VETRUX Yunnan cultivation and extraction facility

Our Process

From Seed

to Isolate.

Six phases. One traceable chain. Every batch cultivated, extracted, and verified in Yunnan — from government-approved Yunma-13 cultivars to ≥99.9% pharmaceutical-grade CBD isolate.

Phase 01 · Seed & Nursery

Cultivar Selection & Propagation

We use Yunma-13, a government-approved cultivar with THC < 0.3%. Two propagation methods: seed-based (99% germination in proprietary substrate) and cutting-based (100% female plants from selected mother stock). Our proprietary substrate outperforms market alternatives in root development.

  • Yunma-13 Approved Cultivar
  • 99% Germination Rate
  • 100% Female via Cutting

Phase 02 · Field Preparation

Land & Irrigation Setup

Precision tillage with controlled row spacing. Drip irrigation systems ensure uniform water delivery across varied terrain — critical for consistent cannabinoid profiles.

Phase 03 · Growth Cycle

120-Day Field Journey

From transplant to harvest-ready maturity in 120 days. Density-adjusted planting, weekly field monitoring, and precise harvest timing ensure optimal CBD concentration with THC well below the 0.3% threshold.

Phase 04 · Harvest & Drying

Harvest at Peak Potency

Harvested at optimal maturity and air-dried under controlled conditions to preserve cannabinoid integrity. Flower and leaf material is separated and prepared for extraction.

Phase 05 · Extraction & Purification

From Biomass to ≥99.9% Isolate

Five sub-stages: (1) Biomass dried and ground to optimal particle size. (2) 60% ethanol reflux extraction — 3 passes × 2 hours × 7× solvent ratio. (3) Vacuum concentration at 50–60°C recovers ethanol. (4) Winterization removes waxes; column chromatography (HPD resin, 26 columns) isolates CBD via gradient elution. (5) Crystallization yields ≥99.9% pure CBD isolate.

  • 3-Pass Extraction
  • 26 Chromatography Columns
  • ≥99.9% Purity

Phase 06 · QC & Packaging

Verified, Sealed, Export-Ready

Every batch undergoes in-house HPLC cannabinoid profiling and potency analysis before release. Product is packaged in 5 kg PE bags or aluminum foil bags, sealed in export cartons with full batch documentation (COA, SDS available per order requirements).

  • HPLC Verified
  • 5 kg PE / Foil
  • COA per Batch
