Where can you find zonolite?

Zonolite, a type of vermiculite, can typically be found in commercial garden supply stores, as it is often used for soil amendments and insulation. Additionally, it may be available at home improvement retailers and online marketplaces. It's important to note that some sources of vermiculite, particularly those from certain mines, have been associated with asbestos contamination, so be sure to check the product’s safety information before use.
