vermiculite

Heat-puffed garden addite

Vermiculite is a mineral that expands dramatically when heated, forming lightweight, accordion-like granules.

The expanded material excels at retaining moisture and insulating against heat, making it valuable in gardening soil mixes, construction insulation, and fireproofing: Mix vermiculite into the potting soil to improve drainage.

It resembles perlite but holds more water.
