Returns & Refunds
Due to the perishable and biological nature of many mushroom growing products, once grow kits, cultures and substrate products are opened or exposed to air they can no longer be resold or reused, thus we cannot accept returns on those items unless they arrived faulty or damaged. This policy helps protect both product quality and customer safety.

Returns
At MGS we are more than happy to facilitate the return of orders and products for up to 14 days following their receipt, as long as the item(s) are unopened where perishable, and in the same condition they were in when they first arrived with you.
Products that cannot be returned:
- Grow kits that have been exposed (opened) to air
- Grow boxes that have been cut open
- Liquid cultures that have been unsealed / injected
- Substrates that have been opened
- Anything damaged or unable to be resold

Refunds
Once a return has been accepted and received, we'll provide you with a full refund within 14 days of the item(s) reaching us. Refunds will be issued to the original payment method used at checkout and can take 3-10 working days to appear in your bank account, depending on your bank or payment provider.
Gift card refunds will be returned as store credit.
Refund notes:
- Original delivery costs are non-refundable unless the item is faulty or incorrect.
- Partial refunds may be issued where only part of an order is returned or where items are returned incomplete.
- Refunds cannot be issued for items that do not meet the return conditions outlined above.
This policy operates in line with UK consumer protection standards.
