Increase the yield of your home-made fruiting blocks!
Our premium sterilized ‘Mastr Mix’ contains a blend of hardwood sawdust, non-GMO soyhulls, and select substrate amendments. This proprietary blend is formulated for higher yields and has a pleasant, leafy, deep veggie aroma (thanks to the premium soyhulls used in our recipe).
After more than a year of development, the result is a product with a better nutritional profile for a faster mycelial run (and even better yields than the original mix mushroom growers have come to love!) ‘Mastr Mix’ is an ideal bulk substrate for use with any of our grain spawn strains.
This bulk substrate is ideal for fruiting straight from the bag in a controlled environment (like a martha tent or monotub).
Moisture content: Each bag is optimally hydrated for fast colonization times and top yields.
How to use:
- For 3 lb. bag of inoculated grain spawn - we recommend 8-12 bags of Mastr Mix
- For 6 lb. bag of inoculated grain spawn - we recommend 16-24 bags of Mastr Mix
