Price changes, and more on the way.

We've dropped our prices. Every Cubensis spore syringe is cheaper, and grow kits too:

  • 1ml syringe £3 (down from £5)
  • 3ml syringe £6 (down from £8)
  • 12ml syringe £12 (down from £16)
  • MycoBox grow kit £28 (down from £38)
  • MonoBox grow kit £32 (down from £45)

These newer, lower prices are temporary.

New: for the first time, we now offer a 12 week EZ-Warranty on grow kits, which you can add at checkout for £10 on a MycoBox and £13 on a MonoBox if you want.

Notice we also dropped the prices of grow kits by about the same, so essentially we now cover 12 week free replacements (in the unlikely event something goes wrong with a kit). You were already covered for issues being our fault, but now we offer warranty that covers you guys being at fault too.

It also felt fair to backdate this to cover all customers who've paid the old price for kits over the past 12 weeks.

Why have we added this? Because it feels human.

How do you replace a kit? Head to the replacement portal, select the problem kit in your order, and it drops into your basket for £0.

Are we always going to have this available? If it goes over a certain threshold we have, then we'll maybe have to reconsider it.

How EZ-Warranty works, in full →

We also have a couple of promos going right now on Tidal Wave and TEX PE6 (max two per order until stocks run out) as we're getting new spore stock this week.

There are still lots of products out of stock right now as well as incomplete (or badly worded) pages... we're getting there. Admittedly, we've had to use quite a bit of AI to write the copy on quite a few pages, so the main plan is to get all that stripped out before our September deadline we've set ourselves. AI written slop doesn't belong on Cylocybe, our bad grammar is at least human.

We're about to launch a couple more grow kits as well as an improved CyLab and other useful grow equipment.

Stay tuned!

Exotics & rare species

Beyond cubensis:
EXOTICS.

We also carry many more species for the serious connoisseur, like Pan. cyanescens (MIB and TTBVI), Psilocybe azurescens (the flying saucer), Psilocybe cyanescens (the wavy cap), sclerotia / truffle spores like Psilocybe mexicana and P. tampanensis, and much more. Please bear in mind that many of our exotic species are wild-foraged and printed, and so could have the odd hitchhiker, unlike our P. cubensis, which are legally lab-cultivated and printed for ultimate cleanliness.

SporeKit grain spore testing kit jar

SporeKitโ„ข Testing Kit

Test your spores
before risking your grow.

Gourmet spore syringe producers can't test every syringe they sell. If they claim otherwise, they're full of it. A few pounds for a SporeKit gives you the means to verify your own spores before risking your substrate.

Choose between Grain (for syringes) or Agar (for swabs). And here's the clever bit: successful tests double as live culture syringes. The mycelium that grows out from a clean test can be injected directly into a grow kit.

Price range: £4.00 through £14.00

Perfect your sterile technique and grow cleaner flushes. Shop SporeKit โ†’

Agar (for gourmet spore swabs)

SporeKit in use

Please note; the following pictures show live agar culture being produced with the assistance of a laminar flow hood, you aaaabsolutely do not need one in this hobby to achieve 90-95% success rates - a cheap plastic Ikea tub with arm-holes cut in it will do you just fine (aka Still-air Box / SAB).

We now sell lids with laser-cut arm-holes so you can attach them to 'Samla' tubs from Ikea.

Reviews

What customers say.

Unfortunately we lost thousands of reviews which dated back to the beginning days of Cylocybe, after Trustpilot cancelled us for being a "bad-fit" for them in 2021. We blogged about it. If anyone can recover those reviews in full somehow, we’ll send you an All American 41.5 Quart Electric Steriliser (like we did for the 2000th Trustpilot reviewer!).

★★★★★
The guides are very well made and the grow kits are made so that you actually understand each stage of the growing process and learn how mycelium actually works. It can take you from 0 to an experienced and knowledgeable grower.

A great place to start if you're interested in growing your own medicinal or gourmet mushrooms. Works every time.
