Pumice Stone (1/8″1/2″)

Aeration Drainage Long-Term Soil Structure

Pumice is a naturally occurring, lightweight volcanic stone formed when molten lava rapidly cools and depressurizescreating a porous structure filled with tiny air pockets. This mined volcanic material is a durable, mineral-rich amendment that improves drainage, aeration, and soil structure in both indoor and outdoor growing environments.

Unlike perlite, pumice is heavier and wont float to the top of your pots, making it a long-lasting alternative for growers who want better moisture balance and microbial support.

Benefits

  • Improves drainage while retaining small amounts of moisture

  • Supports airflow around roots and prevents compaction

  • Offers space for beneficial microbes and fungal networks like mycorrhizae

  • Heavier than perlitestays evenly distributed in the mix

  • Neutral pH, inert, and will not break down over time

  • Builds long-term structure in garden beds or container soil

How to Use

  • Soil Mixes Blend into potting mixes or garden beds at 1040% by volume to increase porosity and reduce compaction

  • Long-Term Use Ideal for living soil systems where structural amendments are needed that wont degrade
