The Redboy is a mysterius mushroom strain. That has crimson spores and may grow to be very large. Read on for an unusual comment about the strain made by a well-known shroom user:

Monokaryotic Puerto Rican mycelium crawled over non-germinating 20-year-old redboy spores in a laboratory dish, resulting in a 50/50 cross between the redboy spores and the PR mycelium, with the original spores never germinating because they were no longer capable of doing so after 20 years.

After the agar had cooled, rattlesnake venom was administered to weaken both the spore and mycelium cell walls, allowing the nuclei to exchange genetic information. The procedure was repeated with the offspring, resulting in the appearance of a 75% pure strain.

The latest generation of Mondo® Red Boy XL magic mushroom grow kits is the result of years of research and development. The Red Boy XL grow kit is now more powerful than ever. The second generation of the Mondo®XL magic mushroom grow kit outperforms the first in the following ways:

  • Greater harvests and mushrooms
  • More flushes*
  • Increased ability to fend against infections
  • Not the same, but simpler directions* More flushes are produced by certain strains than by others. The biggest flushes occur during the first three.

Reach the next level of grow kit simplicity.

There are a few minor differences between the grow kits you may have used in the past and the Mondo® Red Boy XL Magic Mushroom Grow Kit. The majority of these are “under the hood” variations that are difficult to notice.

As with the earlier and other simple mushoom grow kits, more spores are not required. The spores have grown in mycelium inside the substrate (the cake) in the grow box during the laboratory procedure.

How to store the grow kit correctly

It is advised to begin the cultivation process as soon as possible. If you choose to begin growing later, you can keep the grow kit for two weeks following the manufacture date in the refrigerator (2°C to 8°C). Initially, place the grow kit into a plastic shopping bag and securely seal it.


  • 1 grow box, which includes substrate with live mycelium (the cake)
  • 1 large grow bag with micron filtration to prevent impurities out
  • Two paperclips are needed to seal the grow bag.


You need

  • Misting Bottle: Misting is required based on the relative humidity.
  • Distilled water: For soaking and sprinkling
  • Maintain a clean workspace to prevent the contamination of other fungi and bacteria (micro organisms).


We recommend to use

  • Surgical gloves
  • Facemask
  • Disinfectant for hands
  • Disinfectant for surfaces
  • Soaking Bag
  • Thermometer
  • Thermo mat (when room temperature drops below 18°C)


How to get ready before starting: both yourself and the space

  • Seal off any ajar windows. Microorganisms that could infect the Mondo® Red Boy XL Magic Mushroom Grow Kit
  • Place the grow box with the cake on a sanitized surface after removing it from the carton box. Microorganisms may stick to the grow box if this surface is not clean, grow inside the Mondo® Red Boy XL Magic Mushroom Grow Kit, and contaminate the grow box.
  • Make sure your hands and arms are clean when working. When handling the kit, we advise using surgical gloves or a good disinfectant. To prevent breathing onto the cake and into the grow bag, wear a facemask.


Starting the process

  1. Add potable water that is fresh to the box. After securely closing the grow box, let it soak for twelve hours.
  2. Pour the extra water out of the grow box after 12 hours.
  3. In the huge grow bag, place the grow box. The bag’s open end ought to face upward.
  4. Take off the grow box’s lid. After giving the lid a good rinse, put it in a ziplock bag to keep it handy. Reposition the ziplock bag with lid into the carton box.
  5. The huge grow bag should be folded twice, but the micron filter should remain exposed.
  6. To keep the bag closed, place the paperclip on the fold. Growing mushrooms is now possible with the Mondo® Red Boy XL Magic Mushroom Grow Kit.
  7. Inside the carton box, place the Mondo® Red Boy XL Magic Mushroom Grow Kit on top of the ziplock bag 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.


Light is all that is needed for the mycelium in the Mondo® Red Boy XL Magic Mushroom Grow Kit to “understand” that it has reached the surface. Mushrooms will grow only then. It is more than sufficient to have a few hours each day of indirect sunshine or fluorescent/artificial light. Avoid letting the sun beam directly on the grow kit as it may kill the mycelium.

Water / Misting

You start with misting the day after you start the procedure. Take the paperclip off to open the grow bag. Spray once against each side of the bag rather than directly onto the cake. Thus, you mist four times a day. Additionally, misting allows new oxygen to enter the bag. Use the paperclip to reclose the bag as soon as it has stopped misting.


In five to sixteen days, if all goes according to plan, the first little mushrooms—known as pins—should start to appear. The tension affects this as well. Certain strains of Cubensis grow more slowly than others.


The mushrooms appear in clusters. This group could be tiny or large. Depending on the tension, yes. This kind of growth is referred to as a flush. It is rare for mushrooms to be ripe all at once. A kit can be used for multiple flushes. The greatest flushes occur during the first two. More flushes will follow, but they will be smaller than the first.


Picking mushrooms when the veil between the hat and the stem has just torn indicates that they are ripe. Do not delay any longer. If possible, wash your hands, wrists, and arms. Wear surgical gloves. Select the ripe mushrooms while leaving the others to grow. Grasping the mushroom base with your thumb and index finger, you may remove the mushrooms from the cake. Gently turn your hand clockwise until the mushroom releases its hold. Never remove the mushrooms by hand. This could potentially harm or even kill the mycelium. Once the majority of the larger mushrooms have been harvested, proceed to harvest the smaller ones along with the pins.

Mushrooms that grow from the sides

Where there is less penetrating resistance and light penetration, mushrooms flourish. The light beaming on the sides of the cake may encourage the growth of mushrooms. This is difficult to argue against and is permissible. To keep the edges of the grow box dark, some growers wrap aluminum foil around them, but this isn’t always effective.

There are mushrooms that can be plucked right before the kit is soaked.

pristine hands After removing the grow box from the bag, invert it onto the palm of your other hand. To get the cake to fall onto your hand, wiggle the plastic box. You can set the plastic box on a surface that has been cleaned. You can now pick the mushrooms from the cake’s sides with this free hand. Once every mushroom has been harvested, return the cake to its original location within the plastic box and proceed with the soaking step.


You set up the gear for the following flush once all the mushrooms have been harvested. Remove the grow box from the large grow bag using clean hands or gloves. Add potable water that is fresh to the box. Remove the ziplock bag’s lid, then use it to shut the grow box. The closed grow box should be wrapped in a clean plastic shopping bag or placed inside a soaking bag. Put it in the refrigerator (2°C to 8°C) for 12 hours after tightly closing it. We refer to this as the soaking process. The cake will now be saturated with water, readying it for the subsequent flush.

You can hang the grow bag with the micronfilter upside down to dry during the soaking process. Ensure that it is hung upside down to prevent microorganisms from entering the bag. After each flush, many growers would rather use brand-new, unused grow bags.

After 12 hours take the soaking Bag with the grow box, out from the fridge and unpack it.

Next Flush

To proceed, carry out steps 3 through 7 exactly as you did the previous time around. A fresh flush will emerge a few days later. Mondo® Red Boy XL Magic Mushroom Grow Kit will yield at least two or three flushes. A kit can yield more flushes if you are an expert cultivator.

The end

Grow kits can be disposed of after the Mondo® Red Boy XL Magic Mushroom Grow Kit turns green, red, grey, or yellow, or when no additional mushrooms sprout out of them after the second flush for at least three weeks. The grow kit may have become contaminated with bacteria or another fungus as a result of the color change. The Mondo® Red Boy XL Magic Mushroom Grow Kit is finished and should be tossed outside in the trash. No further mushrooms will grow from it.


When you are too late picking the mushrooms, they will drop their spores. The cake and the mushrooms will turn black or purple (some other Cubensis strains are red or 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.

    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..
