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.

    mediocre flushes
    The first flush was 182g, second 64g, now growing the 3rd one doesnt seem to be much more. Review by Radovan (Posted on 7/13/2020)
    Very good
    Made tea with ginger, lemon and 4 grams magic..
    One of the best trips I've had. No nausea, no stomach
    Ache and intense visuals.
    Sadly only one flush of about 180g then got
    Contaminated.. Also it only grew around the edges
    Review by Sean (Posted on 6/14/2020)
    Not bad
    So its nice flush but weaker than Golden teacher.... Review by kate (Posted on 5/26/2020)
    Good staff
    To get more shrooms I'd ordered an XL kit, but I got the same overall harvest as with Golden Teacher XP by FreshMushrooms.
    Managed to get 2 flushes. The strain itself is excellent.
    Going to try it again.

    If its about amount- it was am explosion! From first shot i had a full oven ???? it was majestic view. I still didnt try the mushrooms other way than microdosing and this causing me to be little sleepy but it's not relayable. I hardly recommend! Review by Radoslaw (Posted on 5/20/2020)
    Amazing, thank you!
    Hi, got approx 275g fresh from first flush. Tried a small dose first time to get to “know” the strain an potency. Great introspection, lots emotions and insights. John Hopkins playlist was perfect company while sittimg on top of a hill with a beautiful view.
    Thanks for a super product!
    Review by Samuli (Posted on 5/16/2020)
    My box didn’t work
    I followed the instructions and after 3 weeks still nothing, then the box became mouldy, I waited still 6 weeks later not a single mushroom. I have to say I was very disappointed as it’s pretty exspensive and I was super excited to see my batch grow but got zero.

    MMS Customer support: When a kit does not grow, it's always good to contact us as soon as possible (within 21 days).
    Review by Tropics (Posted on 5/6/2020)
    Very nice trip and yield !
    I have been growing different kind of strains but this one resulted in the biggest yield ! Around 700g fresh which resulted in 65g dry, total 5 flushes . Also the duration of the trip was longer compared to other strains for example B+.The only disadvantages, when using XL boxes it takes much longer before you can harvest 3-4weeks. For the smaller size this only takes 2weeks but much less yield. So go with the XL :)

    Definitly will try this strain again but first the golden teachers !
    Review by Jeroen (Posted on 4/18/2020)
    Nice mycelium growth, but the plastic paper clips are not cool because they like to break and plastic is already shitty so why not normal metal paper clips? Review by Sven (Posted on 3/18/2020)
    I am really surprised with this shrooms. You guys made excellent job with this growing kits. This is my first time I bought PES Amazon shrooms and they are awesome. The kit gave me seven flashes: 202g+130g+225g+178g+178g+141g+70g Unbelievable!
    The trip I experiences after 4g dried shrooms was excellent. Very strong visual effects and 5 hours cosmos journey :) Once again: five stars product!
    Review by Zencooler (Posted on 2/27/2020)
    Great growing & trip experience
    After being disappointed with grow kit from different supplier I decided to try this shop and at the end I'm more than happy. After 3 weeks time grow kit packed with shrooms and trip also very nice. Second flush is on the way. Definitely worth my reccomendation. Review by Witold (Posted on 2/15/2020)
    Seems OK
    This Mondo XL Amazon PES kit took quite some time to grow (3 weeks over a heating mat before we started to see the first pinheads) , but that soon-to-be 1st flush seems pretty decent. I'll try to make un update about how the other flushes grew and how te trips actually went Review by Cedric (Posted on 1/28/2020)

    Mondo® Grow Kit PES Amazon XL
    Potency as usual - much over the average, but with lower temperature (below 24 celsius) I got into some weird issues. At a temperature of over 24 degrees they grow brilliantly. As soon as the temperature drops (even by half a degree), the mushrooms fall asleep. This time I started growing with a temperature of 23 degrees. The first mushrooms appeared after about 4 weeks and were small, growing very slowly and there was very few of them. When it warmed up and the temperature rose to 24.5 degrees, the mushrooms got kicked and were able to grow large overnight. Either it's a matter of a specific growkit, or 24 degrees for PES is not the ideal temperature, but basically the lower limit at which they normally start to rise.

    Excellent quality, fast growing, rich flushes
    Compared to the Golden Teacher (which was my first order here) PES gave larger flushes. It was easy to grow (I extended the refrigeration phase to 24 hours - to give the spores a good kick - Golden Teacher did not want to grow after three weeks and then I was told that keeping it in the fridge a little longer could help "wake up" the mushroom. And it did. So this time from the beginning I let the spores lie longer in the fridge. I didn't experience any problems with PES - it grew quickly (a week or so) and gave 4 large flushes. Compared to GT they are probably a little stronger - but it can be a subjective impression. You certainly get more and bigger flushes than I got with GT. Fast delivery and good quality. I can only recommend Review by fifth element (Posted on 9/3/2019)
    worked well
    This was my first growkit ever and as a newbe I am sure I didn't do everything perfectly right. But the results were very nice and the effect of the mushrooms pleasant. I couldn't get a second flush because I went on a trip (by car) and couldn't take care of the growkit. I'll try the next time. Review by Mina (Posted on 8/9/2019)
    So far, excellent
    When these were delivered I put the parcel straight into the fridge as I was travelling for 9 days.

    It took a further 14 days from set up to the first flush which yielded 140g. I put the kit in the bag into the carboard box it arrived in to try to discourage growth from the sides and it seemed to work.

    These were strong. I took 70 wet grams and tripped for 7 hours. The trip was deep and profound. I'm looking forward to the next flush!
