From the RKS Breeding Floor
This Certificate documents the upper-percentile phenotype of our Lamborghini stabilized line. Our breeding criteria for this strain prioritize hybrid balance: no single terpene dominating the profile, trichome density above the cohort minimum, and a tight flower-time window. Twelve mother plants were screened in this cycle; the results here reflect the chosen pheno carried forward. The line traces to a Girl Scout Cookies × Pineapple Express cross, with each generation selected to fix the traits that define Lamborghini.
Breeding Objective · L-Pheno #5
- 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(L-Pheno #5) selected from a 13-plant cohort of the RKS Lamborghini 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 L-Pheno #5 selection:
- Balanced terpene expression (no single >50% of profile)
- Predictable hybrid effect profile
- Cohort variation ≤ 12% on total cannabinoids
- Trichome density ≥ 28%
- Resistance to common mildew strains
- Flower window 8–10 weeks

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