Pumice stone (pumice) 5-12 mm

Pumice stone is used mixed with soil to increase the water absorption capacity and aeration of the substrate, which provides plants with access to water for a longer period, ensuring very good drainage.
Pumice (Pumice stone) is a natural substrate derived from volcanic rock. It forms from lava, rich in gases, solidified in water.

Note: Bulk product - packaging is done in zip bags by our staff. Some differences in volume or a margin of error due to porosity, compaction, moisture, or material density may occur, but these variations are considered normal.

Note for international orders: Adding soil products to international orders will increase your shipping costs due to extra weight charges. For each piece you will need to pay an extra cost of 10 Ron (~2 Eur).
