Product Description
To successfully grow mushrooms in your bag or tubs, we recommend a minimum 3:1 ratio of Coir & Vermiculite substrate to Rye Grain Spawn. This combination ensures that once fully colonised, the grain spawn will provide all the necessary nutrients, while the substrate effectively retains the moisture required for fruiting.
Our grain spawn is fully hydrated and nutrient-rich, and the coco coir and vermiculite are prepared to field capacity. Both products are sterilised in a vertical steam pressure autoclave for 3 hours at 15 PSI. The ratio of spawn to bulk can be increased if the mushroom is prone to blobbing. This hassle-free recipe offers a ready-made solution for your mushroom growing needs.
