Best-Selling Spore Syringes & Grow Kits.
These are the products a lot of people go for, the Cylocybe Special MycoBox Grow Kit has sold so many we had to move to an industrial unit to cope with demand!
Microscopy Spores
Psilocybe cubensis spores.
We're all here for the same thing, to check these out under the microscope!
Every spore syringe is made clean with a state of the art ISO4 (better than ISO5) laminar flow hood and with sterile technique developed over 20 years.
And every P. cubensis is available in 12ml/3ml/1ml syringes, 12ml vials, swabs and foil spore prints.
Our microscopy spores are sold for legal microscopy research only. Our grow kits are strictly for culinary or medicinal cultivation. Never mix the two together.
Psilocybe cubensis
Golden Teacher
The mushroom that taught the hobby what a cubensis looks like. Wide golden-caramel caps, a heavy dark print, and a name everyone knows but nobody can quite source.
Psilocybe cubensis
B+
The big, easygoing classic, and the cube that taught half the hobby to focus a microscope. A heavy purple-black spore print and clean, textbook spores.
Psilocybe cubensis
Our Selection
Our house pick of Psilocybe cubensis: a dependable, classic-looking cube chosen for clean, heavy spore drops rather than a famous backstory. A curator's choice labelled.
Psilocybe cubensis varieties stock status.
We are currently awaiting an imminent restock for some of these! If you want reminding when something comes back in stock, go to the product page and click 'Tell me when it's back' and we'll drop you an email.
Spores
Spore syringe production 101.
To get an idea of the attention to detail which kept us UK No. 1 for so many years:
After our syringes are filled with spore solution, they are immediately passed over to a second expert responsible for screwing on the sterile syringe caps, all whilst sitting in front of an ISO4 laminar flow hood (10 times cleaner than the ISO5 flowhoods our competitors use (ouch!) - but probably 10 times more expensive (OUCH).
The capped spore syringes are then quickly sealed in ziplock bags.
Once we finish filling and capping the spore syringes, we clean the stainless steel workspace. Then, one by one, we take each spore syringe and pack it into a laminar-foil, light-blocking bag. We never label within the lab because dirty, sticky labels don't mix well with latex-gloved hands and sitting a printer in front of a laminar flowhood would call for some life choice evaluation!
This all means the syringe itself will never be labelled, keeping it super clean. When the time comes to remove it from the foil bag, you won't cross-contaminate your workspace by handling a syringe with a dirty trich-ridden exterior.
Our labelling is performed on the laminar-foil bag after we exit the the laminar flow hood and lab and we strictly only use labels made from polypropylene so YOU can safely wipe the whole thing down with isopropyl alcohol before taking it into your SAB for that extra caution.
Our entire production process for spore syringes is carefully thought out and designed for the customer's benefit, not our own (and yet, our prices are still amongst the lowest in the UK).
From our YouTube
Preparing a Cylocybe syringe.
Our syringes are fitted with professional tamper-evident luer-locking syringe caps which you may not have seen before (unless you've dealt with a vendor worth their salt). We use these so you know no-one has tampered with them between our lab and your hands.
Here's a quick video we made to show how they are used, notice the way we open a needle (for us, that's faster, cleaner and more practical) - open it how you want!
Playing it here streams from YouTube, they then see you're on our site. Click "Watch on YouTube" if you don't want that.
Not demo'd in the video: The plastic break-off component doubles as a screwdriver so you can remove the red cap without getting your grubby fingers anywhere near the exposed syringe opening!
Exotics & rare species
Rare & Exotic Magic Mushroom Spores.
We also carry many more species for the serious microscopy 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.
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.
Out of stock
Psilocybe Cyanescens
The caramel wood-chip Psilocybe with the undulating cap margin and a purple-brown print, scientifically born in Britain at Kew. A landmark wood-loving species and a rewarding microscopy subject. Sold strictly as a spore specimen for microscopy, taxonomy and collecting.
Out of stock
Psilocybe Semilanceata
The wild British grassland icon and the conserved type species of the entire Psilocybe genus. A tiny sharp-nippled conical cap that you study, print and identify, never farm. Offered strictly as a microscopy and taxonomy reference specimen.
Out of stock
Rare & exotic varieties stock status.
Species like Psilocybe Cyanescens and more will be restocked in the coming days. If you want reminding when something comes back in stock, go to the product page and click 'Tell me when it's back' and we'll drop you an email.
Sclerotia species
Magic truffles.
Sclerotia / truffle spores like Psilocybe mexicana and P. tampanensis.
Psilocybe Mexicana
The mushroom modern psilocybin science actually began with. Roger Heim named it in 1957, grew it in his Paris lab, and from that cultivated material Albert Hofmann isolated the first pure psilocybin.
Psilocybe Tampanensis
The sclerotia-forming Psilocybe behind the "Philosopher's Stone": a sandy-meadow rarity from Florida, known to science from almost a single 1977 find, with small angular spores and a purple-brown print all its own.
Sterile and injectable
Mushroom grow kits,
made easy.
At Cylocybe, our mission (as corny as it sounds) is to make mushroom growing as common as house plants!
Nervous newbie? Don't be... Growing mushrooms is EASY. Our mushroom growing kits come with grow guides, plus we're here to help if you get confused about anything - just ask us.
As well as growing mighty mushrooms with success, you'll be fascinated with every step of the journey. From watching the mycelium take over the mushroom spawn, then into the substrate, to the tiny pinheads that form into big mushrooms, to the caps which stretch open to rain down spores... The full life cycle, from spore to spore. If that doesn't get you excited, you've picked the wrong hobby!
MonoBox Grow Kit
Like a dialled-in 'Monotub' grow without the hassle! Give your mushrooms the humidity and airflow they deserve with our brand-new included Cylo Grow Tent.
PF-Tek MycoPot Grow Kit (DIY)
The original cake method, the hands-on way. You make up and sterilise eight brown-rice cakes yourself, inoculate them with your own gourmet culture, then dunk, roll and fruit them. You finish it understanding every stage of a grow.
MycoBox Grow Kit
The original single-stage kit. You inject your own gourmet culture straight into the sterile substrate box through the ports on the lid, colonise, then dunk and fruit in the included tent. One box, no grain step.
Every product comes with simple instructions. On our busiest weeks, we can produce and dispatch up to 200 MycoBox and MonoBox grow kits... our guides have to be perfect.
We pioneered the injectable MycoBox design that's been copied across the industry. When you buy from Cylocybe, you're getting the genuine product.

Spawn, substrates & supplies
Mushroom growing supplies.
Looking for Vermiculite, Perlite, Coco Coir, Brown Rice Flour or some other mushroom growing supply? We stock just about everything you can want in this hobby!
Vermiculite (10L)
Expanded mineral flake that soaks up water and lets it go slowly. The standard moisture buffer for PF Tek cakes, bulk coir mixes and casing layers.
Perlite
Expanded volcanic glass. Used wet as a humidity buffer in fruiting chambers, and dry as an airy amendment in substrate and casing mixes.
Coco coir
Coco Coir (650g Brick)
A compressed block of coconut-fibre coir. Add boiling water and it breaks down into a clean, water-holding bulk substrate for fruiting mushrooms.
Brown Rice Flour
Organic wholegrain brown rice flour, the nutrient half of a classic PF Tek substrate. You mix it with vermiculite and water, sterilise it in jars, then grow from it.
Self-Healing Injection Ports (10)
Grey butyl rubber ports that fit a 12mm hole in any jar lid, so you can inoculate through a needle without opening the jar. The rubber reseals as the needle pulls out.
SporeKitβ’ 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 β
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.

What customers say.
Your experience makes a huge impact, personally and professionally. Fewer than 1% of customers leave a review, so your story is a powerful guide for other mycoscopy geeks and growers. That's why we don't ask for feedback straight away. We wait a couple of months to give you a proper chance to test our products. When you see that invitation email, we'd be massively grateful for your honest feedback.
This is my second order and itβs as perfect as my first one. If I had a criticism it would be I preferred the brownie I received with my first order as opposed to the cookies I received with my second, thatβs how pleased I am with the service from you. Ps the cookies were nice though
I was blown away by extra snack bars in the box it hasnβt been 5 seconds and Iβm chewing on it, the rest of the day was legendary due to that occurrence. But donβt expect it, it wonβt be a surprise then. And after all maybe Its for higher value orders or Iβm just special, but overall its a value packed easy peasy to understand package I love these people behind all this. Itβs the easiest thing i could have gotten, life is easy.
I bought, I grew, I harvested, and I consumed. I waited for all four before leaving a review. I am a first time grower, hence I even dehydrated my culinary mushrooms on my radiator. I ended up with about 28 grams of culinary mushrooms after drying, and that was after throwing my brick out after 3 flushes, even though it could have handled at least one more - mainly because the mycelium was looking tired. My fault, I'm only new. Very happy with product. Better than I expected. Start to end-of-third-flush took 2.5 months.
Well packaged, and with absolutely no signs of contamination when viewed under a microscope. I imagine that if a hardened criminal were to cultivate them, by now the spores would be busily colonizing a spawning substrate with pure white mycelium.

Frequently asked questions
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 β₯0.1 Β΅m 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 of dispatch depending on whether you pick Express or Economy, 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.
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. MycMonsterβ’ 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?
Optional cover you add in the basket. If a covered item lets you down, a like-for-like replacement drops into your basket for Β£0, no questions asked. We may still allow some replacements regardless, but this will be judged on a case-by-case.
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).

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...!)
