Vermiterra Medium - Exfoliated Vermiculite

Versatile soil conditioner with excellent nutrient retention.

Vermiterra

Vermiterra Medium is a hydrous phyllosilicate mineral belonging to the clay group with lamellar structure. When heated to 900°C, the trapped water vaporizes, causing expansion up to 30 times the original volume. The exfoliation creates lightweight accordion-shaped granules with larger particle size ideal for soil mixing and conditioning.
