Sourced from exfoliated volcanic rock, it is 100% natural, inert, and will not decay or develop mould — two properties that matter significantly when eggs are spending weeks or months in an enclosed environment.\u003c\/p\u003e\u003ch3\u003eWhat it is\u003c\/h3\u003e\u003cp\u003eVermiculite is a naturally occurring mineral that has been heat-expanded to create a lightweight, moisture-retentive medium. Because it is inert, it introduces no organic material that could break down or harbour pathogens during incubation. The coarse grade provides good air circulation around eggs while still holding the humidity levels most species require.\u003c\/p\u003e\u003ch3\u003eSetting up for incubation\u003c\/h3\u003e\u003cp\u003ePlace a generous layer of moistened vermiculite into your incubation container before adding eggs. As a starting point, a 2:1 ratio of vermiculite to water by weight suits many species — though individual species requirements vary and should be researched before eggs are laid. Eggs should be positioned with the top third exposed above the surface, and kept the same orientation as they were found at the laying site. Where possible, prevent eggs from making contact with one another during the incubation period.\u003c\/p\u003e\u003ch3\u003eA note on incubation\u003c\/h3\u003e\u003cp\u003eReptile egg incubation is a species-specific process with significant variation in humidity, temperature, and duration requirements. It is essential to research the exact needs of your species well in advance, and to have a suitable incubator set up and running before eggs are laid.
