Grain Spawn for mushrooms

Only the Highest Quality, Food Grade Organic Grain

We choose to use human food grade grain in our spawn bags instead of animal feed like many of our competitors. We know you plan to eat the mushrooms you grow and animal feed has far less regulations on what can be sprayed on it.

Attention To Detail Sets Us Apart From The Rest

We hydrate our grain in large batches, by hand, to insure consistency from bag to bag. We hydrate the grain to the ideal moisture content while avoiding burst grains and residual moisture.
