Advantages of Pumice for Ponics Systems
Our pure pumice grow media provides a combination of benefits to high-efficiency growth ecosystems that no other media can:
Ponics Stone™ grow media is pH neutral.
Our natural pumice grow media provides an ideal balance between drainability, moisture retention and gas exchange in the root zone.
The porous structure of Ponics Stone™ grow media is an ideal environment for bacteria / microbe colonization.
The finely-riven surface of the Ponics Stone™ pumice stones are easy on both hands and roots, allowing shock-free transplanting.
No rinsing required—the clean, fine dust packaged with the grow media will readily disperse, delivering a quick nutrient charge to the system.
Pumice is the physiochemical twin of perlite, without the expense and energy-burn needed to expand perlite to its useful-foamed nature.
