Medium/Large Caliber Pumice (7/25 mm)


🌍 A natural substrate, sorted and cleaned for excellence

Medium/large caliber 7/25 mm pumice is a 100% natural volcanic rock, extracted mainly from Italian and Mediterranean quarries. At Green and White Plants, we offer you carefully sorted and cleaned pumice , free of dust and impurities. This treatment guarantees an ideal structure to offer your tropical plants a healthy, aerated and durable substrate.

Used for centuries for its exceptional draining properties, pumice has become a must-have in tropical and bonsai cultivation.


🍃 Porous grains for a living substrate

Medium/large size pumice (7/25 mm) comes in the form of light, porous and irregular grains , white to light gray in color. Each fragment acts like a micro-sponge: it stores water while allowing rapid drainage. This perfect texture stimulates root growth by providing aeration, controlled humidity and stability in pots.
