Grow kits
by Azarius
The Golden Teacher grow kit is a fully colonised Psilocybe cubensis cultivation kit that produces 300–600 g of fresh mushrooms across up to 3 flushes. It ships ready to fruit — no inoculation, no mixing, no sterile technique required. Open the box, add water, and your first harvest is 2–3 weeks away. There's a reason this is the world's best-selling mushroom kit: it works, it's forgiving, and the strain itself has a character that keeps people coming back.
Everything you need to start growing is already in the box. The substrate is fully colonised — meaning the mycelium has already done its work through the rye grain, and a perlite/vermiculite casing layer sits on top ready to trigger fruiting. No spore syringes, no agar plates, no laminar flow hood. This is cultivation with the hard part already done for you.
| Contents | Details |
|---|---|
| Colonised substrate | Rye-grain base, fully colonised with Golden Teacher mycelium |
| Casing layer | Perlite/vermiculite mix — retains moisture, triggers pinning |
| Grow bag | Transparent bag with built-in air filter for gas exchange |
| Paperclips | For sealing the grow bag between misting sessions |
The grow bag has a microporous air filter built in. This lets fresh air exchange happen while keeping contaminants out — it's the same principle as a sterile lab filter, just scaled down for home use. The paperclips keep the bag sealed between your daily misting, maintaining the humidity the mushrooms need to fruit properly.
Here are the numbers that matter. The Golden Teacher sits in the moderate range for potency — strong enough to be unmistakable, gentle enough that a slightly imprecise dose won't send you sideways.

A note on that yield range: 300 g is what you'll get if conditions are decent. 600 g is what happens when temperature, humidity, and fresh air exchange are dialled in properly. Most first-time growers land somewhere around 400 g — which is still a very generous amount from a single kit.
Complete your setup: a Thermo/Hygrometer lets you monitor temperature and humidity inside the grow bag — the two variables that matter most. If your room runs cool, a Heat Mat keeps the substrate at the 23–25 °C sweet spot without you having to heat the entire room.
We've been selling mushroom grow kits since 1999. In those 25+ years, we've guided thousands of first-time growers through the process, and the recommendation has never changed: start with Golden Teacher. Not because it's the most potent or the most exotic — but because it's the most reliable.
Golden Teacher mycelium colonises aggressively, which means it outcompetes contaminants that would stall weaker strains. The fruiting bodies are large and easy to identify when they're ready for harvest — you're looking for the veil under the cap to tear, and on Golden Teachers that veil is obvious. Compare that to something like Mazatapec, where the caps stay small and the harvest window is tighter. Or McKennaii, which hits harder but is noticeably fussier about temperature swings. Golden Teacher just gets on with it.
The one honest limitation: Golden Teacher isn't the fastest coloniser in our range. The B+ strain tends to pin a few days earlier, and if speed is your priority, that's worth considering. But for a first grow, we'd pick consistency over speed every time. A kit that reliably produces 3 full flushes beats one that races to a single flush and then stalls.
The single most common mistake we see? People opening the kit, setting it up, and then checking on it every 30 minutes. Mushrooms don't grow faster when you watch them. What they do is dry out faster every time you open that grow bag. Mist once or twice a day, seal the bag, and walk away. The pins will appear when they're ready — usually around day 7–10.
The second most common issue: temperature. Below 20 °C, the mycelium slows down dramatically. Below 18 °C, it can stall entirely. We get emails about "dead kits" every winter, and 9 times out of 10 the answer is the same — the room was too cold. A cheap heat mat solves this instantly. Keep the substrate between 23 and 25 °C and the Golden Teacher does the rest.
One more thing we've noticed over the years: the smell. When the kit is fruiting properly, you'll notice a clean, earthy, slightly sweet mushroom scent — like damp forest floor after rain. If it smells sour or acidic, something has gone wrong with contamination. A healthy Golden Teacher kit smells good. Trust your nose.
The whole process takes about 15 minutes of active work, spread across 2–3 weeks. Here's the step-by-step:
The Golden Teacher earned its name from the reflective, golden-capped fruiting bodies and the introspective character of the experience. According to the NCCIH, when people take psilocybin, their bodies convert it to psilocin, a chemical with psychoactive properties similar to LSD — both are classic serotonin receptor agonists (nccih.nih.gov). Onset is typically 30–45 minutes on an empty stomach, with the full experience lasting 4–5 hours.
Potency sits in the moderate range. A 2024 analytical study published in ACS Chemical Neuroscience identified a putative hydroxypsilocybin derivative in Golden Teacher specimens specifically, demonstrating the varied alkaloid profile this strain can produce (PMC12015540). In practical terms: Golden Teacher is strong enough to be clearly active at modest doses, but it doesn't have the intensity ceiling of strains like Penis Envy or Albino A+.
According to research published in the Journal of Psychopharmacology, high-dose psilocybin experiences are associated with feelings of unity, peace, and joy, along with a sense of transcending time and space (PMC7751062). At the moderate doses Golden Teacher typically delivers, the character leans more toward reflective and warm than overwhelming — which is exactly why it's earned a reputation as a "teaching" strain.
Nausea is the most commonly reported side effect, particularly during the first 30–60 minutes. Eating lightly or fasting for 2–3 hours before can reduce this. Some people brew a tea from the dried mushrooms and strain out the solid material, which is easier on the stomach.
Psilocybin interacts with serotonergic medications. SSRIs (fluoxetine, sertraline, and similar antidepressants) may blunt or unpredictably alter the effects. MAOIs are a more serious concern — they inhibit the enzyme that breaks down psilocin, potentially intensifying and prolonging the experience well beyond normal duration. If you're on any medication that affects serotonin, do your research before combining.
A case report in the Journal of Medical Toxicology documented acute renal injury following confirmed Psilocybe cubensis consumption (PMC6322052). While this is rare and the clinical context involved unusually large quantities, it's a reminder that hydration matters and that pre-existing kidney conditions warrant caution.
Set and setting remain the most reliable predictors of a positive experience. A comfortable space, a trusted companion, no obligations for the next 6–8 hours, and a dose you're confident about. Start lower than you think you need to — you can always take more next time, but you can't take less once it's in.
First pins typically appear 7–10 days after setup. Harvest-ready mushrooms follow 3–5 days after that, putting your first flush at roughly 2–3 weeks total. Subsequent flushes take 1–2 weeks each after rehydration.
Between 300 and 600 g of fresh mushrooms across up to 3 flushes. The first flush is usually the largest. Dried weight is roughly 10% of fresh weight, so expect 30–60 g dried total.
Keep the kit between 23 and 25 °C for optimal results. Below 20 °C, growth slows significantly. Below 18 °C, colonisation can stall entirely. A heat mat underneath the kit is the easiest fix if your room runs cool.
No sterilisation equipment is needed. The substrate arrives fully colonised, so the main contamination risk is your hands. Wash them thoroughly with soap before handling the kit. Work in a clean room with minimal airflow — don't set up the kit next to an open window or a running fan.
Harvest when the veil beneath the cap starts to tear. This is the thin membrane connecting the cap edge to the stem. Once it tears, the cap opens and begins dropping dark spores. Harvesting just before or as the veil tears gives you the best potency-to-weight ratio and keeps the substrate clean for the next flush.
Occasionally, yes — some growers squeeze out a 4th flush. But yields drop sharply after the 3rd, and contamination risk increases with each cycle. We'd say 3 solid flushes is the realistic target. After that, the substrate is spent.
Keep it in the fridge at 2–8 °C, unopened. The colonised mycelium stays viable for a few weeks in cold storage. Don't freeze it — ice crystals damage the mycelium. For best results, set it up within a week of delivery.
Golden Teacher is more forgiving to grow and moderate in potency — the reliable all-rounder. McKennaii is noticeably more potent and tends to be more sensitive to temperature fluctuations during fruiting. If it's your first kit, Golden Teacher. If you've already grown a few kits and want something stronger, McKennaii is the natural next step.
