Buyers from a leading New Zealand supermarket chain recognize quality produce when they see it, which is why many major commercial horticulture growers use Pacific Pumice®. The end result, grown in bacteria free pumice with a neutral pH, means the stable chemical structure of Pacific Pumice® provides a superior marketable product.
Pacific Pumice® is a light siliceous vesicular volcanic rock that is suitable for use in horticulture and hydroponics. Its porosity provides plenty of 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 water-holding capacity of the growing medium. This porosity allows free drainage minimising the risk of root rot diseases.
