Grow kits

The Golden Teacher grow kit in Ready-2-Grow Bag format is a sealed, fully inoculated 2 kg grow bag that produces up to 500 g of fresh Psilocybe cubensis mushrooms with absolutely no setup. Golden Teacher is the most widely cultivated cubensis strain on earth — and the single best-selling strain at Azarius for over a decade running. This bag arrives colonised and ready to fruit. Open it, give it light and air, and harvest your first flush in 2–3 weeks.
Golden Teacher outsells every other strain at Azarius by a comfortable margin — and has done so consistently since we started tracking. The reason is straightforward: moderate potency, forgiving growing conditions, and a warm, introspective character that works whether it's your first grow or your fiftieth.
Potency sits at 0.4–0.6% psilocybin by dry weight according to Gotvaldová et al. (2021, Journal of Chromatography A). A separate analysis published in 2024 found Golden Teacher total tryptamine content at approximately 0.30% of dry biomass (PMC12658598), placing it in the intermediate range. That's roughly half of what Albino Penis Envy delivers and about 30% less than McKennaii — which is precisely why it works as a starting point. You get a full, clear experience without the intensity that catches people off guard.
The strain first appeared in cultivation circles in the 1980s and earned its name from users who consistently described the experience as instructive rather than overwhelming. According to a 2023 study exploring Psilocybe cubensis strains, strain-level descriptions are "predominantly sourced from non-academic, community" knowledge bases (PMC11856550) — which is a polite way of saying growers have been sharing notes on Golden Teacher for four decades, and the consensus hasn't shifted. It teaches. That's what it does.
The Ready-2-Grow Bag is a sealed all-in-one cultivation system. No casing layers to apply, no misting schedule to memorise, no separate substrate to sterilise. The bag contains 2 kg of growing medium already inoculated with live Golden Teacher spores, fully colonised and ready to fruit.

The bag itself acts as the growing chamber. The filtered patch allows gas exchange while keeping contaminants out. You don't need a separate fruiting chamber, a humidity tent, or a spray bottle on a timer. That said — and this is the honest limitation — the sealed format means you have less control over fruiting conditions than you would with a traditional grow kit and a propagator. If you're the type who wants to dial in surface conditions precisely, a standard kit with a separate casing layer gives you more to work with. But if you want mushrooms with the least possible effort, this is the format.
We carry several cubensis strains as Ready-2-Grow Bags. Here's how Golden Teacher stacks up against the two most common alternatives people ask about.
| Feature | Golden Teacher | McKennaii | B+ |
|---|---|---|---|
| Potency | Moderate (0.4–0.6%) | Above average (~0.7–0.8%) | Moderate (0.4–0.6%) |
| Growing difficulty | Very forgiving | Slightly more sensitive | Forgiving |
| Character | Warm, introspective, instructive | Visual, intense, philosophical | Gentle, physical, social |
| Yield potential | Up to 500 g fresh | Up to 500 g fresh | Up to 500 g fresh |
| Best for | First-time growers and first-time users | Experienced users wanting more intensity | Social settings, relaxed sessions |
| Our take | The default. Start here. | Step up once you know your tolerance | Good alternative if Golden Teacher is out of stock |
If you're genuinely unsure, pick Golden Teacher. We've been saying that since 1999 and we haven't been wrong yet.
The whole point of this format is simplicity. Follow these steps and your first pins should appear within 7–14 days.
We've sold thousands of these Golden Teacher grow kits. The pattern is remarkably consistent: first-time growers get results. The colonised substrate in the Ready-2-Grow Bag is dense and white — you can feel the weight of it through the packaging, and when you open the bag there's that distinctive earthy, mycelial smell that tells you the culture is alive and healthy. Pins show up fast, usually within the first 10 days. The mushrooms themselves grow with thick, sturdy stems and those characteristic golden-brown caps that flatten out as they mature.
The most common mistake we see? Impatience. People open the bag, see nothing for five days, and start fiddling — overwatering, moving the bag, poking the substrate. Leave it alone. Golden Teacher is forgiving, but it still needs stable conditions. Set it somewhere warm with indirect light and resist the urge to check it every two hours.
The second most common mistake is harvesting too late. Once the veil tears, spore drop begins — you'll see a dark purple-black dusting on the caps below. It doesn't ruin anything, but it looks messy and can suppress the next flush slightly. Harvest when the veil is just starting to separate. Better a few hours early than a day late.
Golden Teacher contains psilocybin and psilocin as its primary active compounds. Psilocybin converts to psilocin in your liver through dephosphorylation — psilocin is the molecule that binds to serotonin 5-HT2A receptors and produces the psychoactive effects.
According to Gotvaldová et al. (2021), Golden Teacher falls in the 0.4–0.6% psilocybin range by dry weight. A 2024 quantitative NMR analysis (PMC12658598) measured total tryptamine content at approximately 0.30% of dry biomass, and also identified a putative hydroxypsilocybin derivative in Golden Teacher specimens (PMC12015540) — a finding that hints at the chemical complexity still being mapped in cubensis strains.
Onset on an empty stomach runs 45–60 minutes, which is slower than high-potency strains. This is actually an advantage for less experienced users — it gives you time to settle in before effects build. Duration runs 4–5 hours from onset to baseline. We get asked "why isn't it working yet?" at least twice a week in the shop. The answer is almost always: wait. Redosing before the 90-minute mark is how people end up with more than they bargained for.
Golden Teacher's moderate potency makes it more manageable than strains like McKennaii or APE, but it still deserves respect. Set and setting matter more than strain choice. A comfortable, familiar environment with someone you trust nearby makes a bigger difference than any dosing calculator.
If you take SSRIs (fluoxetine, sertraline, and similar), be aware that these medications may blunt the effects of psilocybin or cause mood instability. MAO inhibitors are a more serious concern — the combination can intensify effects unpredictably. If you're on any medication that affects serotonin, do your homework before proceeding.
According to a case study published in 2024 (PMC11133386), a patient consumed 1 g of dried Golden Teacher mushrooms in a clinical context, demonstrating the strain's use in emerging research settings. This is not medical advice — it's context showing that Golden Teacher is the strain researchers reach for when they need a predictable, well-characterised cubensis variety.
Complete your setup: a digital scale accurate to 0.01 g makes dosing dried mushrooms precise instead of guesswork — check out our Scales collection. If you want to preserve your harvest long-term, a food dehydrator and airtight storage jars keep potency stable for months. And if Golden Teacher leaves you wanting more intensity next time, the McKennaii Ready-2-Grow Bag is the natural step up.
Up to 500 g of fresh mushrooms across multiple flushes, with the first flush being the largest. Most growers report 200–300 g on the first flush and smaller amounts on the second and third. Dried weight is roughly 10% of fresh weight.
No. The bag is the growing chamber. A spray bottle for misting is helpful but not strictly required — some growers get through the entire cycle without one. A digital scale is worth having for weighing your dried harvest accurately.
Typically 2–3 weeks. Pins usually appear within 7–14 days of opening the bag, and mushrooms reach harvest size 5–7 days after pinning. Room temperature between 21–25°C speeds things up; cooler conditions slow it down.
Yes — most bags produce 2–3 flushes. After each harvest, soak the substrate in clean water for 12 hours, drain, and resume fruiting conditions. Each successive flush yields less than the previous one.
A standard grow kit typically comes as a colonised substrate box that you place inside a separate fruiting bag or propagator. The Ready-2-Grow Bag combines both into one sealed unit — less control over conditions, but genuinely zero setup. If you want the simplest possible route, pick the bag.
Keep the sealed bag in the fridge at 2–8°C. The colonised substrate stays viable for several weeks when refrigerated. Do not freeze it — ice crystals damage the mycelium. Once you open the bag, you're committed to the grow cycle.
Three reasons: it colonises reliably, it tolerates imperfect conditions better than most strains, and its moderate potency (0.4–0.6% psilocybin dry weight) gives a full experience without the intensity of strains like APE or McKennaii. It's the strain we've recommended to beginners since 1999.
Harvest when the veil — the thin membrane connecting the cap edge to the stem — begins to tear. The caps will be flattening out but not yet fully open. If you see dark spore dust on lower caps, you've waited a touch too long. Not a disaster, but aim earlier next time.
