Our Clean-Bag Promise

We want you to succeed, and we’re here to support you throughout your grow. Every Simple Substrate product is carefully prepared, sealed, and inspected before shipping.

If Something Arrives Wrong

If your order arrives damaged, improperly sealed, or visibly contaminated, please contact us with your order number and clear photos.

• Shipping damage should be reported within 48 hours of delivery.

• Sterilized grain must remain unopened and uninoculated for contamination claims.

• Please keep the product until we finish reviewing your claim.

If we determine that the product arrived defective, we’ll work with you to make it right through a replacement or store credit.

After Inoculation

Once grain has been inoculated, opened, or otherwise used, we can no longer guarantee the outcome. Genetics, inoculation technique, cleanliness, storage, temperature, and growing conditions can all affect success and are outside our control.

That doesn’t mean you’re on your own. If you experience a problem, contact us with photos and details. We’ll help you troubleshoot, identify what may have happened, and improve your chances of success moving forward.

Our promise is to provide quality products and real support. Your responsibility is to follow clean procedures, use reputable genetics, and provide the proper growing conditions.

All products are sold exclusively for lawful mushroom cultivation.
