Birthing the Cakes

Once a cake is completely covered in white mycelium, wait at least 1-2 more days before taking the cake out of the jar. When you are ready, and in a fairly clean room, begin transferring the cakes from their jars into their fruiting chamber (described in the next step). Remove the lid of each jar, and dump out the dry vermiculite on top. Then, put the lid back over the top of the jar. Slowly turn the jar upside down, so that the cake is resting on the jar lid. You may need to gently tap the jar to knock the cake loose. Take the jar off the top of the cake and then carefully pick up the cake and turn it over, so it is sitting right side up on the lid. Placing down a piece of foil, , put them it into the fruiting chamber. Once all the cakes have been transferred, you're ready to induce fruiting.

Inducing Fruiting (Producing Mushrooms)

In order to initiate fruiting, three main conditions must be met for the cakes:

1. First, they need light. Only a dim light is needed. A fluorescent lamp or indirect sunlight is plenty of light. Mushrooms do not gain energy from the light like plants do, but in this particular species of mushroom light sends a signal to the mycelium that it is time to produce mushrooms. A source with a wide spectrum of light, especially containing lots of blue light (daylight and fluorescent plant lights are very good examples of light with lots of blue) is best, but a low wattage (15 watts is plenty) incandescent light bulb will supply enough light.

2. Second, they need a fairly high humidity. 90-95% humidity is a good range for fruiting. The best and easiest way to do this is by lining the bottom of the fruiting chamber with damp perlite. A common mistake is to get the perlite too wet, and end up with a swamp of water and perlite that is very difficult to clean up, and will drown the cakes. Get enough perlite to make at least 1" (2.5 cm) thick layer on the bottom of the fruiting chamber, and put it into a colander, strainer, or cloth enclosure that it can't slip out of. Wet it thoroughly with normal tap water, and let the water drain out. Then move the perlite into the fruiting chamber and smooth out the surface. You now have a layer of damp perlite that the cakes can be set directly on, and which will keep the humidity in the chamber high enough for the cakes to fruit. By the time your cakes have stopped producing mushrooms, the perlite might start getting a little bit skunky smelling. If you want to reuse it, put it in a baking pan and cook it at 350 degrees in your oven until it is dry. Let it cool, and it's ready to be used again. You can also add some Hydrogen Peroxide to the wet perlite to help it stay clean a bit longer.

3. Lastly, it is a good idea to lower the temperature range a bit, to about 75-80 degrees F. Like the light, this signals the cakes to begin fruiting. However, most strains of Psilocybe Cubensis fruit so easily that lowering the temperature is not absolutely necessary.

    When growing mushrooms how long does a fully colonized cake stay good before transfer?
    1 year ago
  • A fully colonized cake can remain viable for up to 4 weeks or longer if stored in a cool, dry location. If the cake has been exposed to light or heat during the colonization process, it should be transferred to a fruiting environment as soon as possible.

      What is a cake when growning mushrooms?
      1 year ago
    • A cake when growing mushrooms is a cake that is made using a combination of ingredients specifically suitable for growing mushrooms, such as grains, compost, and vermiculite. It provides an ideal environment for mushroom mycelium to grow and develop.

          What is the difference between birthing mycelial cakes and dunking cakes?
          1 year ago
        • Birthing mycelial cakes involves carefully pouring a mixture of grains, such as rye or millet, that have been colonized by mycelium into a sterile container. This container is then sealed and left to incubate, allowing the mycelium to use the grains as a food source and colonize the container. Once the cake is fully colonized, it can be used to inoculate substrate for mushroom growth. Dunking cakes involves submerging a fully colonized mycelial cake into a solution of water and/or nutritive salts, such as calcium, magnesium, and potassium, in order to rehydrate and refresh the cake. This allows the cake to become more active, increasing the mushroom growth rate.

            • Birthing mushroom (also known as birthing root) is a medicinal mushroom that has been used for centuries in traditional Chinese medicine to treat infertility and balance hormones. It is thought to help regulate a woman's menstrual cycle, reduce the symptoms of menopause, and promote fertility.

                When is my mycelium cake ready to fruit?
                1 year ago
              • It depends on the variety of mushroom and the growing conditions. Generally, mushroom grow kits will have a label that states when the mycelium cake is ready to fruit, but it usually takes anywhere from 1 to 4 weeks.

                  What to do if myceliak cakes cant be birthed?
                  1 year ago
                • If your celiac cakes cannot be birthed, you should first contact the bakery or store where you purchased the cakes to confirm that the ingredients used to make them do not contain any wheat, barley, and/or rye, which are all known to trigger a celiac disease reaction. If the bakery or store confirms that the cakes do not contain any of these grains, then you may be able to substitute with a different grain such as rice, quinoa, or oats. If this is not possible, then you should consider baking your own cakes with safe ingredients or purchasing cakes from another bakery or store that specializes in gluten-free baking.

                            Do I need perlite for my mushroom cakes?
                            1 year ago
                          • No. Perlite is not required for mushroom cakes. However, some people find that perlite helps create a more humid environment for the cakes to grow in, as it helps retain water in the air. You can use perlite if you want, but it is not required.

                              Why did my mushroom cakes stop producing?
                              1 year ago
                            • Mushroom cakes may stop producing due to a number of factors, such as insufficient moisture, an inadequate temperature range, or a lack of necessary nutrients. Too much light, overcrowding, and contamination can also prevent mushrooms from producing. Additionally, if the substrate is depleted of available nutrients, it may no longer be able to support mushrooms. If you are having difficulty determining what is preventing your mushroom cakes from producing, it is best to consult with an expert for assistance.
