What are the typical physical and chemical baselines (pH/EC) of your expanded minerals?

Because our minerals undergo high-temperature thermal expansion (exceeding 900°C–1150°C), they emerge completely sterile and free of organic matter, pathogens, or weed seeds.

• Expanded Clay: Inert, stable pH(6-7), and ultra-low Electrical Conductivity (EC ≤ 0.5 mS/cm)

• Perlite: Neutral and chemically unreactive, with a pH range of 6.5–7.5. Improves drainage and root-zone aeration without altering nutrient availability.

• Vermiculite: Highly stable with excellent cation exchange capacity (CEC), making it effective for nutrient retention and buffering. Helps maintain moisture and nutrient availability in the growing medium.
