HollandBasics Ultra Premium Pumice is top grade pumice mined from chilled North American volcanic deposits. Our pumice contains ultra porous texture allowing oxygen, water and nutrients to naturally travel throughout plant root systems and maintaining a reserve of nutrients stored in microscopic holes. Succulent and cacti can greatly benefit from our ultra-premium pumice for increasing water retention in sandy or clay soil to allow efficient distribution of nutrients and liquid.
Pumice prevent erosion to the soil as it protects roots from surface exposure. the pH of pumice is neutral neither alkaline or acidic which is ideal for any type of plants or growing conditions.
