Magic Mushroom Grow Kit Treasure Coast XL by Mondo®

The Treasure Coast XL grow kit will grow you a large amount of potent magic mushrooms. The first flush is lacking in quantity but the next flushes will give you lots of shrooms and will continue to do so flush after flush.

Occasionally the Treasure Coast sprouts an Albino mushroom. A real potent treasure to have in every spore collection.

The journey the Treasure coast muhsrooms gives is a deep spiritual and one if you let them very visual.

Product Description

Years of planning and testing has resulted in the next generation of Mondo® Treasure Coast XL magic mushroom grow kits. The  Treasure Coast 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® Treasure Coast 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
  • 1x reusable yellow seal – 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® 'Treasure Coast' 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® 'Treasure Coast' 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 reusable yellow seal on the fold, so the bag stays closed. Now the Mondo® 'Treasure Coast' XL Magic Mushroom grow kit is ready to grow.
    7. Place the Mondo® 'Treasure Coast' 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® 'Treasure Coast' 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 reusable yellow seal. 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 reusable yellow seal.


    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® 'Treasure Coast' 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® 'Treasure Coast' 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® 'Treasure Coast' 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.

    Sehr zufrieden Review by Janis
    Hatte bisher keine Probleme damit solange man sich an die Anleitung hält gutes growkit! (Posted on 6/11/2024)
    Hoch interessant! Review by Paul
    Nach 1 Woche Anzucht kam es zum ersten, sehr üppigen Flush. Daraus hatte ich inzwischen zwei ausgewaschene Trips erlebt, und ich habe etwa nochmal soviele Pilze getrocknet. Der Flush will und will nicht stoppen.
    Heute nahm ich, 95 kg schwer, gegen 9.38 Uhr etwa 25-30 getrocknete und in Staub zermalmte Pilze mit etwas Wasser und einer halben Banane ein. Bereis nach 20 Minuten erlebte ich einen heftigen Trip und legte mich in einem abgedunkelten Raum hin. Besonders die sensorische Seite war ausgeprägt. Mächtige Euphorie — ich hatte das Gefühl, jemand haut mir auf meine Dopamintaste mit aller Wucht darauf. Zeitgefühl verloren. Immer wieder musste ich mich an das Atmen erinnern, denn der Körper sah darin wohl keine Notwendigkeit mehr.
    Kurz nach 13 Uhr war alles mehr oder weniger schlagartig wieder vorbei.
    Vielen Dank für dieses tolle Erlebnis! (Posted on 1/8/2024)
    Good yield, potent mushrooms Review by SF
    So far I got 800g wet out of the growkit in three flushes. Currently waiting whether there will be a fourth one.

    While I had another Treasure coast growkit in the past, the mushrooms from this kit are much more potent. I wonder whether the hotter weather has made it so.

    I think I have been less careful than I could have been in keeping contamination away from the kit. My impression is, that the kit is quite resilient.

    Also, customer service is very responsive. I kept nagging them with stupid questions and needless worries and got a timely response every single time.

    So, thanks so much in giving us easy access to these wonderful substances that offer so much healing potential for all of us! (Posted on 9/6/2022)

    Lovely mushroom! Review by Liep_li
    Really nice, potent, feel good mushroom, worked well in a club also - ate just a pinch for fun but they turned out to be stronger then i thought :)
    Tried: golden teacher, amazonian, cambodian, red boy and mexican and these may be my favorite.
    Will order again! (Posted on 2/10/2018)
    Contaminated Review by Norm
    The box did start to smell of mold after 10-12 days and after 21 days nothing was growing and I found mold and had to throw it away. Customer support registered the contamination report more than a week ago and even after I wrote them again nothing does seem to happen. Thanks. (Posted on 2/7/2018)
    good Review by Tanex
    Good stuff - buy scales ! (Posted on 12/29/2017)
    Avoid this box ,,,, Review by Ayoub
    This TC xl box is the worst i've had ever ...
    After 2 successful, very successful grow with panama and PES amazoniac , I decided to go for TC XL as i was intrigued by the albino spin off. Bad choice ! the first box got contaminated ! i thought it was my mistake so ... swallowed the loss and ordered another one ... made sure to be 100% protected using sprays and alcohol. and guess what ... It got contaminated again !!! and the customer service people are really into defending their company even through lying rather than apologizes and fix the issue !!!
    Bottom line avoid this box ... maybe even the whole shop ... still waiting for their feedback will keep you posted how it goes

    Edit by MMS: We have had email contact with this customer, but we could not get to an agreement or understanding. (Posted on 3/16/2016)
    T C Review by Phil
    Gut. Sehr potente Pilze. (Posted on 8/19/2015)
    Fantastic Review by Nya
    I has previously tried both B+ and Golden Teachers from this site, however I wasn't prepared for the strength of these guys.

    I took 3.5g dry on an empty stomach, I noticed strong visuals coming on within 30 minutes. I was seeing fairies that kept offering me candles and it was a lot of fun at first. However it got so strong I wasn't able to navigate or hold a conversation, my thoughts went inwards and I experienced being a god consciousness which was actually pretty frightening as I hadn't planned on a level 5 trip on such a small dose out in public !

    So just be cautious if you're trying these and take at least a g less than you usually do.

    As for growing, I had one contaminated box which mms replaced within 2 days to the UK, fabulous customer service! All the other boxes are growing well, they are small mushrooms but there are literally 100s growing, they just don't stop.

    A new favourite of mine but I'm not taking more than 2g next time lol (Posted on 8/15/2015)
    Super colonization Review by Starling
    Ok, I got an email to review this so I will. All I can say so far is that this 2 liter box I placed carefully without direct sunlight in a dim place. The thermometer that came with it I plunged in the middle of the box and helped me understand that the temperature without a heating mat was more or less precisely perfect hovering about 24 degrees C. Now I have the whole surface blooming with very small fruits, it's wonderful to watch. I'll report back with trip reports, but I suspect these little beauties are going to be very strong...
