Golden Teacher Supagro Grow Kit with 100% colonized substrate

The Golden Teacher is called as such because 1: the gold color of the caps and 2: its' shamanistic properties. Golden Teacher Magic Mushroom Grow Kit grows large mushrooms with wide-rimmed caps. The yield is large, despite the fact that the first flush is generally smaller than the second. The GT psilocybe cubensis started to appear in the late 80's but their exact origin is unknown.

The substrate of the myceliumboxes by SupaGro is 100% colonized. More mycelium means more mushrooms!

Product Description

The Golden Teacher magic mushroom grow kit is a product of the SupaGro company. This company redefines the way magic mushroom grow kits are produced. A whole newly developed method of producing these Golden Teacher magic mushroom grow kits has been developed. This has resulted in magic mushroom grow kits that can proudly wear the name: SUPA!

When comparing Golden Teacher SupaGro magic mushroom grow kits to the standard magic mushroom grow kits, there are differences you should be aware of:

  • The first two flushes are Supa Large! Up to 300 grams per flush*
  • The first flush comes faster. First results can be expected after only a few days.
  • Substrate is 100% colonized by mycelium.
  • Very contamination resistant.
  • A totally new designed SupaBag with venting holes. The substrate with mycelium (also called cake) really needs to breath.
  • No layers of vermiculite on top and no perlite on the bottom.
  • The lid has venting/expansion holes.


SupaGro Grow Kits look different than other grow kits

The Golden Teacher SupaGro magic mushroom grow kit is different than the grow kits you might have seen before. After opening the carton box you see it. In plastic lid, eight holes were drilled. These holes were part of the production process.

You might have received a Golden Teacher SupaGro magic mushroom grow kit with the lid partially opened up. Sometimes this happens during transport. This is caused by a combination of the production process on one hand and the mycelium trying to expand on de other. When the mycelium is so well developed, it might push the lid up creating small openings. Don't worry, when this has happened, just continue with the procedure. The mycelium is so strong and well developed by now, contaminants well have a hard time to infect your Golden Teacher SupaGro magic mushroom grow kit.

Don't test this by not working hygienically. We recommend always using surgical gloves or a good disinfectant when handling the kit. You should use a facemask to avoid breathing into the SupaBag and on the cake.

The SupaBag has holes

The SupaBag has two rows of holes. The top row is to let the oxygen in and the bottom row is to vent carbon dioxide out. There is no need to open the bag for ventilation as you might normally do with the standard grow bag with microfilter. When the SupaBag is placed correctly, this allows an optimal respiration gas balance for the mushroom growth.

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 Golden Teacher SupaGro magic mushroom grow kit inside a Soaking Bag in the refrigerator (2°C to 8°C) for 6 weeks.


  • 1x SupaGro grow box – This contains substrate with active mycelium (the cake)
  • 1x SupaBag – The bag has 2 layers of punched holes for ventilation.
  • 2x paperclip – For closing the grow bag.


You need

  • A Misting Bottle 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.

How to prepare the room and yourself before you begin


Starting the process

Do not soak the grow kit! This is not needed at this stage.

  1. Place the grow box inside the SupaBag. The open end of the SupaBag should point upwards.
  2. Remove the lid from the SupaGro grow box. Rinse the lid, dry it and store it in the carton box for later use.
  3. Fold the open end of SupaBag twice; do not cover the venting holes.
  4. Place the paperclips on the fold, so the bag stays closed. Now the Golden Teacher SupaGro Magic Mushroom grow kit is ready to grow.
  5. Place the Golden Teacher SupaGro Magic Mushroom grow kit inside the carton box, on top of the lid.



The ideal temperature is 24°C. Do not have the temperature drop under 18°C and not exceed 29°C. SupaGro does not recommend using an heating mat with their magic mushroom kits. Using a heating mat is at your own risk, no guarantees can be given.


The Golden Teacher SupaGro 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

Misting should be started with on the day that the first mushrooms (pins) appear. Open the grow bag by removing the paperclips. 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 but only when the mushrooms are visible. 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 10 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. The cake has no top layer such as vermiculite. This makes is much easier to pick the mushrooms than with the standard grow kits. The mushrooms can easily be pulled out of the cake by holding them between thumb and index finger. They mushrooms let go almost immediately. 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 SupaBag. Fill the box with fresh, potable water. Take the lid out of the carton box 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 SupaBag upside down to dry. Make sure to hang it upside down, so no microorganisms will access the bag.

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 1 – 5 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 large flushes out of a Golden Teacher SupaGro Magic mushroom grow kit. If you are experienced enough in cultivating, you can get more flushes out of a Golden Teacher SupaGro Magic mushroom grow kit. Up to 8 flushes!

The end

When no more mushrooms grow out of a grow kit after the second flush for at least three weeks, or when the Golden Teacher SupaGro 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 a bacteria. No more mushrooms will grow out of the Golden Teacher SupaGro 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.

Only a few succesfully grown shrooms :(
I am a little bit disappointed in this Growkit. It grows me only o few shrooms from the side (inside of the box between the mycelium and the box) and the rest of the grow kit got moldy after a lot of days.
Maybe I do something wrong or the grow kit somehow defected, but I have totally only a 5g of shrooms from it. [MMS Edit: Check out our blog and FAQ for tips and tricks what to do when this situation occurs with your growkit. Magic greets, MMS Team ]
Review by PH (Posted on 2/15/2019)
Only got a spattering of mushrooms around edge
My kit definitely looked a lot different to the picture on the site. I only had a few mushrooms growing around the edges and after three flushes they didn't amount to much.

I have checked with the company that the crop I got and the fact I didn't get a single mushroom in the middle is acceptable and they have confirmed this is normal.

Not many mushrooms for the amount of money

fast growing awesome ! Review by ludnicawawawa (Posted on 1/16/2019)
Growing very fast, harvested about 17 days from opening the box. Reliable, robust, second flush works too. Very easy for beginners, like me! Review by Mateusz (Posted on 1/5/2019)
I am very happy to have the opportunity to grow Golden Teacher Grow Kit. It is very simple and easy to grow this kit and after three weeks I manage to collect proper amount of mushrooms from the first flush. Thanks. Review by Jaketa (Posted on 12/5/2018)
First flush was massive. Not much bare substrate when harvested. Almost all mushrooms. They also seem to be more resilient against contaminants than the standard grow kits. There's also less hassle when cultivating compared to standard grow kits. Review by Fred (Posted on 10/20/2018)

Thank you for great customer service
Thanks for replacement. Nice yield, going to test soon. Review by Marius (Posted on 8/7/2018)
The guys at MMS are super helpful and quick to respond!

We ordered 2 Golden Teacher kits, one of which was severely contaminated and failed to grow anything. They were kind enough to replace the kit pretty swiftly! The replacement kit grew amazing harvests.

The second kit produced very small harvests. Possibly partially contaminated also as the mushrooms only grew in a few patches.

Mushrooms themselves produced minimal visuals but amazing mental clarity and focus; perfect for microdosing!

Thanks guys! xoxo

Kit Came Contaminated
Unfortunately, the SupaGro kit came contaminated with mold on the surface and it smelled sweet when i opened it (which tells that the kit isnt alright).
I feel bad because i lost the money.
I had a beter experience with the other kits and won't order the SupaGro again, i guess,



[mms edit: Hi Kevin! Could you please contact customer support so we can solve the problem! Please send us photos of your kit. ^IQ]
Review by Klueman (Posted on 7/22/2018)
First time successful
First time growing and the whole process was fun and very simple! We are now waiting for the third flush and already got around 40g of dry mushrooms!
Before the first harvest we flushed the tank with water even tho it said not to (bc we didn’t read the instructions on time) and we thought that it’s gonna be a problem, but so far it seems ok.
Just had a small testing and the effect is very nice :)

Thank you! Very smooth grow and brilliant for micro dosing. Review by Irene (Posted on 6/6/2018)
Got a problem but service solved it quickly!
I ordered some GT and got a problem with ma Boxes, I decided to contact the service and clarify my point. The service response was quick and nicely. I ordered over the years from other shops, but never had this friendly and good support. Im very happy to found a shop with a good customer service and fast support. So I can't give less than 5 stars, because the problem vanished and im happy with the service here. Review by Trippin'Shaman (Posted on 5/14/2018)
Great kit, easy to use. First time grower, got 4 flushes and no contamination, I was very careful with cleanliness. Total of 445g wet, dried out to 39.5g in a dehydrator. Flushes went ; 215g after 16 days/ 155g after 8 days/45g after 8 days/ 30g after 7 days.
More potent than I thought they'd be and I'm also using them for micro-dosing.
They're also good fun to grow, I really enjoyed the whole process.
