From the RKS Breeding Floor

The Blue Dream line traces its modern stabilization back to a multi-year selection program at our breeding facility. The phenotype reported here represents our top-performing mother across the most recent production cycle, hand-selected for terpene complexity and structural uniformity. The cohort screen — twelve plants per cycle — produces the variation envelope you see in the phenotype-consistency section. This Certificate documents the upper-percentile expression of the line. The line traces to a Tangie × Thai Landrace cross, with each generation selected to fix the traits that define Blue Dream.

Breeding Objective · BD-Pheno #1
  • 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

RKS internal selection criteria · not tested by lab

Phenotype Consistency

The values reported on this Certificate reflect the top-performing phenotype(BD-Pheno #1) selected from a 13-plant cohort of the RKS Blue Dream 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=13)Reference pheno = THC 16.4%
14.7% (low)17.9% (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 FÉMINISÉE

This line has been stabilized through successive inbred generations with phenotype-driven selection. Trait-locking criteria for the BD-Pheno #1 selection:

  • Citrus-forward terpene expression (Limonene > 0.40%)
  • Total terpenes ≥ 2.0% across cohort
  • THCa ≥ 22% under standard indoor SOP
  • Sativa structural uniformity · node spacing ≤ 8 cm
  • Resistance to powdery mildew (visual screen)
  • Flowering time variance ≤ 7 days within cohort

♛ 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-745. The data herein is published as a reference benchmarkfor the RKS Blue Dream 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 Blue Dream 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 Blue Dream 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 BD-Pheno #1 profile, follow the cultivation reference outlined in the “Expected Grow Outcomes” section above.
