Chunky pumice 8–16 mm: a coarse mineral component

• Porous volcanic rock

Product details

How to use it

A proportion of 10 to 30 % by volume is suggested to lighten a mix, or it can be used alone in certain mineral growing methods for cacti and succulents. Adapt the dose, container and watering to the type of plant.

This coarse grade is not the most obvious choice for small pots with fine roots. Compare 4–8 mm pumice for those uses. A layer of mineral particles does not replace drainage management.
