Vermiculite
Vermiculite is a natural mineral material that's widely used in vertical farming and indoor growing operations. When heated, it expands into light, spongy flakes that are excellent for plant growing. Farmers and growers value it because it helps hold water and nutrients while keeping soil light and airy, which is crucial for healthy plant growth. It's similar to other growing mediums like perlite or coconut coir. These materials are essential in modern farming methods, especially in vertical farms where traditional soil isn't practical. You might see it referred to as a "soil amendment" or "growing medium" in job descriptions and resumes.
