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.

    Najlepsze :D Review by Sebastian (Posted on 11/22/2018)
    recommended strain

    Recommended but sensitive to humidity, everything is fine after the first flush. The "cake" was placed in a larger box after the first flush and it made a difference (up to 4)
    Review by Tom (Posted on 11/15/2018)
    Great results
    1st flush took a little longer to start than expected, however, 2nd flush came in quick, with a bigger yield as well, just started my 3rd flush today.
    I dried them out and made a tea and ate a few... very nice trip... head and body trip with nice visuals... very uplifting, happy trip, very easy to grow, with great reliable results and fun trips... ticks all the boxes!
    Review by Alan (Posted on 9/25/2018)
    Very good experience
    Slow to start off but very nice results. Only got about 30g dried from the first flush, about 45 from the second and I have just started the third. Amazing effects, I've never felt like I didn't have a body before! :-) Review by Louis (Posted on 9/8/2018)
    Amazing PES Amazonian XL. A bit slow to receive the first flsushes but overall very good. We had an amazing trip with the right feelings. One of the best ever Review by Lulas (Posted on 8/27/2018)
    Very high yield also gave the the greatest experience of my life, I've tried a number of different types of mushrooms and these are the best by far Review by Junior (Posted on 8/27/2018)
    Out of the kits I have tried, this for me was the best. Highest yield, most flushes, largest mass, and most pleasurable trips. Can't go wrong with these ones, especially for beginners Review by Christos (Posted on 8/18/2018)

    Review by Rad (Posted on 5/14/2018)
    Great Product!
    Fast shipping, no issues getting the order. Great KIT and one of the best mushrooms! Amazing strong effect and easy to grow mushrooms! Recommend! Review by Vladimir (Posted on 3/3/2018)
    Big fruits, highly resistant to contamination, good trip
    The kit was slow to start off, as it took almost 2 weeks to start fruiting (not very strange, considering that at the time the package arrived the mycelium hadn't colonised the substrate fully).
    The harvests were ok, the 1st one yielded 380gr, the 2nd 190gr, the 3rd 50gr and the 4th 40gr. That is a total of 660gr of fresh mushroom.
    The effects were good, similar to those of Ecuatorian also sold on this page, and stronger than those of B+ and McKennaii (also from this shop).
    What I liked the most is its strength against contamination.
    Review by Ramon (Posted on 2/2/2018)
    Infected kit supplied/ no customer service response
    My kit was slow to start off considering I’ve grown with kits like this before however I waited patiently for the first signs of life. Two weeks in small mushrooms started to show. They continued to grow to maybe an inch tall when green mould then started to appear around the side of the kit. I waited a further 2 days to see if the shrooms would grow any more which they did not. The website informs this scenario is signs of a contaminated kit. I relayed all applicable information back to The website but had no response. Overall disssapointed. Poor customer service.

    PES Amazonian XL Kit
    Great kit,loads of very large shrooms.
    Effects wise I personally prefer these to B+,they seemed more visual.
    Highly recommended ,and as always ,great service /fast dispatch.
    I must say,if you take the time to read up on Mycology,it really is very interesting,McKennaii and Jamaica P. cyanescens are next on my list ,grown from spore vials (also from these guys).

    WOW that was great guys i love you :D, im not sure when im gonna eat them but i just got my first yield picked, the first mush that was shown was HUGE, i dont have scale right now but its seems like about 70 grams. The hole box is filled with mushes and they come new ones growing every day. Review by An di (Posted on 7/29/2017)
    Good Stuff
    As with the other two grow kits I've bought here, this kit yielded a very healthy amount of shrooms.

    The high was ridiculous. My stomach ached for two days afterwards, just from laughter.

    Magic Mushrooms Shop are a perfect specimen of a retailer. Professional, friendly and efficient.

    The customer service are very accommodating and knowledgable.

    Highly recommended.

    Greetings : Holgi

    Review by Holger (Posted on 10/10/2015)
    Slow but potent mushrooms
    There was nothing growing inside my box for like 3 weeks, but then the shrooms decided to fill up the box. I got a great yield out of the first box, it flushed 5 times already and everytime the little devils are just as strong as the former ones. Currently waiting for my second PES box to give me what i want, already seeing those little ones growing big. Review by Satisfied Customer (Posted on 7/12/2015)
    Incredible company & product. Sent cash by post and got super fast delivery. I started at the end of March 2015 and so far I harvested 8 flushes with a total of 924g (fresh) mushrooms. I am curious to see if and how much more will come... It's important to work very clean! After every start it just took about 6 - 9 days to harvest.

    I am speechless! The effect is outstanding with very visual trips. I just can recommend this product to every psychonaut!
