Quality Control

Multi-point testing, batch-level traceability, and in-house laboratory analysis. Quality is not a department — it is the process.

Manufacturing Discipline, Not Marketing Claims

Growing media quality is defined by measurable physical and chemical parameters — not brand names. Our process is designed to produce substrates with consistent, verifiable specifications. We test. We document. We trace.

What We Test

Parameter Method Target
Electrical Conductivity (EC) 1:1.5 extraction method < 0.5 mS/cm (standard)
pH 1:1.5 extraction method 5.5 – 6.5
Moisture Content Oven-dry method 15-20% (compressed)
Expansion Ratio Volume measurement 5:1 minimum (5kg blocks)
Particle Size Distribution Sieve analysis Per product type
Water Holding Capacity Gravimetric method > 600% by weight
Air-Filled Porosity Volume displacement 10-30% (varies by blend)
Wettability Re-hydration time test < 30 min to full saturation

Consistent EC & pH

Electrical conductivity and pH are the two parameters that determine whether a cocopeat substrate will help or harm your crop.

The Problem with Untreated Cocopeat

Raw coir pith contains sodium (Na⁺), potassium (K⁺), and chloride (Cl⁻) ions from seawater exposure during coconut processing. Untreated cocopeat can have EC levels of 2.0+ mS/cm — toxic for most crops.

Our Result

EC consistently below 0.5 mS/cm. pH stabilized at 5.5–6.5. Every batch tested before packaging.

Fresh Water WashingRemoves loose salts and fine particles

Calcium Nitrate BufferingDisplaces Na⁺ / K⁺ from exchange sites

Final RinseRemoves residual buffer solution
4
Controlled DryingPrevents salt re-concentration

Why Buffering Matters

Washing alone does not solve the salt problem. Cocopeat has a high cation exchange capacity (CEC) — it holds onto sodium and potassium ions even after washing. These ions are then slowly released into the root zone during irrigation.

Buffering with calcium nitrate replaces sodium/potassium ions with calcium ions on the coir's exchange sites. This prevents delayed salt release and provides a stable, low-EC growing environment from the first day of use.

Our buffering process is not optional — it is standard on all export-grade cocopeat products.

Batch-Level Traceability

Every production batch is coded with complete manufacturing data:

  • Date of manufacture
  • Raw material source lot
  • Washing/buffering batch reference
  • QC test results (EC, pH, moisture, expansion)
  • Packing date and line

This traceability system ensures any quality issue can be traced back to its source — raw material lot, processing stage, and responsible operator.
