It has a clay-like and soft texture, unlike pumice, which is a hard rock. Comparing the properties of these two minerals, pumice has more porosity and, therefore, a better drainage potential. But vermiculite is far superior in retaining moisture compared to pumice soil. Both of them have different purposes in horticulture.

Vermiculite finds its way into many seed starting systems. It protects seedlings from fungus that often ruins seed starting and helps retain water in the cell trays that seeds start in. While perlite can be used with seedlings, it's better when you move your seedlings into separate pots for additional drainage.
