Vermiculite

Vermiculite is a natural mineral that expands when heated, resembling small, shiny, light-colored pellets. It's often used in gardening and construction due to its excellent insulation, moisture retention, and aeration properties. In gardening, it improves soil structure, helping plants retain water while allowing air to reach the roots. In construction, it can be found in lightweight concrete and as insulation material. While generally considered safe, some vermiculite can contain asbestos, so it’s important to source it from reputable suppliers. Overall, vermiculite is a versatile material that enhances both agricultural and building applications.
