Premium Horticultural Pumice, graded 4-20mm, in 8.3 litre bags. Sourced from New Zealand, this natural volcanic rock is lightweight and highly porous, providing superior aeration and drainage in growing media. It retains moisture without waterlogging, supports root development, and resists compaction. Chemically inert and pH neutral, it suits mixes for cacti, succulents, orchids, carnivorous plants, and bonsai. Apply as a soil amendment to enhance structure, as top dressing to reduce evaporation and suppress weeds, or in hydroponics for stable, sterile substrate.
