Sourced from our local Jemez Mountains, pumice is a volcanic material which makes a great addition to many media mixes, capable to taking the place of perlite with the advantage that it doesn’t float or blow away. It is also much more resistant to being crushed than perlite. We also use it extensively as a stand-alone media for Mexican Pinguicula.
14 liters is approximately 20 pounds of pumice and fills a USPS Large Flat Rate Box.
1:1 ratio with akadama or long-fiber sphagnum is a good mix for Nepenthes.
1:1 with peat is a good mix for Heliamphora.
