— Vermiculite is a mica-like mineral that serves as a soil amendment. It is mined out of the ground, exfoliated, and treated with extreme heat and pressure. The resulting worm-like, curly, and sterile product can expand. The silvery-gray and flaky material is so light that the small particles move when you blow on them.
