The mushroom growing kit you just bought contains mycelium. This mycelium feeds on a substrate made out of spent coffee ground, wood and water. Once ready, the mycelium will reveal primordia, these primordia will eventually become large mushroom fruit bodies called sporocarps that you will probably eat!

With this growing kit you can :

  • Harvest mushrooms directly from the kit while keeping the mycelium indoor or outdoor when the required conditions are met.

  • Exponentially multiply the mycelium network by feeding him (more substrate, more mycelium, more fruiting bodies!)

  • Adopt the companionship strategy with your growing kit. You can encourage associations between your mycelium and other indoor or outdoor plants. Mushrooms and plants are old partners and will often help each other by exchanging nutrients, water and mineral salts.

 

Indoor cultivation

You can harvest directly from the growing kit. Here are some tips to ensure good yields harvests:

  • First, pierce some holes in the two plastic layers of your kit (there is the plastic layer attached to the brown bag and the plastic layer of the other bag that contains the mycelium). Those holes will allow the mycelium to breath and gorge himself with water while allowing for the exceeding water to drip off. For the shiitake kit, you have to remove the mycelium brick completely from both bags.

  • Secondly, soak the growing kit in cold water for 12 to 18 hours. Ideally, you want the mycelium to be completely submerged, you will probably need an object to put on top of it to make sure it doesn’t float. This step is important, it will allow the mycelium to saturate with water and will help him produce big and beautiful fruit bodies.

  • After the 12-18 hours soak, you won’t need the soaking water anymore, you can give it to your plants (except for cacti and other fat plants). Make sure the growing kit is not over saturated and that there is no stagnant water inside the kit. We recommend puncturing small holes under the kit to allow the water to drip off. You can add a plate under the kit to collect the water.

  • Then you only need to find the right spot for your new friend. At this stage, your growing kit is ready to produce his first flush (first harvest). It means that your mycelium is at the fructification stage.

    • There are a few factors to consider in order to help as much as possible your mycelium in this important stage. Those factors are: Humidity, oxygen, brightness and temperature.

Once the mycelium is at the fructification stage (The kits we produce are sold ready-to-grow, the colonization stage has been completed in our production facility) you need to make sure, as much as possible, that your mycelium has access to the following elements:

  • High humidity in the air (50-90%), but no stagnant water.

  • Good oxygen supply

  • Light

  • Temperature around 20 degrees Celsius

  • Humidity: Like us, mushrooms prefer a high relative humidity in the air. The objective here, for the fructification stage, is to maintain a humidity of at least 50% and a maximum of 90% (95% is good too). We recommend putting your growing kit away from heat sources. You can lay it in the pot of a big house plant. Humidity is naturally higher around house plants and the plant will also protect the mycelium from direct sunlight.

You can also create a small humidity tent very easily. To do this, simply deposit the kit on a plate or in a bowl. Then, cover the plate or the bowl with a transparent plastic bag in which you will have pierced several holes (around half an inch wide). And that’s all! This little dome will help create a micro-climate while allowing some air exchange. You can now vaporize the water directly through the holes everyday.

  • Oxygen: Mushrooms «breath» oxygen. When they are into their vegetative state they require less of it, more carbon dioxide helps to the development of the mycelium network. However, once the mushroom is at the fructification stage, it is very important to give him access to oxygen. A lack of oxygen is often visible when the mycelium produces elongated fruiting bodies. To make sure it doesn’t happen, pick a spot in your house where there is some air circulation.

  • Brightness: Mushrooms don’t do photosynthesis like plants. However, light still plays a non-negligible role into the fruit bodies development. Light is a trigger to the primordia formation. Think about the fact that mycelium mostly lives just under the forest’s ground or under the bark of trees. It is mostly protected from direct light when it is in his vegetative state. But once the mycelium reaches the surface, it becomes exposed to light and this is where it produces the fruiting bodies.

Therefore we recommend to allow some light to be in contact with your growing kit. The natural light of a room should suffice. Ideally you don’t want the kit to be in prolonged direct sunlight contact though, as it will rapidly dry it out. Under the big leaf of a houseplant is a fantastic place for your growing kit.

  • Temperature: The normal temperature of your home is adapted to the mushroom cultivation. The species we offer will be comfortable within temperature range of 15-24 degrees Celsius (consult the species sheets to know the optimal conditions for each species). If possible, it is recommended to lower the temperature after the soak of your kit. An abrupt temperature change is another trigger to the primordia formation. 15-17 degrees Celsius for the fructification stage would be optimal but not mandatory.

  • Mycelium: Mycelium is a mushroom in its vegetative state. It is formed by numerous filaments that we call: hyphea. The mycelium is generally just under the surface or inside a dead tree. Most of the time, the mycelium forms the most important mass of the mushroom. It contains the genes of the mushroom, digests food, explores its territory, finds water source, conquers new regions and associates with various plants.

  • Primordium: A primordium (primordia if plural) is the young reproductive organ of a mushroom. It is the equivalent of a plant bud. Once it attains maturity, the primordium becomes a fully working reproductive organ that we call: fruiting body or sporocarp.

  • Fruiting body: The fruiting body or sporocarp is the reproductive organ of the mushroom. It is the fruiting body that will send out millions of spores (billions for particular species) each day. In the common language we call it: mushroom. However, the fruiting body is only one part of the mushroom and it is generally that part that we consume, even though many species possess a highly nutritious mycelium.

  • Spores: A spore is a reproductive cell. Mushrooms, plants, algae and bacteria can produce them. Being small and light, once propelled by the fruiting body of the mushroom, the spores can travel incredible distances with the help of air and water currents. A spore that lands on an appropriate spot will give birth to the first hypha of a new fungi organism. Some spores are extremely resilient and can endure the intense cold of Antarctica or travel though space hidden in debris or asteroids.
