Vermiculite
1 Liter Vermiculite, In the past, we've received a lot of requests from people, where to get vermiculite. It's mainly used in the packaging-industry and also used by agro-companies. Most companies are only selling bulk. If you're lucky, you may find it at some garden-centers. If not, we can supply you with it.
Vermiculite is puffed rock, which is very light. Like perlite. The airy structure supplies room inside substrate mixtures for the mycelium to 'breath'.
We have one liter bags, containing vermiculite (0.3), ideal for the Magic Mushroom Grower.
