Golden Teacher Grow Kit XL 2100 ml – GetMagic®

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.

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.

Great XL growkit experience Review by Aqua Indica

Rating

In the past i bought an XL growkit from another site and it was a disaster. I only got 3 medium sized shrooms and after the flush growkit died. So i was sceptical about buying the XL one, but my fear was in vain. The XL growkit from magic mushroom shop is high above my expectations. It was the first time i got big and compact shrooms and not the thin shrooms i was used to. The largest weighs 2.7g (dried), i waited with this review because i wanted to see what will be after the first flush, and i can say that they just keep growing so i can pick one or 2 every day or so. This experience was above all my expectations and im gratefull to magic mushroom shop to provide it. Will order again. (Posted on 11/29/2023)

Wery fast Review by Ugougo

Rating

Everything is fine with this store! The first outbreak is 280, and I think I harvested it very early. Because only one or two hats were open. The second one is still growing, but there are noticeably fewer mushrooms, and mostly where there were none last time. The second time I filled in non-bottled water, perhaps I did not carefully harvest the first crop. In any case, it is very exciting and interesting. Thank yuo! (Posted on 9/4/2023)

Excellent Quality kit Review by Frog

The kit was fully colonised by the time I received it, so I could put it straight to fruiting conditions.
Instructions were clear, easy to use. Following the directions yielded a couple of really massive mushrooms, one was 70g wet! These followed by dozens of pins still growing now, still on my first flush so far, and the results are great! (Posted on 7/5/2023)

Growth Kit Failed, 0.68 grams dried and only 1 flush Review by Tommy

Rating

I followed the instructions clearly to the absolute fullest, the room temperature at all times was 22-23 celcius, everything disenfected, shipping took around 8 days and I proceeded with the kit straight away. First flush produced 0.68 grams dried, I still had my hopes up for the second flush, but nothing, keeping in mind I was very patient with it, gave a third go, it's now been over 5 weeks since 3rd time, but nothing. However, based on the reviews the growkit works just fine, therefore giving this product 4 stars believing that this was a unique black swan event. Most dissapointing part is I waited so long for anything to grow, but nothing. My primary objective would be to find a resolution by receiving a replacement product, as I believe that would be the most fair action, as again based on the reviews the growkit works well and I made sure to follow the instructions diligently, makes me believe this was a unique case.

MMS customer service edit: Thank you for contacting us through email. We are happy we came to a fitting solution. (Posted on 6/8/2023)
