The Cambodia grow kit is a fully colonised Psilocybe cubensis cultivation kit that produces visible pins faster than any other strain we carry. Discovered near the Angkor Wat temple complex in Southeast Asia, this strain colonises rye-grain substrate noticeably quicker than Golden Teacher or B+ — expect your first pins in under 10 days and a harvestable flush within 2–3 weeks. The 1200 ml box ships ready to fruit: colonised rye cake, perlite and vermiculite casing layer, humidity grow bag, and polyfill-filtered air strips. Up to 3 flushes yield 300–600 g fresh (30–60 g dried) from a single kit.
Speed is the single biggest reason people pick Cambodia over other Psilocybe cubensis strains. Where a Golden Teacher kit typically shows its first pins around day 12–14, Cambodia regularly pins before day 10. That difference compounds across multiple flushes — you can realistically complete 3 full harvest cycles in the time it takes some strains to finish 2.
We've sold thousands of grow kits since 1999, and Cambodia is consistently the one we hand to customers who've just had a contamination scare or a slow first attempt. It's not that other strains are unreliable — B+ and Golden Teacher are workhorses — but Cambodia's aggressive colonisation speed leaves a smaller window for contaminants to take hold. The mycelium simply outpaces the competition, both the fungal kind and the unwanted kind.
The one honest limitation: Cambodia fruits tend to be smaller and thinner-stemmed than something like B+ or McKennaii. You'll get plenty of them — the canopy can be dense — but don't expect the chunky, photogenic clusters you see on Golden Teacher grows. What you trade in individual fruit size, you gain in speed and flush consistency.

Cambodia, Golden Teacher, and B+ are the three most popular cubensis grow kits we carry, and each has a distinct personality. Here's how they compare on the metrics that actually matter when you're choosing your next grow.
| Feature | Cambodia | Golden Teacher | B+ |
|---|---|---|---|
| Colonisation speed | Fastest — pins in under 10 days | Medium — pins around 12–14 days | Medium — pins around 12–14 days |
| Fruit size | Small to medium, thin stems | Medium to large, classic shape | Large, thick stems |
| Total yield (fresh) | 300–600 g | 300–600 g | 300–600 g |
| Potency | Moderate | Moderate | Moderate |
| Character | Energetic, uplifting, sociable | Introspective, "teaching" | Warm, visual, forgiving |
| Contamination resistance | High (fast coloniser) | Good | Very good |
| Best for | Speed, social settings, repeat growers | First-timers wanting a classic experience | First-timers wanting large fruits |
Our take: if you want results fast and you're growing in a warm room (23–25 °C), Cambodia is hard to beat. If you'd rather have fewer, larger fruits and a more introspective character, Golden Teacher is the classic for a reason.
The Cambodia grow kit arrives fully colonised, so there's no inoculation, no waiting for jars to colonise, no grain-to-grain transfers. You open the box and start fruiting. Here's the process from unboxing to harvest.
Cambodia is a moderate-potency Psilocybe cubensis strain with a character that leans energetic and sociable rather than heavy and introspective. Effects onset at roughly 30–45 minutes on an empty stomach — slightly faster than Golden Teacher's typical 45–60 minute window — and last 4–5 hours.
The headspace is lucid and clear. Users consistently report enhanced colour perception, gentle geometric patterning on textured surfaces, and a persistent sense of lightness that makes Cambodia one of the better strains for daytime or social settings. Where Golden Teacher "teaches" and McKennaii confronts, Cambodia lifts. Music sounds richer, textures feel more defined, and laughter comes easily. The spiritual dimension is surprisingly present for a moderate-potency strain: the combination of mental clarity and sensory enhancement creates space for reflection without the heavy body load some stronger strains produce.
A practical note from behind our counter: Cambodia's faster onset catches some people off guard. If you're used to Golden Teacher's slower ramp-up, don't redose at the 30-minute mark just because you think nothing's happening. Give it a full 60–90 minutes before making any decisions about dose.
As a general rule, 1 g of dried Psilocybe cubensis is roughly equivalent to 10 g fresh. Cambodia falls within the moderate potency range for cubensis, so standard cubensis dosing guidelines apply. Clinical research into psilocybin has typically used standardised extracts rather than whole mushrooms, but observed dose ranges in community practice and research contexts generally fall into these brackets for dried material: a threshold dose around 0.5–1 g dried, a moderate dose around 1.5–2.5 g dried, and a strong dose above 3 g dried. Fresh weight is approximately 10 times those figures due to water content.
If this is your first grow and your first time, start at the lower end. You can always grow more — that's the whole point of having the kit.
The Cambodia grow kit ships as a living organism — the mycelium is active and colonising. For best results, start your grow within a few days of delivery. If you need to delay, store the unopened kit in the fridge at 2–8 °C for up to 2 weeks. Don't freeze it — ice crystals rupture cell walls and kill the mycelium.
Once harvested, fresh mushrooms keep for about 5–7 days in the fridge in a paper bag (not plastic — they'll go slimy). For long-term storage, dry them thoroughly with a food dehydrator or desiccant until they snap cleanly when bent. Properly dried and stored in an airtight container with a silica gel packet, they'll keep their potency for 6–12 months.
Complete your setup: A Heating Mat keeps substrate temperature stable at 23–25 °C if your room runs cool — Cambodia's speed advantage disappears below 21 °C. Pair with a Digital Thermometer/Hygrometer to monitor conditions inside the grow bag without opening it constantly.
First pins typically appear in under 10 days from the start of fruiting. Your first harvestable flush follows within 2–3 weeks total. Cambodia is the fastest-colonising cubensis strain we carry — noticeably quicker than Golden Teacher or B+.
Most kits produce 2–3 flushes, with a combined yield of 300–600 g fresh (30–60 g dried). The first flush is usually the largest. Proper rehydration between flushes — a full 12-hour soak — is what determines whether you get a strong second and third round.
No grow lights needed. Indirect daylight or a standard room light for roughly 12 hours a day is enough to trigger even pinning. Direct sunlight will overheat the kit and dry out the substrate — keep it off the windowsill.
Aim for 23–25 °C consistently. Cambodia's speed advantage drops off sharply below 21 °C, and above 28 °C you risk bacterial contamination. A heating mat underneath the kit is the simplest fix if your room runs cool.
Harvest just as the veil — the thin membrane connecting the cap to the stem — begins to tear. This is peak potency. Don't wait for the caps to flatten fully; once spores drop onto the cake surface, rehydration for the next flush becomes less effective.
Yes, but not for long. Keep the unopened kit refrigerated at 2–8 °C and start within 2 weeks of delivery. Never freeze it — ice crystals destroy the living mycelium.
That's normal. Cambodia naturally produces smaller, thinner-stemmed fruits in denser clusters. The total yield is comparable to Golden Teacher — you just get more individual mushrooms rather than fewer large ones.
Side pins happen when light or humidity conditions are more favourable at the edges than the top surface. Wrapping the sides and bottom of the grow box in aluminium foil before placing it in the bag redirects pinning to the top where you want it.
