This substrate mix combines coconut coir and vermiculite in a balanced ratio, allowing mycelium to develop evenly and in a controlled manner.

What is this substrate mix?

This substrate mix is a growing medium for mushroom cultivation and consists of coconut coir and vermiculite. The combination provides an airy structure, good moisture retention, and a stable environment in which mycelium can optimally expand.

Because the substrate is sterilized in advance, the risk of contamination is significantly reduced. This makes the mix particularly suitable for both beginner and experienced growers.

How does the substrate work?

After adding colonized grain spawn, the mycelium grows throughout the substrate. The coconut coir retains moisture, while vermiculite provides airiness and structure. Together, they create a climate in which the mycelium can spread quickly and evenly.

The built-in microfilter (5.0 μm) ensures controlled gas exchange while blocking unwanted external influences.
