Our proprietary blend of mushroom growing substrate for wood loving species is comprised of oak sawdust, soy hulls, and other micronutrients. It is pre mixed, pre-wetted to field capacity, and sterilized in unicorn XLS-T bags.
Over several years, it has been perfected for wood loving mushroom species to increase your yield, and is widely-trusted by mushroom growers.
Note: Substrate is hydrated to field capacity.
Use our substrate in filter bags, outdoor beds, grow trays, grow tubs, or shoe boxes in a humidity-controlled grow room (or Martha set up).
We recommend a 3 to 1 ration of inoculated grain to bulk substrate.
Each bag is 5 lbs.
Perishable, inoculate as soon as possible after receiving.
