The Mondo XL magic mushroom grow kits do not come with an instruction manual, but this can be downloaded here for free.

Years of planning and testing has resulted in the next generation of Mondo Psilocybe cubensis XL magic mushroom grow kits. The standard Psilocybe cubensis XL magic mushroom grow kit is now even better than it ever was. Compared to the first generation of Psilocybe cubensis 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 Psilocybe cubensis XL magic mushroom grow kit is slightly different than the grow kits you might have seen before. After opening the carton box you will see it right away. In the middle, on top of  the plastic lid you the familiar micronfilter. But new on the lid is a white adhesive strip. Both parts were needed in the first stages of the preparation process in the laboratory. They should remain untouched.

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 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. 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 Psilocybe cubensis 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 Psilocybe cubensis 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 Psilocybe cubensis XL Magic Mushroom grow kit is ready to grow.
    7. Place the Psilocybe cubensis 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 Psilocybe cubensis 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/a>. 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 Psilocybe cubensis 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 Psilocybe cubensis 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 Psilocybe cubensis 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.

    If it fails its your own fault, and it really isnt difficult, they are just epic, everytime. (Posted on 12/31/2017)
    Excellent customer service, not so excellent growing experience Review by Daniel
    Cannot fault the customer service what so ever. Ordered three of these, and yielded about 8 mushrooms from the 3 boxes. The 2 boxes of GT didn’t produce anything at all, even after following the advice given to us from customer service. They advised my set up etc was ok. I have heat mats that turn on/cool down when the temp drops below 23 degrees, and have grown kits from another provider successfully who has recently stopped shipping to the UK.

    Customer service sent me 2 new boxes after everything they suggested failed to work. Its now been about a month, and still not even a sign of a single mushroom in the GT. I don’t know if its the time of the year or something? But i’ve had no success what so ever.

    Again, cannot fault the customer service, the speed of the delivery etc, and the shrooms obviously grow for most hence the good reviews.

    Unfortunately, I didn’t have that success.

    Thanks (Posted on 12/26/2017)
    Sideways Review by Razzle Dazzle
    With the heating packs, the boxes seem to be workin ok....1 box had 1st flush pretty dicent but a lot of shrooms stayed small (not fully grown)....other 2 boxes' 1sr flushes werent so large....and im just starting a second flush....all i can really say up to now is that mushrooms almost only grow from the side where they are squeezed against the box and get crowded with others and they dont have much space to grow in that crack between a cake and a box....would be nice if there is a solution to this? Or so they would grow more from the top of the cake...? Also I must say it is my first time cultivating so i'm a rookie...tho i follow the instructions...Hmmm....but the mushrooms that grow work just fine ;) (Posted on 12/17/2017)

    Xl kits Review by Matt
    Unfortunately when I ordered the 3x xl kits, they turned up and two of them were half white/yellow half blue and obviously had been colonised by some other bacteria, this was before opening the boxes, the last box seemed absolutely fine, but after a day or so the blue/green appeared and that went in the bin as well. This is my 1st experience with the xl kits so I went back to the original and all has been well with them, don’t know if it was a freak accident or the larger kits are packaged differently but they weren’t very helpful! £100 odd wastes if I say so (Posted on 12/10/2017)
    Excellent comme toujours !!! Review by CHRISTOPHE
    Cette fois ils sont tous bien donnés avec un minimum de 5 flushs et 7 pour les B+ qui en moyenne ont donné 2 à 300gr frais par flush. Je n'ai jamais obtenu jusqu’à présent autan de flush de qualité que depuis que je commande chez Champ Magic et j'ai 50ans et pourtant ce n'est pas mon 1° site ni mon 1° essai mais là je suis comblé, donc je repart pour un tour !!! ;-)
    Bonne continuation, à toutes et à tous et soyez prudent !!!
    Cordialement, tof ;-) (Posted on 9/12/2017)
    Perfect as always Review by Lars
    Last time I ordered six of the B+ XL Growkits. As expected, they arrived fast and the quality was great. I picked the first shrooms about three weeks after receiving my order and the kits grew shrooms for 4 months. In total I picked about 500g very potent mushrooms (dried).

    Will order again and look forward to try some new strains :) (Posted on 7/23/2017)

    +++++ Maz@tapec +++++ Review by Mr_Happs
    I usually go for 3x Mazatapec XL and find the kits reliable with great results.

    I Just harvested all three's first flush and got 51 dried grams which i'm very happy with.

    More to come and I'm sure another order to be placed again soon!

    Always the right choice Review by Dieter
    I already ordered the Combi Pack XL four times and were more than satisfied every single time.
    Usually I pick about 150g dried Mushrooms per kit, in 4-5 months. But this time the Clima was not ideal, so I only got about 250g dried Mushrooms from all three kits and had mold after two months. A heating mat would probably have helped..

    I am going to order this Combi Pack again, because the Kits have a very high quality and the support is very nice :)

    Recommended for beginners and also more experienced growers. The kits do not need much attention and the Mushrooms were always super potent! :) (Posted on 2/3/2017)
    Amazonian Pes XL combo pack Review by veps
    Very satisfied, great yield and potency. Also tryed Panama SupaGro kit - grows faster, but less potency. Cambodian XL kit are also good, but amazonian seem to be more potent. Fast delivery and great customer support! (Posted on 1/17/2017)
    a little disappointed Review by Psilocybin
    Red Boy:

    Needed around 23 days to show the first pins.
    Very large shrooms but very few. Only got 7 out of it.
    3 days before I harvested the last shrooms, dark greens (almost blue) mold was growing on top of the cake.

    I got ~17g dried

    Golden Teacher:

    First one to show pins. Alot of shrooms but mostly small ones (mostly under 1g dried)
    Also grew mold a little later after the Red Boys (maybe should've evacuated them).

    Got ~15g dried

    Trip on ~1g dried GT (was the first shroom I picked):

    Made tea, lightly boiled the shrooms for 15 min. Had used too much water so I had to drink alot plus I ate the shroom as well.

    Very dmt like visuals, had contact with ayahuasca (the entity) very heavy body load and very 2D if you know what I mean.
    Was way more than I expected from that one little shroomy.


    Got very large and alot of shrooms out of this box. Developped a little blue spot on the surfice at the very beginning. Thought it was mold, but this kit seemed to be most resistent whatsoever.

    0.7g dried B+:

    Let it sit in the juice from 1/2 Orange + 1/2 Lemon for 30 min, then put the concoction in a pot with a little water and made tea.

    Onset was very quick, maybe 20 min.

    Felt even more intense than the GT trip I had before. Got a new tapestry the day before with a huge beautiful mushroom on it and I was just looking at it morph and step out of the picture. Was a very spiritual experience and I could go very deep. Was also most of the time very 2D but if I focused enough I could get past the threshold sometimes and everything was even more intense and 3D.

    Got ~24g dried


    I disenfected my hands and arms up to my elbows everytime I touched the bags or misted them. Used the gloves I had to pick them, exept for one time and avoided open windows before I opened the bags. Additionally I always used the face mask so I wouldn't breathe into the cakes.

    Now I only got 1 flush out of 2 boxes and they got infected, which I can't explain with all the precaution. And also there is a possibility that the B+ is also infected because I saw some mold on there too but it was so light, that I thought I'd try to flush it 1 more time.

    [edit MMS]Hi, thanks for your extensive review! If you ever spot some contamination on your grow kits, please contact our support with some pictures and we'll figure out how we can help you there. :) (Posted on 11/24/2016)

    I had great results with all the varieties I ordered. All flushed again and again producing fruits of good size and potency. Brilliant value. I am ordering again today. (Posted on 9/17/2016)
    Works fine. Review by Mikkel
    Had six of these xl kits, and they have produced several kilos of wet material, most doing well over 10 flushes, some got bad, and only gave only a couple of flushes. Can only assume it was a sanitary issue by my own mistake.

    Will buy again. (Posted on 9/15/2016)
