Return Policy

Return Policy

Our Clean-or-Replace Guarantee

We stand behind every culture we ship. If your order arrives contaminated, damaged, or non-viable, we will replace it or refund you in full — no questions asked. This is our promise to every customer.

Biological Materials

Due to the sensitive nature of our products (liquid cultures, substrates, grain bags, and other biological materials), we cannot accept returns on opened or used items. This policy protects the integrity and safety of all products.

Damaged or Contaminated Products

If your order arrives damaged, contaminated, or shows signs of compromised packaging, please contact us within 7 days of delivery at support@flyingmushroom.com with:

  • Your order number
  • Photos of the damaged or contaminated product
  • A brief description of the issue

We will arrange for a free replacement or full refund at no cost to you.

Incorrect Orders

If you received the wrong item, please contact us within 7 days and we will send the correct product at no additional charge. You keep the incorrect item.

Refunds

Approved refunds will be processed within 5-7 business days to the original payment method.
