The Golden Teacher growkit ships with a fully colonised Psilocybe cubensis substrate — ready for observation straight out of the box. You don’t need extra equipment, substrate or prior experience: a stable 23–25 °C room and a little patience cover the entire cycle.
What’s inside the Golden Teacher growkit
Each kit contains a 1800 ml container with a fully colonised substrate — Golden Teacher mycelium on an organic base. Gross weight is approximately 1.1 kg, with a micro-filter bag that keeps the internal microclimate stable without manual intervention.
The kit works as a closed system: the substrate supplies all nutrients, the filter patch regulates gas exchange, and built-up humidity sustains pinning without misting. You leave it at room temperature, keep it out of direct sunlight, and observe.
Who Golden Teacher is for
Golden Teacher is one of the oldest and most widely documented Psilocybe cubensis isolates. If you’re starting your mycology hobby, this is the strain most community guides recommend first — colonisation is vigorous, the isolate is forgiving, and the community literature is exhaustive.
The “Teacher” label isn’t marketing: in user reports across Shroomery and r/shrooms Golden Teacher is consistently described as introspective rather than overwhelming. That reputation is one reason it remains the most picked cubensis strain worldwide, alongside our other staples like McKennaii, Jack Frost and Hillbilly Pumpkin.
Golden Teacher vs other strains
All our kits share the same 1.1 kg / 1800 ml physical format — differences live in pinning character, appearance, genetic lineage and community descriptions.
| Trait | Golden Teacher | McKennaii | Jack Frost | Hillbilly Pumpkin |
|---|---|---|---|---|
| Cap appearance | Golden caps with white speckling, slender stems | Darker brown caps, compact build | Leucistic/albino-like, frosted look, bluish gills | Pumpkin-orange caps, thick marshmallow stems |
| Tryptamine indication | ~0.63–0.90% | ~0.80–1.00% | ~0.83% (up to 1.00%) | ~0.40–0.60% |
| Experience descriptors | Introspective, “lesson-like” | Intensely visual, longer onset | Strong visuals, euphoria, time distortion | Gentle, relaxing — “microdose favourite” |
| Genetics | Florida natural isolate (~1970s) | Unknown cultural history, named after Terence McKenna | Hybrid of True Albino Teacher × Albino Penis Envy | Wild Arkansas isolate — “pumpkin” phenotype |
Golden Teacher stands out for stability and an introspective narrative — hobbyist forums have been calling it a “teaching” strain for decades. McKennaii suits those looking for a more visually intense profile. Jack Frost pairs leucistic genetics with a clearly euphoric character. Hillbilly Pumpkin, with its lower tryptamine range and striking appearance, sits closer to a mycology curiosity prized by collectors.
How to start
The process reduces to three steps:
- Order the kit — EU shipping from Poland, typically 3–5 business days.
- Open and place — remove the kit, straighten the bag and stand it upright in a bright spot away from direct sunlight.
- Hold 23–25 °C — that’s the only real variable. No misting, no venting, no daily intervention.
A full step-by-step walkthrough lives in our growkit instructions.

Frequently asked questions
What does the Golden Teacher growkit cost?
The current price is shown at the top of this page. It covers the complete kit with mature mycelium ready for observation.
Is the Golden Teacher growkit legal in the EU?
The kit contains Psilocybe cubensis mycelium, which is not treated as a controlled substance in most EU jurisdictions. Fruiting bodies containing psilocybin are regulated almost everywhere in the EU — verify local rules in your country before any handling beyond observation of mycelium.
What yield can I expect from one kit?
A 1800 ml Golden Teacher kit typically yields 250 g+ of total biomass across multiple flushes. Exact figures depend on temperature stability, humidity and handling discipline.
How fast does the mycelium colonise?
Golden Teacher mycelium usually colonises the substrate within 2–3 weeks. The full observation cycle takes 6–8 weeks. Cultivation of fruiting bodies containing psilocybin is restricted in most EU countries — check your jurisdiction.
How is Golden Teacher different from McKennaii?
Both are Psilocybe cubensis cultivars. Golden Teacher is the reference isolate — stable and well-documented. McKennaii is known for different fruit-body morphology and typically a more visually intense profile. Difficulty of cultivation is comparable.
Does the kit need any extra equipment?
No — the kit is fully automated and does not require misting or venting. The only condition is a stable 23–25 °C. Before starting observation, check the rules in your jurisdiction.
The growkit contains mycelium, which is not treated as a controlled substance in most EU jurisdictions. Cultivation of fruiting bodies containing psilocybin is regulated in most countries — legal status varies by jurisdiction, so verify local laws before handling.
