It’s finally in. Well, the beginning stages anyway. Jar substrate. Anyone who knows anything about snails knows that they can’t live in a glass box without some sort of substrate to hide in, get moisture from, and burrow under. So now you can apply one type of substrate (so far) to a jar. Eventually there will be different kinds of substrate, and maybe even substrate you can mix together from other types of substrate. Currently the substrate has no effect on the snails or the environment outside of being present and visually represented, but eventually it can impact everything from snail nutrients to jar temperature and what kinds of plants you can grow inside the jar. Here’s how it works.
