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 reusable yellow seal – 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 reusable yellow seal 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 reusable yellow seal. 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 reusable yellow seal.


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.

McKennaii with massive yield Review by Zed
I ordered McKennaii several times, nearly always works pretty well. If not, customer service helps immediately and send another block for free. Now for me it is under cultivation, and have to say that it will be a massive harvest soon. ???? They sell 1st class products, I encourage everyone to try. (Posted on 12/27/2023)
Everything is perfect. I recommend. Review by wan
Mondo® Grow Kit McKennaii Ban after 14 days the first small mushrooms appeared, the stalks are long first flush 110 grams second flush 100 grams now I will see a third flush.
I have experience with this mushroom, had a sat and two bad trips.
As a tip, first try the strength of the sponge 1.2 grams dry then decide how much you will increase after two weeks of course.
Every trip is different, I don't eat meat for a week before the trip and I do it with half a lemon and a little honey on an empty stomach in the dark with closed eyes. Also put a bottle of water with you, if you remember during the trip, drink water after that, it continues again ,because there is dehydration during the trip.
There is a trip in which it spins you like a water slide and then passes other levels, there is a trip in which it knocks you out and then you go down, the trips are different, they are not repeated.
Another tip I can give you that I tried after a bad trip for two weeks, I took 5-HTP capsules 3pcs a day, a food supplement to increase serotonin levels and then the trip was perfect sometime before the trip about 10- 15 minutes in the dark I look at a lighted candle, then I put it out, take it and wait for the trip with this kind of sponge, time passes quickly, 4 hours pass very quickly, as long as it is not a bad trip, but with a bad trip, inhale and exhale and say to yourself , that everything will pass, breathe in and breathe out.
I wish good trips to everyone, I admire Terence McKenna, he took 5 grams dry in two weeks, but not everyone can reach that level. (Posted on 10/3/2023)

Great kit Review by Wolverine
First flush worked well. Waiting for the second one (Posted on 12/18/2022)
You have to be patient Review by Laura
The kit didn't show much life after 2,5 weeks which made me a little bit concerned about the results. After coldshocking them for a second time the first pins finally started showing. First batch was not impressive, the second one looks a bit better, not sure how many I'll get out of the kit but I am happy at least some babies are growing. I'll have to test them first too. ;-) (Posted on 12/18/2022)
I’m quite excited Review by Maryan
Hi, so this is my first trying and I don’t know what to expect. It’s was so fast delivered and good packed. It’s already one month has done but only 1 mushroom has grown, so I don’t know maybe it’s too cold in a room but I hope everything will be good. (Posted on 11/26/2022)
