Pumice Horticultural Grit. Kiln dried and exceptionally light weight. The industry standard for cacti and succulent compost mixes.


Pack size: 8kg (Approx 16 ltrs)

Particle Size: Nominal 2-4mm (for typical grading limits see below)

Description and Use: An exceptionally light weight and thermally insulating, natural micro-vesicular (bubbly) pumice grit. When incorporated into compost mixes the open honeycomb structure of the pumice allows for absorption of moisture which is slowly released as the compost dries out

Seeds & Cuttings:
Pumice Horticultural Grit is both sterile and pH neutral making it an ideal moisture retaining compost component when planting seeds and cuttings. Its open honeycomb structure and low density ensures that it warms up more quickly than conventional stone based grits and also provides insulation aiding germination and protection of vulnerable seedlings.

Terrariums, bottle gardens and Vivariums :
Use as a moisture retentive gravel substrate and soil conditioner when planting both open glass containers and closed terrariums.
In the base of vivariums, use in place of plastic bead or heavy gravel substrate.
