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.

    Good Times are over.. Dont Order Here anymore Review by Acidic
    Total Rip Off.. Been A Customer for 7 Years from you orderin Tons of kits every Month and never had any Problems at all, but my Last Big Order was the biggest Rip Off ever.. I cannot believe how you guys Changed. Sold me more the 25 Kits which were used before or something without any Yield at all, Looking old and moldy. Quality is ridiculous now.. I cannot believe you sell these Trash Kits now without any bad conscience..Thank you for all the years of Work together but its over for me here.. lost about 1000bucks to Shit this time and my trust is gone now... Back in The day you wouldve never done this but now u got corrupted or something .. Karma is watchin you tho always never forget that.. thanks for the Past years of good work but iam out now for good.. U just lost a bomb Customer..
    Adios (Posted on 4/7/2020)
    Poor quality Review by John
    the mushrooms grew only on the side, not on top, and the yield was also poor. poor quality colonies were obtained. we never buy anymore from here.

    [mms edit: sorry to hear that John! Sometimes the toplayer of the substrate is compressed due to the rough shipping. We suggest to put the bricks on there side inside the plastic container in the grow bag. This way the mushrooms can grow from the sides and even from the bottom freely and you can enjoy a high yield. We hope to see you back with us! ^IQ] (Posted on 4/5/2020)
    Poor quality Review by centaurium
    The mushrooms were only willing to grow sideways and with relatively little yield. I will buy elsewhere in the future!

    [hi centaurium, sorry to hear that do not have a good experience. Please note that mushrooms love to grow in an easy way. The top layer might be difficult for the mushrooms to penetrate due to compressing during shipping. You can put the brick upright inside the plastic container (and in the grow bag ) so you give the mushrooms more space to grow from the sides and they can grow freely. Hope to see you again in our shop! ^IQ] (Posted on 4/1/2020)

    Amazing website Review by Vlad
    I have ordered from this site 2 times and both times I was completely satisfied. Both times I had a mouldy box which was kindly replaced. The first time I got three boxes I grew at least 150g dried which is more than satisfying for me. Currently growing another set of boxes and it is looking good so far. Highly recommend!

    Kits are awesome & customer support is legit af Review by Martin
    Have been client for something like 3 years already. Grow kits are great and easy to care for.
    If you order, I would recomend you to replace paperclips with clips for clothes, that would be more convenient for every day misting.
    Customer service is the best, had issue with cakes but they resolved everything. Like seriously, this is as legit as it gets.
    My yields vary between cakes. For example one cake got me 69 g's, other 84 g's. (Posted on 1/2/2020)
    Excellent Review by Michael
    Fast delivery. First flush from 5 boxes and I've got about 1.25kg. Next flush looks like it's going to be at least the same. Amazons. I'd give a 5 star but we always have room to improve. (Posted on 12/27/2019)
    great customer service, express delivery Review by Peter Pan
    XXL grow kits are great value for money. In my last order, one of the kits got infected with black mold that spread to others in short time. Guys at the shop replaced all three kits, which I greatly appreciate. Certainly the way to go. (Posted on 12/23/2019)
    Exellent!!! Review by MagicYagé
    I am customer more then one year and after I have
    discovered Xxl growing kits I am more then satisfied!
    They are giving massive yields if temperature is good
    and if you follow procedure. From one kit is possible
    to get more then 1kg of fresh fruits which is more then
    good for this price. Keep going MagicMushrooms Shop!
    Delivery is always fast and with no sign that grow kits
    are inside. Even with payment this shop has different
    name which makes payment more secure.
    Thank you,Thank you, Thank you!!! (Posted on 12/6/2019)
    Excellent value for money! Review by Andro
    Red Boy always deliver and XL boxes are my favourite. A bit longer time to start, but yield is always high and shrooms are very potent.
    One thing that separates your company from others is an excellent costumer service, filled with great advices and understanding towards any problems that might occur. If you haven’t, try this and I promise you wont regret it! (Posted on 12/5/2019)
    7 years a customer an then treated like a doormat. Review by jaymc
    I received the kits with the Mycelium not fully formed inside kit. I noticed when I first got them (ordered 3xl's not cheap)... I used to receive kits with white all the way round the sides... Looks like these were rushed out the door.

    I was hoping it would be ok, normally I see a lot more white all around the tub, but these ones only has patches of white Mycelium.

    I am now fruiting but the yield is not good enough, they are coming up in patches here and there.

    I have never complained to customer service about not getting a good product from them in all of my 7 years buying from this I have to say the support experience I am having is very unpleasant... Even argumentative.. I was met with scepticism and attempts to shift the blame elsewhere....

    I quote "You've mentioned having 7 years of no complaints at all. Some would argue that this is exceptional"

    yeah but I have a complaint now !

    and also: "Well, we don't produce the kits, we have a supplier for that. "

    As if to say not our fault ? I don't care who produced them I purchased them from you right HERE !

    "If you don't want to send pictures, we can understand that. But we won't have visual support and proof for the complaints."

    So even after seven years they don't believe me think I am making the hole thing up. I am not to keen on taking an sending incriminating pictures, but I guess I may have to, it's not even about the money for me at this point tbh I don't care I'm just upset with the company. I wasn't even going to bother writing this review but to be honest... it is just not good enough.

    It's typical when a place get busy the customer service goes out the window...

    Telling me they don't make the kits (not our fault like), telling me I should be happy cause I had no complaints until now. What a thing to say to me, a loyal long term customer ?

    I am disheartened, I really liked this company you know I don't want to go somewhere else but now I am loosing my respect for my old an previously good kit source. I think someone is taking shortcuts somewhere. Quality is not what it was. I wish they could of just handled situation better bit more diplomacy and understanding, appreciation for my business would of been nice. Obviously they don't care or appreciate my business anymore...

    This is what happens when place gets busy customer service goes down unfortunately.


    [mms edit: Sorry to hear you feel unheard. Especially since we are still in the process of finding a solution together and giving support to your slow growing grow kits. ^IQ] (Posted on 11/28/2019)
    Fast growing! Review by Mikkel
    I only completed first flush: One got contaminated. Another started getting contaminated but we scraped the first 2 cm off top layer of substrate. Last one was damaged when we got the mail but it turned out perfect after we ductaped the hole. (Posted on 11/8/2019)
    Was better the first time Review by Jānis
    When I bought individual box the amount and potential was way better. But it could be that the heating season was off at the second time.

    Therefore I'm getting another set to see if the conditions where the guilty ones. If not - I'm afraid I will change my raiting (Posted on 11/6/2019)
