No, grain spawn is not an all-in-one kit and cannot be used to fruit mushrooms out of the bag. Grain spawn must be mixed with bulk substrate before you can fruit it.

Grain spawn can be used in a wide variety of ways including indoor growing, outdoor growing, or to make more grain spawn. (Grain spawn can be used to make plug or sawdust spawn, not just other grain spawn.)

• Indoors, you can mix grain spawn with bulk substrate to grow in bags, in containers, or to create fruiting cakes.
• Outdoors, you can mix grain spawn with straw or wood chips to make beds and containers. (Note: Grain spawn can not be used for logs.)
• A grain-to-grain transfer allows you to extend the life of your grain and create more grain spawn.

Our grain spawn is a proprietary blend that features nutrient-rich organic millet and wheat berries.
