Returns & Refunds.

1. Changed your mind? Your 14-day cancellation right

If you have simply changed your mind, you can cancel your order within 14 days of the day it arrives. Just contact us to let us know.

If you cancel, two things apply. You cover the cost of posting the items back, and you need to send them back within 14 calendar days of telling us. Once we have received the return, we will process your refund.

2. Replacements, by product

What we can do depends on the product, so here is each one in plain terms. Find yours below.

Mushroom Grow Kits

Grow kits cannot be replaced or refunded once they have been used. They are perishable and cannot be resold, so please check yours over before you start. If you spot a problem before using it, contact us straight away.

We do not offer refunds on grow kits. In exceptional cases we may offer a replacement, at our discretion. If your kit arrives damaged or is not what you ordered, see Section 3 and get in touch within 72 hours of delivery.

SporeKit (bought on its own)

A standalone SporeKit is guaranteed to arrive sterile. If it turns up damaged or contaminated, we will replace it, as long as you tell us before it has been used. Once a SporeKit has been injected with a gourmet spore solution it counts as used, and at that point it is no longer eligible for a replacement.

Liquid Culture Syringes

Liquid culture syringes are for gourmet (edible) mushroom cultivation, and we guarantee they are viable and authentic for that purpose. If you believe yours does not meet that standard, you can request a replacement, at our discretion. Please let us know within 3 weeks (21 days) of the dispatch date. We do not offer refunds on liquid culture syringes.

Psilocybe cubensis Spores (syringes, prints, swabs, vials)

These are sold for microscopy and genetic preservation only, and we guarantee they are authentic and viable for that purpose. If you believe a Psilocybe cubensis spore product does not meet that standard, you can request a replacement, at our discretion. Please tell us within 6 weeks (42 days) of the dispatch date. We do not offer refunds on spore products.

All other spore products

These are also sold for microscopy and genetic preservation only. Many of these species are gathered from the wild, unlike species such as Psilocybe cubensis which are produced in labs and tend to be much cleaner. Wild-sourced spores can carry natural hitchhikers (extra microbes that come along for the ride). Because of that, we offer no replacements, no refunds and no returns on these items.

If the parcel itself arrives damaged, or the items are not what you ordered, that is different. Get in touch within 72 hours of delivery and we will sort it out. Note that the spore products themselves still cannot be sent back to us (see Section 5).

CyLab

A CyLab is guaranteed to arrive unbroken. During manufacturing, small surface marks or hairline cracks can appear around the drill holes. These are cosmetic only and do not affect how it performs.

If the cracking is excessive, making the unit unfit for purpose, and it has not been used, we will sort it out. We can replace the affected part, or offer a partial refund so you can replace that part yourself where that makes sense. If you would rather, we can cover the return and give you a full refund. Please check your CyLab when it arrives and send us a couple of photos before using it, so we can help quickly.

3. Damaged or wrong items

If goods arrive damaged in transit, or are clearly different from what you ordered, we will take a return and give you a full refund on eligible items (the ones not excluded above). Please tell us within 72 hours of receiving the parcel so we can fix it fast.

Spore products and Mushroom Grow Kits are not refundable. Where there is a problem with these, we handle it by replacement or resend, at our discretion, as set out in Section 2. Please do not send spore products or grow kits back unless we have specifically asked you to.

4. How returns and replacements actually work

Before sending anything back, email us with your order number and a short note on what is wrong. Wait for explicit approval from Cylocybe before posting anything, so we can confirm the next steps. Returns and replacements are considered at our discretion.

On who pays for postage:

• Changed your mind? You cover the return postage, as in Section 1.
• Anything else? The customer generally covers shipping costs, unless we confirm otherwise by email.
• Damaged or wrong (Section 3)? Our approval email will tell you whether we are sending a prepaid label or reimbursing reasonable return costs.

Once we have received the goods back and inspected them, we process the refund or replacement using the method we agreed with you.

5. Items we cannot refund or replace

So you know where you stand:

• All spore products (Psilocybe cubensis syringes, prints, swabs and vials, plus all other spore products). No refunds. For safety and quality reasons we do not take returns of spore products.
• Mushroom Grow Kits. No refunds once used. They are perishable and cannot be resold.
• Liquid culture syringes. No refunds. Handled by replacement only, within 3 weeks (21 days) of dispatch and at our discretion, as in Section 2.
• Anything with a broken or removed seal, and any personalised, bespoke or made-to-order product. These are not eligible for a refund or replacement, unless they arrive faulty as described in Section 3.
