Product Description
Details
Why choose the Golden Teacher XL?
Golden Teacher is the world's most popular magic mushroom strain for good reason — and in the 2100 ml XL format, you get significantly more of what makes it great. Nearly double the colonised substrate means bigger flushes, larger individual mushrooms, and enough yield for multiple sessions from a single kit. If Golden Teacher is your go-to strain, the XL is the obvious upgrade.
Golden Teacher psilocybe cubensis was reportedly discovered growing wild in Florida during the 1980s and has since become the benchmark for home cultivation. The mushrooms are recognised by their broad, elegant caps (20–60 mm) that transition from rich brown to a distinctive golden hue as they mature, set on sturdy stems (40–140 mm) that bruise blue-green. In the XL kit, the greater nutrient reserve produces noticeably larger caps and thicker stems than the standard 1200 ml size.
The experience is insightful and introspective: clear-headed, gently visual, and with a profound, reflective depth. Golden Teacher is the strain most recommended for first-time users because of its balanced, forgiving nature — potent enough to be meaningful yet manageable at standard doses.
Growing the Golden Teacher XL
The method is identical to the 1200 ml kit — same grow bag, same steps, same temperature. Golden Teacher colonises at a moderate pace, so the XL kit may take a few extra days before you see the first pins compared to faster strains like Cambodian or Thai. This is normal — patience pays off. Keep the temperature steady at 23 °C and expect pinning within 12–18 days. The XL typically delivers an extra flush or two, so keep soaking and restarting until the kit stops producing.
Golden Teacher — strain specifications
Frequently asked questions
What's the difference between the 1200 ml and 2100 ml XL kit?
Same strain, same method, bigger box. The XL contains nearly double the colonised substrate, which translates to higher yields (400–800 g vs. 200–400 g), larger individual mushrooms, and typically an extra flush or two. For Golden Teacher — the strain most people come back to — the XL means more sessions from a single kit.
What yield can I expect from this 2100 ml XL kit?
The Golden Teacher XL typically produces 400–800 g of fresh mushrooms across multiple flushes. Golden Teacher is a consistent, reliable producer — not the absolute highest yielder in the range, but dependable flush after flush. Actual yield depends on temperature, humidity, and hygiene during the grow.
I'm a first-time grower — should I start with the standard or XL?
If you've never grown before, the 1200 ml standard kit is the safer starting point — it's more forgiving if you make small mistakes and you'll learn the process with less at stake. Once you've completed a successful grow and know the routine, the XL is the natural next step. That said, the method is identical — confident beginners can absolutely start with the XL.

- Another great product from the guys Review by Justin

I guess the best review I can give is the fact that I am now a regular customer and I have never been anything but impressed with not only the products that I have purchased, but also the chill, laid back, eager to help and knowledgeable service provided every time.Rating
I stumbled across The Magic Mushroom Shop, having had a nightmare with other vendors, so I can tell everyone, not all magic mushroom shops are the same.

Very fast shipping! Only 3 business days to Eastern Europe!Rating
This is my first growing kit. At the beginning I made a small mistake with hydration, but despite that I still got 156 grams of fresh yield on the first flush! Incredible, but after the soak it took less than three days and new pins were already popping up! At first glance this second flush looks like it’s going to be even bigger than the first.
I’m very satisfied – an excellent kit! Just follow the instructions and everything will be fine. But as my case shows, it even forgives beginner mistakes.
Highly recommended, and thank you for the super fast and discreet delivery! (Posted on 8/18/2025) - Product is good, but.... Review by Sherban

I made a mistake.Rating
Instead of instantly fruiting once i got it, i stored it for 2 weeks and mycelium got granular and dry. So dry i had to poke knife cuts and felt like sand inside.
I put them in water and stored in fridge 24h, then it popped about 50 pins, however it didn't went optimal. It could have been super generous, but my mistake took a toll on it :( (Posted on 8/5/2025) - Thanks to customer service. Review by Aqua Indica

This is not a review for the grow kit, like usually but a thanks to the crew at magic mushroom shop. I had quite a few problems with my last grow kit I ordered, and was about to throw it all away, but before that I wrote to the customer service. I would love to thank them, especially to a miss that got my ticket. They gave me a lot of suggestions how to tackle my problem and were quick to fully answer my question. All that time they remained professional and at the end we have found the solution to my problem. Its really reassuring to know, that people here genuinely care about their customers and will do all they can to help solve a problem. This situation solidified my trust in them and would recommend magic mushroom shop to everyone. (Posted on 7/22/2025)Rating - Wunderwelt der Pilze Review by Marco

Moin. Unser erstes Growkit. Lieferung kam in einem angemessenen Zeitraum. Meine nicht beabsichtigte Doppeltzahlung wurde ohne wenn&aber zurück erstattet. Beim Aufstellen wurde soweit auf alles beachtet was empfohlen wurde. Nach 3 Wochen war noch nicht zu sehen. Dann den abgedunkelten Fensterplatz Standort gewechselt. In den dunklen Wäsche/Trockner Raum. Seitdem fahren alle zwei Tage eine kleine Ernte ein. Unglaublich! Hatte schon ein Microdosing Trip. Sehr geil.

This is my third time buying in this website and the second time buying this grow kit. Until now I had only good experiences with this guys, they delivery is incredible fast, the customer service is very helpful and the grow kits did always good. I've got 4 flushes out of this one last time, now waiting for my last ordered grow kit to start fruiting.Rating
Thank you guys, you're doing a great job! (Posted on 4/4/2025) - Addition to "Hoping for the best" review. Review by AquaIndica

I would like to change my review from 4 to 5 stars. When i wrote the first review i want sure what will happen with my grow kit, but now i have great news. As i said before there were just a few shrooms at the start, but new ones just kept coming and coming and i got a massive yield from the first round. Then i did the first flush and the same story repeated itself (few pins at the start, but new ones just kept growing, for another big yield). Now i am on the second flush, waiting for more pins.Rating
Many thanks to the team for MMS edit, it shows that they really care. I would rate this 11/10 if i could. Every growkit i bought from here was a success. Would highly reccomend. Thank you and much love to ya'all. :) (Posted on 3/10/2025) - the micelle was not in terminal phase Review by Kostadin

this time i am very displeased. the mycelium had not covered all the medium in the middle, I had to cut and clean it and cut it into pieces so that it would not infect the part that was in the middle of the medium. If you don't believe me, I have photo material. please, next time when I order an infected culture medium I will get it, not half infected and wait for it for 20 days. if not, next time I will order spores.

Previous growkit i bought here was epic. The yields were massive and would recomend it to everyone. 10/10Rating
But this last growkit i bought seems a bit off, thats why i will give 4 stars and not 5 (for now). I just started to see some pins few days ago and proceeded to fan it once a day and misting it. There are 4 mushrooms growing now and 2 or 3 miniature pins. (When pins on previous growkit started to appear the cake was full of them, the one i have now seems kind of empty for now). This might change in a few days i hope at least.
I will write a new review after few flushes as i see what will become of this cake.
[MMS edit: Alright! Since it is winter time at the time of writing, try to keep the temperature up around 23ºC. If you already doing this, keep us updated on the progress!] (Posted on 2/8/2025) - Highly recommended Review by Maksim

The Golden Teacher is fantastic! It arrived quickly, was well-packaged, and was easy to use with clear instructions. The mushrooms grew abundantly and were of great quality. Highly recommended!Rating
Be careful with the environmental temperature, for me it turned out to be too hot with the heating mat used, so the substrate started to dry and shrink in the plastic box. Finally, I use a thermometer and no heating mat. (Posted on 1/22/2025) - Brilliant Review by Mark

Got an amazing 320g(wet) from the first yield. Took about 30 days to get there but worth it. Brilliant service and communication as always. Had a couple of issues before but the customer service is just 100%. Will be buying again very soon (Posted on 1/4/2025)Rating - The Teachers XL in Every sense of the word Review by Alberto
