Quality & Specifications
Technical Standards That Turn Material into Trust
This page translates Pham Le Group’s premium positioning into measurable substrate logic: chemical stability, physical performance, cleaner processing, and export-grade discipline.
EC
< 0.5
mS/cm
Properly washed and treated to support cleaner substrate behavior in controlled growing systems.
pH
5.8–6.5
Stabilized for a more reliable root-zone environment across professional applications.
CEC
High
Supports nutrient retention and stronger uptake efficiency under intensive cultivation conditions.
K / Na Salts
Minimal
Managed to reduce salt-related stress in hydroponics and greenhouse use cases.
Purity
Clean Processed Material
Processed to remove major impurities, contaminants, pests, and disease risks.
Heavy Metals / Residues
Negligible
Heavy metal and pesticide residue exposure is kept at minimal levels.
Physical Performance
Professional growing performance depends on more than chemistry. Structure, drainage, air ratio, and texture stability all shape root-zone behavior.
Process Discipline
Pham Le Group positions quality as a process outcome: direct source control, strict washing and treatment, transparent manufacturing flow, and consistency-oriented handling from raw material to final packaging.
