Product Description

Years of planning and testing has resulted in the next generation of Mondo® PES Amazon XL magic mushroom grow kits. The  PES Amazon XL grow kit is now even better than it ever was. Compared to the first generation of Mondo®XL magic mushroom 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 Mondo® PES Amazon XL magic mushroom grow kit is slightly different than the grow kits you may have used before. These are mainly 'under the hood' differences and are not easily seen.

Just like the previous and other easy mushoom grow kits, you do not need to use additional spores. During the laboratory process, the spores have developed in mycelium inside the substrate (the cake) in the grow box.

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 after productiondate. 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 large grow bag – The bag has micron filters to keep contaminants out
  • 2x 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 to use


    How to prepare the room and yourself before you begin

    • Close any open windows. Wind or draft may bring microorganisms that can contaminate the Mondo® 'PES Amazon' XL 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, micro organisms may attach to the grow box and will flourish inside the Mondo® 'PES Amazon' XL 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 is 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 large 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 ziplock bag for later use. Place the ziplockbag with the lid back in the carton box.
    5. Fold the open end of large grow bag twice; do not cover the micron filter.
    6. Place the paperclip on the fold, so the bag stays closed. Now the Mondo® 'PES Amazon' XL Magic Mushroom grow kit is ready to grow.
    7. Place the Mondo® 'PES Amazon' XL Magic Mushroom grow kit inside the carton box, on top of the ziplock 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 mat to maintain the ideal temperature. A thermo mat  is a must-have in the winter or colder regions of the world.


    The Mondo® 'PES Amazon' XL 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 large grow bag. Fill the box with fresh, potable water. Take the lid out of the ziplock 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 micro organisms 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 Mondo® 'PES Amazon' XL 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 Mondo® 'PES Amazon' XL 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 Mondo® 'PES Amazon' XL 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.

    Helpful Service
    My first box was a delayed delivery and subsequently the cake turned green and fruited no more than 10g in total. Received a free re-ship and the customer service was fast and friendly Review by Maia (Posted on 6/19/2019)
    Fast delivery. Easy, productive and fast results.
    Delivery - fast.
    Growing - fast, productive (50 - 60g), easy
    Effect - strong but short.

    Did not pay that much attention on growing process. I assume the harvest could be bigger if I would be more accurate.
    Review by Jānis (Posted on 5/24/2019)
    Fast delivery. Easy, productive and fast results.
    Delivery was very fast. Same for growing :) did not need to pay too much attencion.

    Got around 60g, but I could get much more if I would fallow instructions.

    Effect - strong but short

    Fast delivery. Easy, productive and fast results.
    Delivery was very fast. Growing as well he he. Shrooms do not request to have lot of attention while they grow.
    Effect - powerful but quite short (of course that is idividual)

    Would recommend to everyone
    Super fast shipping, kit contaminated during first flush with green mold, great customer service - sent a replacement which was perfect and resulted in high yields. Very satisfied, can't go wrong with this shop! They are legit! Review by Great (Posted on 2/7/2019)
    Awesome Review by Sara (Posted on 1/26/2019)
    Really good results and experience
    I've purchased this strain multiple times already, because I read it's one of the stronger ones and has great yields. It is exactly as described, really strong kick, can get a nice high from 1-2g dried or just float off if you take 4-5g. The feeling is great, it makes you a bit hyperactive with the will to explore, but that may vary from person to person. I've always had around 6-7 flushes, with about 25-30g dry for the first 4 flushes, then it slowly started dropping. After the 7th flush, there were only a few smaller mushrooms that grew, so I didn't bother, because I already got enough stored up.

    All in all, an excellent strain, very recommended!
    Review by Miha (Posted on 1/20/2019)
    Nevertheless, Thanks
    Box turned out to be contaminated.. At first it took a long time to pin and mature. They did grow even though contaminated.. to bad I have to throw them.away. They lookwd healthy overall but I wont enjoy them. Will get another box for sure. Review by Traveler (Posted on 1/19/2019)
    Mushrooms galore!
    We have just harvested an abundant crop off these Amazonian beauties! And they keep on giving. Yet to sample their magical qualities, but the shades of blue they are producing during the picking and drying process indicates masses of the good stuff! I'm confident I will be back for more, and have recommended the product to friends already! Review by Mermicorn (Posted on 1/13/2019)

    Good product, even better service
    We got this growkit as a substitute for another, which had arrived moldy due to hot temperatures in August.
    The customer service was incredible - within a short time we were able to start with a fresh box that yielded great mushrooms.
    Highly recommended!
