From the RKS Breeding Floor
The Fruity Pebbles line has been stabilized through successive inbred generations with phenotype-driven selection. The hybrid character — predictable balance, terpene complexity, manageable structure — has been our breeding objective from cycle one. The phenotype reported here is the top-performing selection from our most recent twelve-plant cohort; the variation envelope on the report shows the realistic spread you can expect from seeds in this line. The line traces to a Green Ribbon × Granddaddy Purple cross, with each generation selected to fix the traits that define Fruity Pebbles.
Breeding Objective · FP-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(FP-Pheno #6) selected from a 14-plant cohort of the RKS Fruity Pebbles 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 FP-Pheno #6 selection:
- Cookies-family aroma fidelity
- Caryophyllene > 0.35%
- Trait stability across 3 production cycles
- Bud density 0.38–0.45 g/mL
- Mid-night-temperature tolerance
- Cohort flower variance ≤ 6 days

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