Natural small diatomite rocks, helping improving drainage and reducing roots rot. One of the best soil rocks for terrarium.

It is porous, allowing good drainage. After spraying water, the small rocks will become a little sticky and will stay in place.

This soil is made in the shape of small rocks. In a moss terrarium, you can use gardening soil instead of it. But this is the most neat one I ever used.

The layers of a terrarium from bottom up: small lava rocks (or any other porous rocks) < sphagna (for absorbing water) < soil (this diatomite rocks or other soil in your hand).

Good for potted plants, jar, terrariums, best home decor, DIY projects and fairy gardening.
Ideal for various plants, like moss, succulents.
