published in this Certificate represent a selected phenotype of the RKS 5 Alive 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 5 Aliveline, 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 5A-Pheno #6profile, follow the cultivation reference outlined in the “Expected Grow Outcomes” section above.
