Mica-Grow - Vermiculite Soil Additive - Brochure

Mica-Grow Vermiculite Soil Additive is a natural mineral which expands under extreme heat with a golden color that resembles mica. The expanded vermiculite mineral can soak up over three times its volume in water and is a natural `wicking` mineral, meaning it acts as a magnet for nutrients like potassium, calcium and magnesium. Because of this, it can be very useful in a passive hydroponics system that does not utilize pumps or other devices to force the nutrient solution to flow.
