Magic Mushroom Grow Kit B+ by Mondo®

Grow your own B+ magic mushrooms with the Mondo® Mycelium kit. Without a doubt the Bee plus is one of the largest of all cubensis mushrooms in our collection.

Perhaps the B+ Magic Mushroom grow kit is even the most resilient. Stories are not uncommon of people disposing the substrate in the garden after it has been exhausted only to find B+ magic mushrooms growing at the same spot the year after.

The B+ psilocybe cubensis is a great beginner strain for cultivation and exploring new dimensions !

Product Description

Years of planning and testing has resulted in the next generation of Mondo® B+ Magic Mushroom grow kits. The Mondo® Grow Kit B+ has become better than it ever was.

Compared to the first generation of Psilocybe cubensis Mondo® B+ 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.

How to store your mushroom 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.

Contents of the B+ Psilocybe Cubensis Magic Mushroom kit

  • 1x grow box – This contains substrate with active mycelium (the cake) of the B+ cubensis strain
  • 1x grow bag – The bag has a micron filter to keep contaminants out
  • 1x 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 using

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 'B+' 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, microorganisms may attach to the grow box and will flourish inside the Psilocybe cubensis 'B+' 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 it 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 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 carton box.
  5. Fold the open end of 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 'B+' Magic Mushroom grow kit is ready to grow.
  7. Place the Psilocybe cubensis 'B+' Magic Mushroom grow kit inside the carton box, on top of the ziploc 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 Heatingmat to maintain the ideal temperature. A thermo mat is a must-have in the winter or colder regions of the world.


The Psilocybe cubensis Mondo® B+ 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 grow bag. Fill the box with fresh, potable water. Take the lid out of the ziploc 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 microorganisms 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 'B+' 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 'B+' 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 bacteria. No more mushrooms will grow out of the Psilocybe cubensis 'B+' 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.

5 years worth of therapy in 5 hours...
What can I say more than mushrooms are your very good friend even in a difficult trip. The delivery of this growing kit was swift and the people I emailed got right back to me... This particular strain grew well until it grew some mould in the corner which was my fault so I am giving 5 stars and am just about to order again. Thank you x Review by Linn (Posted on 11/11/2020)
As a first-time grower I am pretty sure I did everything you are not supposed to and this growkit is on the third flush. Would recommend. Review by Nudlika (Posted on 10/23/2020)
Great learning experience!
I recently became interested in mycology & spirit, and a friend recommended I turn to your site for guidance & supplies. I ordered the Mondo B+ & Golden Teachers, as they are indicated to be good starting varieties for beginners. That was great advice. It is so much fun taking care of the grow kits, watching them develop and feeling so rewarded by amazing harvests (436g in two flushes for the B+, with a third flush underway). I am learning so much from out friends the fungi, and would like to encourage all to read Merlin Sheldrake's "Entangled Life" to enrich their learning experience along with the hands-on growing experience. I am deeply appreciative! Review by Patrick (Posted on 9/29/2020)

One of the best experiences ever
Those mushrooms were amazing and they grew fast.
It was very grounding and it got me in touch with my essence in an incredible way. I totally recommend this website and those mushrooms.
But hey guys from Magic Mushroom Shop, last time I ordered it didn’t work and you said you’d give me another kit.. I never got it! But just to remember and it won’t affect my appreciation towards the shop and the products! You’re great! Thanks.

I am very pleased that I ordered this product Mondo® Grow Kit B + ,I am very pleased that I ordered this product, following the instructions by the end of the third week, I noticed the appearance of the first babies and a week later I harvested the first crop of 170 raw mushrooms, dried them a number of interesting experiments)), after the second wave was 180 grams, and it is already ripening the third one, so I'm very inspired that I ordered another cake in two larger sizes. I advise everyone to try these wonderful creations, they help us a lot) following the instructions by the end of the third week, I noticed the appearance of the first babies and a week later I harvested the first crop of 170 raw mushrooms, dried them a number of interesting experiments)), after the second wave was 180 grams, and it is already ripening the third one, so I'm very inspired that I ordered another cake in two larger sizes.

went wrong
I took me 7 weeks to get my first flush (that i harvested too early), the room's temps can go from 17°celcius to 26°. Since a small week The smell of my kit is no more the same and i see another mycellium taking the lead. It got contaminated at some point. So only one small flush.
