Magic Mushroom Grow Kit McKennaii by Mondo®

The McKennaii Magic Mushrooms are a tribute to Terrence McKenna. They might be even stronger than the popular, but challenging mushroom to cultivate, Hawaiian (Copelandia cyanescens). No doubt the McKennaii Magic Mushroom Grow Kit grows one of the strongest cubensis listed in our magic mushroom catalog. McKennaii is for the more visually interested.The shape, size and color of the Mckennaii can change with every flush.

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 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 '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.

Read, download or watch the instructions for the Mondo® McKennaii magic mushroom grow kit.


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 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)
Five out of five... plus one Review by Bob
Best experience so far with the kit and the customer service!
Very fast delivery: 3-4 days since payment registered. This is the fastest I've had comparing with others.
Quick growth, easy to maintain but you need to be patient and careful with basic hygiene. I've had the first pick within 14 days for 40g fresh. First flush gave 210g in total in 19 days - awesome! :) Second flush gave 280g so almost 500g fresh in two flushes. now I'm at 3rd flush which seems to grow more slow but I think it's because I left it soaking for 12h instead of 24h (btw: the soaks were 24h each from the start).
Really potent for me, had really nice and strong trips with as low as 1.3g dry but I've tried 4g too as I like exploring :)

A really good recipe I've refined: dont eat for at least 6h, avoid greasy junk food to keep your digestion light for optimum psilocin metabolizing (I think )). Grind to fine powder and leave it in lemon juice for 40-60 mins (60 mins means strong tripping after 20-30 mins. Mix with a room temp herb tea of: chamomile (half of spoon), artichoke (half of spoon), caraway (1 tea spoon), marjoram (half of tea spoon), honey. Tea made at max 90C (better at 80C to avoiding being too bitter from the artichoke.

This is definitely where I'll order from now on for sure!
Highly recommend to try all of the above :)
Have a good trip! (Posted on 6/3/2021)

Two months and nothing grows Review by Leonor
Hi there! Well I ordered this kit around February and the package was as it is described. I was super excited not only for the mushroom experience but to be able to grow them my self. I followed all (and I mean ALL) of the instructions, including keeping it nice and sterile but since the last day when you put it in the bag nothing grows .. I'm just disapointed .. Moreover I sent an email to the customers support and no one replied .. Don't think I will be purchising any more kits from here..

MMS EDIT: We tried to reach out to come to a solution, but there was no reply. When issues like this arise, please contact us at [email protected] (Posted on 4/12/2021)
Very good! Review by /v
I got this kit a month ago and I am very happy with the results. The creatures grow nicely and didn't have any issues with contamination. They are still growing btw. I am not always soaking the kit, the little fellas grow at different speeds so I pick up the ones that are ready and leave the rest when possible (sometimes many come out of the same stem and this is not possible but on other occasions, it could be done). If there are small ones that I left out then I just continue to spray the insides of the bag and they grow like mushrooms ; ). And new ones also appear. If I pick all of them, then I soak. I find this works best for me. Recommended. Will get another batch may be different one after I finish with this kit. (Posted on 4/9/2021)
A strain full of surprises... Review by Afonso
This strain is really full of surprises, if the kit goes well all is good and the effects are very nice, maybe one of the best. But if the growing part doesn't go can be a bit disappointing. So take good care of your kit. (Posted on 3/26/2021)
Everything worked perfectly! Review by Yareru
I was worried while buying these I would kill the mushroom before it even has a chance to grow. But the kit was well prepared and everything worked out perfectly. I have about 90 grams wet on my first flush. Can't wait to try it out! (Posted on 3/17/2021)
Slow grow, but powerfull fruits Review by L.o.
Delivery was within expected time and well packed. Followed the online instructions (open bag for fresh air once a day, mist every other day), left the cake inside the carton box and used the heating mat that I also ordered as it was in the middle of winter. Nothing happened in the first week, so reading reviews a lot of people were saying to mist it more often and also open bag for fresh air more often, so that's what I did. So another week goes by and nothing happens. I then decided to take everything out of the carton box and saw that one side of the substrate was a bit yellowish and that worried me (which later I would find out it can be a natural response from the mycelium being old or stressed), but I also had a few side pins. A couple of days later there were a dozen of side pins and they continued to grow on the sides even with the carton box and only one or two very small mushrooms grew at the top of the substrate for the whole first flush. So by the time I had to pick the first mushrooms, around 7 days later, I had immense difficulty doing so, as many of them were coming from the bottom of the substrate, completely squeezed by the plastic box, so I had to take the whole cake out of the plastic box in order to be able to get the mushrooms. As the majority of the mushrooms where coming from the sides, I just decided to go ahead and put the cake on a shotgun fruiting chamber. The substrate was very dry in the middle when I took it off, probably because of the heating mat, even though I left a space between the mat and the box with the substrate as recommended, maybe that's why I had no fruits at the top of the substrate.

Anyway, in the sgfc the mushrooms continued to grow quite slowly, decided to end first flush about two weeks later, ended with a bit less then 90 g

For the second flush, already got several pins from the start but they took way too long to grow, could be because I could not keep the room temperature above 18C. So I managed to get only around 60g on this second flush and unfortunately, at the end, the substrate got contam with trich and I had to toss everything.

For a first time definitely a nice experience, this strain is also quite potent, nothing to complain on this. (Posted on 3/16/2021)
No growth on top but moderate flush on sides Review by Juraj
Well, I followed the instructions but for some strange reason no growth on the top but rather on the sides (I took a photo of it). First flush was not very rich... anyways, I will try again. I don't blame anyone as it is nature, things happen... the only question is if the kit needs to be exposed to light (not direct sunlight of course) or it needs to be with less daily illumination... that is not clear to me. Cheers! (Posted on 3/13/2021)
