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.

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.

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.

incredible insights
after 9 months of psilocybin diet i finally came back home. i am an experienced tripper and i took about 7 gr of this divine thing (it was not that easy to grow, but any second waited worth). impossible however to describe any insight, but i guarantee anybody: it has been defintely my best trip ever: the substance talked loudly and showed anything of the universal fractals we went through. honoured and thankful forever.

Hammer Box!
Hatte mir die Box vor einem Jahr bestellt. Nach 3 Wochen erster Flush. Konnte sie drei mal Flushen

1. Flush 21g trocken
2. Flush 10g trocken
3. Flush 9g trocken

Habs dann auch zum ersten mal gegessen gleich mal 5g probiert(trocken) hatte sehr geilen Lachflash hab mich nicht mehr eingekriegt habe dann Nebel gesehen und die Fliesen meiner Küche haben grün geleuchtet. Am Tag darauf 5,5g ,der Trip hat sich mehr in meinem Kopf abgespielt ich habe mit verstorbenen geredet und bin in Afrika auf Elefanten geritten. Alles wahr irgentwie logisch und ich habe den Sinn der Welt verstanden Gott gesehen und so sachen. Aber ich hatte immer ein sehr gutes Gefühl dabei habe mich sehr wohl gefühlt. Prima zeug kann ich nur empfehlen!

Healthy flush, realised i am the face behind the all seeing, me and my bro laughed like little girls, tears of job, visuals were unreal, my pal seen an angel, will never look at trees the same again. recomend them to anybody, amazing afternoon. 5stars easy Review by Shroomish (Posted on 8/20/2012)
Habe als Anfänger mit dieser Myzelbox nichts Falsch gemacht-verdammt gutes Produkt.Die Pilze des ersten Flushes waren 155 gramm Frischgewicht-der zweite Flush war mit 60 Gramm auch gut,hier waren die Pilze deutlich gößer gewachsen-der dritte Flush brachte nach erneutem Wässern(wie bei jedem ...) noch einmal 92 Gramm Frischpilz,hier waren es die schwersten überhaupt,denn es waren im dritten Anlauf nur !!! 4 Riesen.
Ich würde immer wieder bei dieser Firma kaufen.
Mein wunsch für die Zukunft: ...größere Boxen,hi...
Viele Grüße
Review by Markus (Posted on 5/20/2012)
I ordered McKennai-myceliumbox,it works fine-my first flush was about 170g of fresh mushrooms,now I saw the second flush with 18 very big grown shrooms-they are much bigger then the first flush.
After eating 0,5 gramms dried mushrooms I could feel very nice rushes and a very euphoric feeling.The coloures are very intense-for this low-dose ewperiment a good option to do it again-maybe with one gramm or more!
Very good service,always buying more
Review by Markus (Posted on 5/16/2012)
i have opened gateway to my home...
Never grown before, so i brought 2 kits Mckennaii and Thai.. Now on 3rd crop from each and am amazed with the yield.. As far as their intended purpose.. The fun i had with a select group was amazing and we will play again... Oh Yes!!... However my trips taken solo have been enlightening to say the least.. multi dimentional comunication and an understanding of sacred geometry are just the tip of the iceberg... WOW.. Yeah its probably best it stays illegal... cos i'm so bloody dangerous when i see through the bulls**t and i'm not eating my MSG and flouride dinners...LOL ....Seriously though... Thankyou so much for giving light life and love.. :-) Review by leon (Posted on 1/18/2012)
not very psychedelic!
i ate a lot of them but it was more like XTC, not what i expected, no visual effect at all, a little bit dissapointing. nice without expectations of course Review by goraksa (Posted on 1/16/2012)
What started as a promising kit, turned out as being worthless. A dud.
I ordered a Mckennaii growkit some time ago. i wanted the best of best so i took the mushroom on the webpage with highest concentrations of psilocybin.

as the kit starts to grow an i see dusins of dusins of pins on the substratum soil, i got candlelights in my eyes. but as the day for harvesting comes around and eat the substances. there is almost no action. Only a very light sense of what i recall as being high on weed.

I figure that the psilocybin, perhaps not is flowing through the organisms yet, so i wait and see how the next flush works. I had to eat about 120 grams of fresh mushrooms before i got an effect. And even after that, i had to add some raw hashish. witch i usually never do.

Lets see if things work out a little bit more trippy the next time :)

Kind regards and marry christmas.
Stay tuned

My personal favorite
Now these are amazing ones , i prefer them much better than Amazonians . Grow very fast with heating pads. It always takes me more+less a week to see shrooms starting to grow. Its amazing feeling see them growing every day so fast. I took dry these ones , usualy i make tea from fresh . So intense it was taking my breath away ( in good way ;) ) I start looking at the clouds at some points i start seeing all sky as 5D or 7D point oif view . Very hard to describe it . I saw clouds as as space and then they start growing , breathing , changing colors , shapes :D I couldnt stop watching. A lot of laughts . So peacefull . One of my best trips ever!!!
