Perlite
Perlite is a lightweight, white volcanic material used widely in gardening and plant care. When processed, it looks like small white pebbles or bits of styrofoam. Gardeners and horticulturists use it to improve soil quality by making it lighter and helping with drainage. It's often mixed into potting soils and growing media. Think of it as tiny sponges that hold just the right amount of water while keeping air spaces for plant roots. Similar materials include vermiculite or pumice, but perlite is particularly valued for its excellent drainage properties and long-lasting nature.
