Magic Mushroom Grow Kit Golden Teacher by Mondo®

The Golden Teacher psilocybe cubensis is a great mushroom for starters. The G.T. magic mushroom spore is a slow colonizer with rizomorphic mycelium. But the colonizing already happened! The Golden Teacher will fruit flush after flush on a Brown rice flower (BRF) substrate. The beautiful golden colored mushroom caps and its wise teachings has given the Golden Teacher its name. The Golden teachers mushrooms grow medium sized to huge when in the right conditions.

Product Description

Years of planning and testing has resulted in the next generation of Mondo® Golden Teacher Magic Mushroom grow kits. The Mondo® Grow Kit Golden Teacher has become better than it ever was. Compared to the first generation of Psilocybe cubensis Mondo® Golden Teacher Grow Kit, the next generation is improved with:

  • Larger yields, more mushrooms
  • More flushes*
  • Better resistance against contaminations
  • Different, but easier instructions

*some strains produce more flushes than others. The first three flushes are the largest.

Meet the new standard of easy grow kits

The Psilocybe cubensis Mondo® Golden Teacher Magic Mushroom grow kit is slightly different than the grow kits you might have used before. This is seen only in the substrate recipe and is a secret not just shared with everyone. Not even with us!

Just like the previous and other easy grow kits, you do not need to use additional spores. During the laboratory process, the spores have developed into mycelium inside the substrate (the cake) in the grow box. The mycelium has fully colonized the substrate and is ready to grow mushrooms.

How to store the grow kit correctly

It is recommended to start the cultivation process right away. If you decide to start growing later, you may store the grow kit in the refrigerator (2°C to 8°C) for 2 weeks. First, wrap the grow kit in a plastic shopping bag and close it well.


  • 1x grow box – This contains substrate with active mycelium (the cake)
  • 1x grow bag – The bag has a micron filter to keep contaminants out
  • 1x paperclip – For closing the grow bag.

You need

  • Misting Bottle – Misting is needed for the humidity level
  • Potable water – For misting and soaking
  • Clean environment – Work clean to give other fungi and bacteria (micro organisms) no chance to contaminate.

We recommend using

How to prepare the room and yourself before you begin

  • Close any open windows. Wind or draft may bring microorganisms that can contaminate the Psilocybe cubensis 'Golden Teacher' Magic Mushroom grow kit.
  • When taking out the grow box with the cake from the carton box, put it on a disinfected surface. If this surface would not be clean, microorganisms may attach to the grow box and will flourish inside the Psilocybe cubensis 'Golden Teacher' Magic Mushroom grow kit and will contaminate the grow box.
  • Make sure you work with clean hands and arms. We recommend using surgical gloves or a good disinfectant when handling the kit. You should use a facemask to avoid breathing into the grow bag and on the cake.

Starting the process

  1. Fill the box with fresh, potable water. Close the grow box well and let it soak for 12 hours.
  2. After 12 hours, pour the surplus of water out of the grow box.
  3. Place the grow box inside the grow bag. The open end of the bag should point upwards.
  4. Remove the lid from the grow box. Rinse the lid and store it in the carton box.
  5. Fold the open end of grow bag twice; do not cover the micron filter.
  6. Place the paperclip on the fold, so the bag stays closed. Now the Psilocybe cubensis 'Golden Teacher' Magic Mushroom grow kit is ready to grow.
  7. Place the Psilocybe cubensis 'Golden Teacher' Magic Mushroom grow kit inside the carton box, on top of the ziploc with lid.

The ideal temperature is 24°C. Do not have the temperature drop under 18°C and not exceed 29°C. To keep the temperature from dropping under the 18°C, you can use a Thermo Heatingmat to maintain the ideal temperature. A thermo mat is a must-have in the winter or colder regions of the world.


The Psilocybe cubensis Mondo® Golden Teacher Magic Mushroom Grow Kit only needs light for the mycelium to ‘understand’ it has reached the surface. Only then, mushrooms will grow. A few hours of fluorescent/artificial light or indirect sunlight a day is more than enough. Direct sunlight kills the mycelium, so avoid the sun to shine directly on the grow kit.

Water / Misting

The day after you start the process you begin with misting. Open the grow bag by removing the paperclip. Do not spray directly on the cake but spray one time against every side of the bag. So you mist once a day, four sprays. Misting also vents fresh oxygen inside the bag. Right after misting, close the bag again with the paperclip.


If the conditions are optimal, you can expect the first small mushrooms (the pins) to appear between 5 and 16 days. This also depends on the strain. Some cubensis strains grow slower than others.


The mushrooms come up in groups. This can be a small or large group. That depends on the strain. A growth like this is called a flush. Mushrooms are almost never ripe at the same time. You can get more than one flush out of a kit. The first two flushes are the largest. When more flushes come, they will be smaller than the previous one.


Mushrooms are ripe and should be picked when the veil between the hat and the stem has just torn. Don’t wait much longer. Use surgical gloves or disinfect your hands, wrists and arms. Pick the mushrooms that are ripe and let the others continue to grow. Remove the mushrooms from the cake by taking hold of the base of the mushroom between thumb and index finger. Rotating your hand clockwise slowly, until the mushroom lets go. Do not pull out the mushrooms. This would risk damaging the mycelium and killing it. When most of the larger mushrooms have been picked, also pick the smaller ones and the pins as well.

Mushrooms that grow from the sides

Mushrooms grow where the light reaches and where there is little penetrating resistance. Because the cake has light shining on the sides, the mushrooms might also grow there. It is hard to counter this and can be allowed. Some growers wrap the sides of the grow box in aluminum foil to keep the sides dark, but this doesn’t always work well.

When mushrooms grow there, they can be picked just before you soak the kit:

Clean hands! Take the grow box out of the bag and place it upside down on your other hand. Wiggle the plastic box so that the cake will fall out, onto your hand. The plastic box can be placed on a disinfectant surface. Now you have this hand free to pick the mushrooms from the sides of the cake. When all mushrooms are picked, you can place the cake back as it was, in the plastic box and continue to the soaking process.


After all the mushrooms have been picked, you prepare the kit for the next flush. Again, with disinfected hands or gloves; take the grow box out of the grow bag. Fill the box with fresh, potable water. Take the lid out of the ziploc bag and use it to close the grow box. Place the closed grow box in a soaking Bag or use your own clean plastic shopping bag and wrap it around the box. Close it well and place this in a refrigerator (2°C to 8°C) for 12 hours. This is called the soaking process. Water will now soak through the cake, preparing it for the next flush.

During the soaking you can hang the grow bag with micronfilter upside down to dry. Make sure to hang it upside down, so no microorganisms will access the bag. Many growers prefer to use new and unused grow bags after every flush.

After 12 hours take the soaking Bag with the grow box, out from the fridge and unpack it.

Next Flush

To continue, follow the same steps 3 – 7 as before when you started the process for the first time. Several days later, a new flush will appear. You can get at least 2 or 3 flushes out of a Psilocybe cubensis 'Golden Teacher' Magic mushroom grow kit. If you are experienced in cultivating, you can get more flushes out of a kit.

The end

When no more mushrooms grow out of a grow kit after the second flush for at least three weeks, or when the Psilocybe cubensis 'Golden Teacher' Magic Mushroom grow kit turns green, red, grey or yellow; the grow kit can be disposed of.  The change in color is a sign that the grow kit is contaminated with another fungus or bacteria. No more mushrooms will grow out of the Psilocybe cubensis 'Golden Teacher' Magic mushroom grow kit and the grow kit should be thrown away in the garbage outside.


When you are too late picking the mushrooms, they will drop their spores. The cake and the mushrooms will turn black/purple (some other cubensis strains red/brown) because of the spores. This is not really a problem; it just doesn’t look very pretty. When mushrooms release their spores, they also start to degrade, and the active ingredients are breaking down. Mushrooms will lose some of their potency.

First flush yelded 15 grams of dried fruit. Excellent product, very fast shipping, nothing to complain, higly recommended Review by Elle (Posted on 9/10/2021)
No good
I received the normal kit as a replacement for the XL one which turned out to be dead. This one started a little better but in the end provided no mushrooms at all. Same conditions as McKennaii and B+ kits I've been using and those two gave plenty of shrooms. Maybe it's a bad batch or just bad luck, but I'll be avoiding these for now. Review by Alma (Posted on 6/11/2021)
Good product
Good product, it continuously grew and it was difficult to separate the flushes in my case. It gave 3 flushes, not as large as with B+ but interesting one Review by Mark (Posted on 6/5/2021)
Complete disappointment
I have had multiple GT kits ordered so far. After carefully following instructions and long care, every single one eventually failed to grow any mushrooms. Although the customer service is usually kind enough to send a replacement, it usually ends the same way. I gave up at some point. Never had problems with other strains from the shop, only GT. Waste of money and time this time :( Review by Grzegorz (Posted on 5/21/2021)
no signs after 4 weeks
I ordered one kit of Mckennaii and one kit of Golden Teacher. I followed the exact instructions for both of them and I was very careful. I already got 2 flushes on Mckennaii after 4 weeks, but the Golden Teacher kit gives no signs and I am disappointed about it.
I also sent 2 emails to denounce the problem, but I got no responde back about this and that's not nice

Great service
Great kit Review by BB. Kiddo (Posted on 5/14/2021)
Great customer support and very satisfied with the kit
First pins appeared on the 16th day. The first flush gave 96gr (8 dry) and the second flush yielded 81 gr. Very good potency. Now waiting for a third flush. The customer support was always fast and helpful throughout the whole process whenever I had questions. Overall the kit and the shop gave great experience. Review by Emil (Posted on 4/28/2021)
Hard to say
I have received an invitation to review today.

The customer service people bare helpful and knowledgeable as always. So far I do not have many mushrooms after a month or so. Some small pins appeared about 10 days ago, but they stopped growing. Yesterday the guys advised me to give it a cold shock to try and kick start it, so fingers crossed it will start today.

I have found the team to be great and have had great success with two of the 5 boxes I have tried. I want to make it a 3/5, so fingers crossed this one gets moving. I had some problems with two boxes before (other varieties, but the team replaces them swiftly with no problems, I just hope they have a better hit rate elsewhere or else they have a problem in their business, but when they work, they are great kits. Things are quite variable. I had two small kits provide over 600g fresh each (Amazon and B+) I had a Mexican that grew only two mushrooms and stopped and a MCKaennai that only grew a few long spindly pins and produced very few. I really want this Golden Teacher to come on and grow now, it will be the one that decides whether to order from them again in future. The team are great, but if the product is going to be so variable, it's hard to put their staff and myself through the 50/50 bet that it has been so far. I give a 4 because the service is great and the product is great when it works, and maybe I have done something wrong, although if I have, nobody can say what it is and my temp control and other conditions have been very well controlled . If this one doesn't grow either though, I will have to seek out a more reliable source.

Amazing support
I couldn't make the kit grow, I suspect choosing this strain didn't help. The support team has been very helpful and, after explaining the situation, I got a new kit I'm growing right now. Than you guys Review by Lucio (Posted on 12/15/2020)
Amazing support
I've been having troubles in growing my first kit, I assume choosing the Golden Teacher strain contributed. After describing the situation the support team decided to replace the kit. Thank you guys. Review by Lucio (Posted on 12/15/2020)

Great customer service
Very good customer service as they helped me a lot through the process. I finally had 2 good cycle and I'm going to try the third one now. I recommend! Review by great (Posted on 4/27/2020)
Lost parcel
My parcel got lost in the delivery for about 130 euros.
This company won't even write a reclamation to justify me to the parcel company.
They sent owe me anything but if they write a reclamation I get my money back from the parcel company.
I don't understand why you don't help your customers when problems appear !
All you have to do is just write to them and everything's fine ?!
Review by Marcel (Posted on 4/24/2020)
three weeks and nothing showing...
I ordered the Mondo and the Fresh Mushrooms "Golden Tops" kits at the same time for comparison. I have followed the instructions exactly as state on the respective pdfs (available on the website) for both grow kits.
I am still waiting for Mondo to show any signs of life
Fresh Mushrooms are already finished with a bountiful round one and awaiting a second.

MMS Edit: When there is no growth, please contact our customer support with pictures, so we can offer advice.
Review by Greg (Posted on 4/14/2020)
First time - great
When I've received the kit it took almost a month for something to happen, after that it's flush after flush on a weekly basis.
Now I'm on my 3rd, every time there are more mushrooms than the previous time.

The only problem I had is that they started growing from the sides, but after placing the cake vertically there are no problems. Just a bit contamination due to my mishandling - it is my first time.
Review by Kristjan (Posted on 11/20/2019)
