The UK's longest running magic spore specialist, born in 2017.
- Spore products go out same day when ordered and paid for before 1PM, grow kits same or next day.
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!

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.
Panaeolus cyanescens
TTBVI
The wild Caribbean Blue Meanie. A British Virgin Islands locality line of Panaeolus cyanescens with a tamarind-tree origin story and a big potency reputation. For spore microscopy only.

£10.00
3% Hydrogen Peroxide (1L)
A 1 litre bottle of 3% hydrogen peroxide (10 volume) for spot-treating early cobweb mould and sanitising tools and work surfaces. It breaks down to water and oxygen and leaves no residue.
£10.00
3M Breathable Micropore Tape
Genuine 3M Micropore paper tape, 1.25cm by 9.1m. A breathable, latex-free seal for inoculation points, plate edges and lid holes that lets air and water vapour through while keeping out larger airborne dust and debris.

SporeKit™ 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.
Perfect your sterile technique and grow cleaner flushes. Shop SporeKit →
Agar (for gourmet spore swabs)
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.
Grain (gourmet spore syringes/swabs/prints)
1 / 16
In stock now
Newly stocked.
Still-Air Box (Lids to size)

Price range: £10.00 through £20.00
PF-Tek MycoBox Grow Kit
Our original kit, the classic PF-Tek cake brought up to date. You inject one sterile brown-rice cake through a single port, let it colonise, then dunk and fruit it in the included tent. Hands-on, and the friendliest place to start.

Spore and grow-kit basics.
Are your spore products legal to buy?
Yes. In the UK it is legal to possess and sell Psilocybe mushroom spores for the purpose of microscopy and collection, because the spores themselves contain no psilocybin or psilocin. Germinating and cultivating them is illegal and not what we sell them for. All our magic-species products are sold strictly for research, microscopy, and collection.
What's the difference between spore syringes and liquid culture?
A spore syringe contains dormant spores in sterile water, intended for microscopy. A liquid culture contains live, actively growing mycelium in a nutrient broth, used for cultivating legal gourmet species and giving you faster, more reliable colonisation than starting from spore.
What does ISO4 actually mean?
It's the cleanliness classification of our laminar flow hood. ISO4 is one tier stricter than ISO5, with fewer than 10,000 particles ≥0.1 µm per cubic metre of air. Every syringe is pulled under that hood, every time.
How long does shipping take?
It comes in two parts: how quickly we dispatch, then how long the courier takes. Dispatch time varies by product and is shown on each product page (spores go out faster than made-to-order grow kits). Once dispatched, most UK orders arrive within 1-3 working days on tracked Royal Mail, and worldwide delivery is typically 5-15 working days depending on the service you pick. Your exact dispatch date and delivery estimate are shown at checkout for your address before you pay.
Is shipping discreet?
Yes. Plain packaging, no branding, no give-away of contents. Tracked Royal Mail UK-wide.
What's the difference between MonoBox and MycoBox?
MonoBox is the simple all-in-one (just inject and wait), our customer favourite. MycoBox is the original injectable design we pioneered. MycMonster™ XL is the brand-new oversized variant for big yields. All three accept the same syringes.
What if my spores look wrong under the microscope?
We guarantee our spores are viable and clean for microscopy purposes. If you see anything unexpected, contact us within 6 weeks of dispatch with your order number and we'll replace the syringe.
What if you don't stock the strain I want?
If there are any magic spores we don't have, let us know and we'll put an order in. Our catalogue is driven by what customers actually ask for. Drop a request and we'll source it.
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.
Warning fur wit yer 'bout tae see,
for a habitual nail biter are thee.
I'm intentionally doing the following procedure with bare hands to prove a point, that a 'risky' procedure can be done with without worry if you're a careful. Just ignore the £7K flowhood in the background and imagine I'm working inside plastic SAB!
(I really should have done this in a SAB, in retrospect...!)
