Green Spade Vermiculite 5L

Green Spade Vermiculite is a mica-like special mineral (Iron magnesium aluminum silicate), which expands around 15 times in volume by popping effect when heated to 870°C (1,600°F). The result of expansion enhances the substance’s moisture absorption and water retention capabilities as well as allows free air passage i.e. the vital aeration to the roots of the plant.
