Spore Syringes
by Mondo
The Mondo Spore Syringe Psilocybe Cubensis Cambodia is a 20ml syringe loaded with Psilocybe cubensis Cambodia spores suspended in sterile solution, ready to inoculate your substrate of choice. This strain was originally collected near the Angkor Wat temple complex in Cambodia — discovered by a mycologist who was actually in the country filming other species entirely. Happy accident. It's become one of the most popular beginner strains for a reason: fast colonisation, forgiving growing conditions, and relatively predictable flushes that don't punish small mistakes the way fussier varieties do.
The Cambodia spore syringe is the one we hand to first-time cultivators without hesitation. We've been selling Mondo syringes since they launched, and the Cambodia consistently produces the fewest "help, something went wrong" messages of any strain in the range. That's not marketing — it's 25 years of watching what actually happens when people take these home.
What makes Cambodia so forgiving? It colonises substrate fast — noticeably faster than something like the McKennaii or Moby Dick. Speed matters because every extra day your grain sits partially colonised is another day contaminants have a window to move in. Cambodia closes that window quickly. The mycelium is aggressive, rhizomorphic, and visibly healthy even when conditions aren't textbook. We've seen Cambodia batches fruit successfully in rooms that were a few degrees too warm, in tubs with imperfect humidity, in setups that would have stalled a more sensitive strain entirely.
The one honest limitation: Cambodia isn't known for producing the largest individual fruits. You'll get solid, medium-sized mushrooms rather than the chunky specimens you might see from a B+ or Golden Teacher. The yields are reliable and consistent across flushes, but if you're after photo-worthy giants, the Ecuador or Treasure Coast might scratch that itch better. For a first grow where you want to actually see results and learn the process? Cambodia, every time.
Each Mondo spore syringe contains 20ml of sterile water with Psilocybe cubensis Cambodia spores evenly distributed throughout. The syringe comes sealed with a cap, and a sterile 18-gauge needle is included in the packaging. Mondo also provides an alcohol swab for sterilising injection ports or surfaces before inoculation.

Complete your cultivation setup with a Mondo Liquid Culture Vial if you want to work with live mycelium instead of spores — liquid culture colonises even faster than spore solution. Already growing a different strain? The Mondo Spore Syringe Psilocybe Cubensis Golden Teacher is the other top pick for beginners, with slightly larger fruits and a reputation for being equally forgiving.
A spore syringe inoculates sterilised grain substrate with Psilocybe cubensis spores. The process is straightforward, but sterile technique is everything — one ungloved hand or one skipped flame-sterilisation step can cost you the entire batch. We've seen it happen hundreds of times. Here's the process done right:
Cambodia has been in the Mondo range for years, and it's the strain we've moved the most syringes of — not because we push it, but because growers come back for it. The colonisation speed is genuinely noticeable. Side by side with a McKennaii syringe inoculated on the same day, the Cambodia jar will typically show visible white mycelium 2–3 days sooner. For a new grower checking their jars every morning wondering if anything is happening, that speed is reassuring.
The other thing we appreciate about this strain: it doesn't stall easily. Some varieties — Moby Dick comes to mind — can slow down or stop colonising if temperatures fluctuate or humidity drops. Cambodia just keeps pushing through. We've had customers tell us their Cambodia tubs fruited successfully in unheated sheds in November. We wouldn't recommend that approach, but the fact that it worked says something about the strain's resilience.
One thing to watch: shake that syringe properly before you inject. The spores settle to the bottom during storage, and if you skip the shake, your first jar gets a concentrated blast while the last jar gets mostly water. Twenty seconds of gentle shaking sorts it out. You'll see the clumps break apart — that's what you're looking for.
If you're choosing between Cambodia and another entry-level Psilocybe cubensis strain, here's how they compare based on what we've seen over the years:
| Characteristic | Cambodia | Golden Teacher | B+ |
|---|---|---|---|
| Colonisation speed | Fast (5–10 days visible) | Moderate (7–14 days visible) | Moderate (7–14 days visible) |
| Contamination resistance | High | High | High |
| Fruit size | Small to medium | Medium to large | Medium to large |
| Yield consistency | Very consistent | Consistent | Consistent |
| Temperature tolerance | Wide range (22–30°C) | Moderate (24–28°C optimal) | Wide range (22–28°C) |
| Best for | First-time growers wanting fast results | First-time growers wanting larger fruits | Growers wanting a balance of both |
We'd pick Cambodia for a first grow and Golden Teacher for a second. Cambodia teaches you the process with minimal drama; Golden Teacher rewards you with more impressive-looking flushes once you've got the basics down.
Store the Mondo Cambodia spore syringe in the refrigerator at 2–8°C. At this temperature, the spores remain viable for up to 12 months. Don't freeze the syringe — ice crystals can damage the spores. Keep it in its original sealed packaging until you're ready to use it, and avoid exposing it to direct sunlight or temperatures above 25°C during storage. If you've used part of the syringe, recap it with the original cap and return it to the fridge. The remaining solution stays good for several months as long as sterile technique was maintained during use.
It's a 20ml syringe filled with sterile water containing suspended Psilocybe cubensis Cambodia spores. You use it to inoculate sterilised grain substrate. The Cambodia strain originates from near Angkor Wat in Cambodia and is known for fast colonisation and forgiving growing characteristics.
At 2–3ml per injection point, a single 20ml syringe inoculates roughly 6–10 jars or grain bags. If you're using multiple injection points per container (common with larger bags), you'll get fewer containers per syringe but more even colonisation.
Spores settle to the bottom during storage. Give the syringe a good 15–20 second shake before inspecting or using it. You'll see tiny dark clumps break apart and cloud the solution — that's normal and means the spores are present and dispersing properly.
Strongly recommended but not strictly required. A still air box (a clear plastic tub with arm holes) dramatically reduces airborne contamination during inoculation. Without one, work in the cleanest, stillest room you have — bathroom after a hot shower works in a pinch, since steam pulls particles from the air.
Visible mycelium typically appears within 5–10 days at 24–28°C. Full colonisation of a standard grain jar takes 2–3 weeks. Cambodia is noticeably faster than most other cubensis strains, which is one reason we recommend it for beginners.
Grow kits from Mondo come pre-inoculated and fully colonised — they don't need a spore syringe. Spore syringes are for growers working from scratch with their own sterilised grain substrate. If you want the simplest route, grab a ready-made grow kit. If you want to learn the full cultivation process, the spore syringe is where you start.
A spore syringe contains dormant spores in sterile water. A liquid culture vial contains living mycelium already growing in a nutrient solution. Liquid culture colonises faster because the mycelium has a head start, but spore syringes are more widely available and store longer. Cambodia's natural speed makes the difference less dramatic than with slower strains.
