Return and Refund Policy

Last Updated: October 27, 2026

At That Mushroom, all products are sold strictly for legal cultivation purposes (such as gourmet, medicinal, decorative, and industrial applications). Any illegal activity, regardless of location, voids any and all warranties associated with our products.

1. Return & Refund Eligibility

  • Return Window: All refund and return requests must be made within 7 days of delivery.

  • General Merchandise & Grow Supplies: Unopened, unused items in their original packaging are eligible for return within the 7-day window. A 20% restocking fee applies to all accepted returns. The customer is responsible for all return shipping costs using tracked shipping. Once the returned item is received and inspected, we will process your return.

  • Pasteurized & Sterilized Products: We do not accept returns on our pasteurized and sterilized products (such as grain and substrate bags) once they have been delivered, as these are perishable items.

2. Contamination & Damage Guarantee

We proudly stand behind our quality with a contamination-free guarantee:

  • Contaminated or Damaged Items: If one of our products arrives contaminated, broken, or damaged during shipping, we will replace the item.

  • Reporting Issues: Physical defects, damages, or contamination claims must be reported within 7 days of delivery. For damaged or contaminated materials, please provide clear photos showing the issue alongside the original packaging and a dated note.

3. Exclusions & Voided Warranties

The 7-day warranty and eligibility for returns or refunds are immediately voided if the product has been used in any way after receipt. This includes:

  • Adding genetic materials, liquids, or cultures

  • Exposing products to excess heat or freezing

  • Modifying, cutting, ripping, puncturing, tearing, or altering injection ports

  • A customer's inability to read product descriptions or properly use products does not qualify an order for a refund.

4. Shipping & Cancellations

  • Order Cancellations: Order cancellations must be requested within 48 hours of purchase.

  • Returned Packages: If a shipment is returned to us due to an incorrect address or delivery failure, a reshipment fee will apply. If the buyer chooses not to pay the reshipment fee, the order will be refunded minus a 20% restocking fee, and original shipping costs will not be refunded.
