Firstly, in order to grow psilocybin mushrooms at home, you’ll need the following equipment. 

If you’r buying a grow kit online, many of the items below may be included. Alternatively, most of the items on the list can be purchased from Amazon.  


Inoculation jars can either be purchased online or you can use cheap mason jars from Wilkos

For Phase 1 of the process you will need…

For Phase 2 of the process, you will need… 

The Process 

We’ve divided the process into 2 phases.  

Phase 1 is when you’ll create what’s known as a birthday cake. This is when mycelium has fully colonised your jar around the substrate and is ready for phase 2.  

Phase 2 is the process of removing the birthday cake from the jar and moving them to a container where they’ll sprout mushrooms.  

This may all sound complicated at first, however, after several read-throughs it will become clear. 

Phase 1 

  1. Sterilise  

Sterilisation is arguably the most important stage of growing mushrooms. Firstly, you need to select a closed off space in your house (e.g. your bathroom).

Then, gather all items needed for phase 1 and put on your face mask. Enter the room and close the door. Spray the room with your disinfectant spray.

Finally, put on your gloves and wipe your jars with the rubbing alcohol using paper towels, making sure to take extra care with the top of the jar.  

  1. Inoculate  

Using a lighter, heat the metal portion of your hypodermic needle until it glows red – this will sterilise it. Then, shake your syringe to distribute the spores evenly.

Insert the needle into the port and inject one cc into the jar. Repeat the process with each jar, ensuring you sterilize your hypodermic needle each time.  

  1. Leave for at least 15 days 

Place your jars in a cardboard box, close the lid, and then place in a dark, warm place. It needs a temperature of roughly 80-85 degrees Fahrenheit.

During the first week, try not to check on your mushrooms as they need the dark to grow. After a week you should see a white fuzzy substance in the jars. This is mycelium, the vegetative part of the fungus much like the roots of a plant.

Let the mycelium grow until the jars are 100% colonised by white fluffy mycelium. After you’ve reached this point wait another week and proceed to Phase 2. 

Phase 2 

In this phase we remove the birthday cakes from their jars so that they can start sprouting mushrooms.  

  1. Birth and soak the birthday cakes  

By now your jars should be fully colonised by mycelium and ready to be placed in a fruiting chamber (a clear plastic tub). However, as they have been in an airtight container, they’ll be in need of some water. Soak them for 12-24 hours using the following method.  

Now your cakes are hydrated the next step is to prepare your chamber.  

  1. Prepare the chamber 

Firstly, you’ll need to sterilise the plastic container with bleach and boiled water and be sure to rinse thoroughly.  

Fill your spray bottle with 10 parts boiled water to one part hydrogen peroxide.  

Sterilize your vermiculite by soaking another solution of 10 to 1 boiling water and hydrogen peroxide. Then, spread a layer on the bottom of your growing chamber. The goal of the vermiculite is to maintain humidity with the assistance of daily sprays.  

Next, place your mason jar lids into the bed of vermiculite, then place a cake on each lid. Spray each cake with your h2O/h2O2 mixture but not too much – make sure a puddle doesn’t form. Leave enough room between each cake, so there’s plenty of room for mushrooms to sprout without crowding.  

You may see small mushroom sprouts on your cakes known as pins, this is a good thing as it’s the first stage of sprouting. If you smell any foul odours coming from your mushrooms, it’s possible that your mycelium may have harmful bacteria.  

  1. Step Three 

Seal the lid on your growing chamber and leave it in a well-ventilated room with indirect sunlight.  

With everything now set up you can leave your mushrooms to sprout.
