Product details
Horticultural Pumice
Pumice is a light siliceous vesicular volcanic rock that is suitable for use in horticulture and hydroponics. Its porosity provides air spaces that maintain aerobic conditions around the roots while water is contained within the pores. Surface tension around the outside of the pumice particles increases the water-holding capacity of the growing medium.
Our pumice is mined from a land-based resource, within 50kms of Lake Taupo in the North Island of New Zealand, and it is characterized by its relative hardness and lightweight in comparison to competing aggregates. The washing and screening of our pumice particularly for horticultural applications mean that no “fine” particles are included. Unwashed pumice can cause “concreting” and higher water holding capacity than required, consequently affecting root development.
This hardness and porosity allow free drainage, lowering the risk of root-rot diseases.
Pumice grade: 1-2mm, 1-7mm or 7-20mm
