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 water-holding capacity of the growing medium.
Specifications:
- Size – 1 to 7mm
- Volume – 25 litres
- Weight – 24kg
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 light weight in comparison to competing aggregates. The washing and screening of our pumice particularly for horticultural applications means that no “fine” particles are included. Unwashed pumice can cause “concreting” and higher water holding capacity than required, consequently effecting root development.
This hardness and porosity allows free drainage lowering the risk of root-rot diseases.

This product is as described in the advert. It should be ok for the intended purpose, which is as a component of a soilless mineral based potting mix for succulent plants, including cacti.
My only negative comment relates to the amount of water that is contained within the bag. I imagine that it is there to minimise dust. But the product is wringing wet. That significantly adds to the weight of the 25 litre bag.

I have used this product for a while and it’s one part of my potting mix , the consistency in size does not vary from bag to bag which is something you don’t find to often in this day and age
So if you if want to use in you soil mix do not hesitate to buy
