Product Description

Years of planning and testing has resulted in the next generation of Mondo® McKennaii Magic Mushroom grow kits. The Mondo® Grow Kit McKennaii has become better than it ever was. Compared to the first generation of Psilocybe cubensis Mondo® McKennaii 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® McKennaii 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 mushroom 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.

Contents of the Mckennaii Mushroom Grow Kit

  • 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 'McKennaii' 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 'McKennaii' 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 'McKennaii' Magic Mushroom grow kit is ready to grow.
  7. Place the Psilocybe cubensis 'McKennaii' 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® McKennaii 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 'McKennaii' 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 'McKennaii' 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 'McKennaii' 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.

Mckennai love Review by Nikos
I have tried several times to grow mushroom kits. Mckennai i think has the best overall from all. Extra potency and harvesting. With many harvests. Sometime it can reach even 8 harvests.
It has happened to me. I love this quality.
Everybody should try it. (Posted on 6/21/2022)
Everything was fine! Review by Mate
Everything went flawlessly according to the descriptions.
Helpful sellers.
Thank you! (Posted on 6/16/2022)
McKennaii Review by N
Easy to take care of them. I had continuous grow for about 2 months and then got contaminated (my fault), but overall it gave great results.
When consuming in large doses (about 6-7 grams) I had very weak visuals but the philosophical side was very strong.
You definitely learn a lot about yourself on this one :)

all good, Review by jack
and customer suport is just so kind, thank you! (Posted on 6/11/2022)
Easier than I first anticipated. Review by Rob
Initially, I was very skeptical regarding my abilities to operate a growkit; I am quite easily distracted and often kill my own plants due to forgetfulness and neglect. However, I found the entire procedure both straight forward and rather joyful. Be patient and prioritize hygiene, and your harvest shall be plentiful! (Posted on 4/8/2022)
Fast arrival and greate yield Review by Jānis

Really fun experience Review by Ugnius
I took fresh 15 grams and it was quite fun experience for me. I thought that I will have something more but it was actually very very relaxing and fun with a lot of laugh experience (Posted on 1/27/2022)
Mckennai Review by Elliot
Really good place to buy growboxes from. (Can recommend McKenna strain. Really good and potent)
The only negative i can come to think of is that that
They don’t use bubble plastic to wrap the product.
I’ve ordered McKennai. The first box came with the lid open,
Could have been the customs or just a bad job.
I’ve spoken with support and they sended me a new box.
Unfortinatly 2nd box came damaged, the plastic holder was broken.
I mailed the support and still waiting for a new one to be delivered.
I also have Mexican cubensis that I’ve ordered. Haven’t tried them out yet but they look really healthy and good. My first flush gave me around 14g dryed. The mushrooms are big and tall.

Another negative thing is that some “strains” have been out of stock for a very long time. I’d love me some golden teacher. But haven’t seen them being for sale for at least a year now.
Besides this, is a really good plug ;)
Will definitely order more.

It is nice Review by Niels
Got it as a replacement.
Made about ~40g dry in 2 flushes. After that it got contaminated unfortunately. It was maybe my fault not sure but it is still nice.

Very good vendor with very helpful staff :)

great but not so great Review by mark
Great mushrooms and I loved growing them. It was easy until I tried my second flush. Nothing happened except a lot of mould growing instead of mushrooms. I asked the seller why but was told to wait. It's now three weeks and it's not going to happen. Unsure if I've done something wrong but I had a great first flush so not sure what went wrong. (Posted on 11/16/2021)

Goooood Review by H

very dissapointed Review by Laurenz
I ordered this set with Mondo PES Amazonia and FreshMushrooms B+. Both Mondo (McKenny and PES Amazonia) sets began 1 day after soaking to mold but I worked sterile. The B+ was a nice harvest after 2 1/2 weeks but the rest seems like it didnt work. I worked like in the instruction written but it just didnt work.

Very interesting and pleasing to grow strain Review by Aga
The first flush about 14 days wet 133 grams of mushroom caps were small but very nice when they started to grow mushrooms I moved to a plastic box 300x300x300 with three holes of 30x40 one on the lid two sides nicely plugged with cotton from the pharmacy also spray stenite, but not everyone day airy is better and began to melt faster, on the second flush I took the cake out of its box and again put in the plastic box immediately on the second day I had small mushrooms on the side and most were on the sides the second flush hats are also very sweet in different from the first flush and bigger if I could upload a photo I would upload it I think as an idea to be able to upload a photo, but let the moderators decide that my second flush was 168 grams wet, and at the moment I have a third flush for now I microdose in two days at 0.340 I will increase slightly and I will reach larger doses in two or three months, but my efficiency is increasing I have and change I want things around me to be in order I like the change and each person may be different, but everyone decides for himself what to do.
I am satisfied with the site and the service.
I highly recommend.
Good luck to all. (Posted on 7/15/2021)
Mondo® kit de cultivo McKennaii Review by Hugo
É a segunda vez que compro o kit.
Desta vez comprei 2 para conseguir maior quantidade.
já fiz 3 colheitas e consegui cerca de 100g, estou à espera de uma 4ª.
Relativamente à trip...depende bastante da quantidade...mas já consumi 5g de uma só vez e obtive uma trip bastante visual e intima.
Uma das trips mais belas que já tive com nuvens estão vivas pessoal....hahahaha (Posted on 7/7/2021)
Good kit, nice crop Review by Al
Ordering and delivery simple and quick. The mycelium looked a bit different and so I sent a photo to support - they immediately replied that all was OK and just to continue. They were right - I have had two excellent flushes already and am awaiting the third. Only had a little nibble to test, but seems like a fun mushroom trip - am looking forward to trying a bigger dose soon. (Posted on 7/7/2021)
