3lb Sterilized Grain

• 1 × 3 lb sterilized whole-oat grain bag
• 2 × 4 lb pasteurized CVG substrate bags
• 11 lbs of prepared growing media

Genetics and monotub are not included.

• A legal mushroom liquid culture or spore syringe
• Isopropyl alcohol
• Clean gloves
• A clean workspace
• A bag sealer or another suitable way to securely close the bags when growing in them, such as rubber bands or binder clips.
• A suitable monotub if using the monotub method

1. Clean your workspace, hands, grain bag, and inoculation equipment.
2. Follow the sterile-handling instructions provided with your legal mushroom culture or syringe.
3. Introduce the mushroom culture into the sterilized grain bag.
4. Store the bag under conditions appropriate for your mushroom species.
5. Allow the grain to colonize completely before combining it with the CVG substrate.

Colonization time varies depending on the mushroom genetics and growing conditions.

1. Divide the fully colonized grain evenly between the two CVG bags.
2. Mix the grain thoroughly throughout the substrate.
3. Securely close the bags and allow the substrate to colonize.
4. Once fully colonized, introduce fruiting conditions appropriate for your mushroom species.
5. Monitor growth and harvest at the proper stage.

Growing in the bags is a simple, contained option that requires less additional equipment.

1. Clean your monotub and workspace.
2. Break up the fully colonized grain.
3. Combine the grain with both CVG substrate bags inside the monotub.
4. Mix evenly and level the surface without heavily compacting it.
5. Allow the substrate to colonize before introducing fruiting conditions appropriate for your mushroom species.
6. Monitor growth and harvest at the proper stage.

A monotub provides a larger growing surface but requires additional equipment and environmental control.

For best results, use your grain and substrate as soon as possible after delivery.

Store unopened bags in a clean, cool area away from direct sunlight and excessive heat. Always inspect bags before use.

Every bag is carefully prepared, sealed and inspected before shipping. If something arrives damaged or visibly contaminated, contact us and we’ll work with you to make it right.

Once a bag has been opened or inoculated, results cannot be guaranteed but you’re never without support. We’ll still help you troubleshoot and understand what may have happened.
