Pumice is a dry amendment known for it's amazing soil aeration abilities. Perfect to add to premium potting mix at a 1:1 ratio for cacti planting. It is also an alternative to perlite within blended potting mix due to its high cation-exchange capability (it absorbs nutrients and water and release them into the surrounding soil as required).
Pumice can also be used as an alternative to pumice or LECA for hydroculture propagation. We advise to rinse thoroughly prior to use in soilless growing.
Available in 1kg bags.
