Because the rock is naturally porous, it strikes that elusive balance of allowing excess water to escape while still holding onto enough moisture for acid-loving plants to thrive.

Because it is hand-picked from sustainable swamps and air-dried without additives, it provides that essential soil-like structure that helps delicate new roots thrive. I noticed a slight earthy scent and some water discoloration during the hydration process, but that is simply a sign of its minimally processed, natural state. It works beautifully for everything from making moss poles to creating habitats for reptiles.
