Organic Masters Mix Bulk Substrate
Considered the holy grail of substrates, perfect for so many gourmet fungi.
This substrate colonises quickly and due to high nutritional content produces a larger first flush.
Our organic soy hulls are a byproduct of tempeh production from the lovely people at Club Cultured.
Masters Mix was formulated by TR Davis at Earth Angel Mushrooms in the USA and Is now in use across most western mushroom farms.
