How to Grow Mushrooms from Spores

In growing plants, you will need soil and seeds. In growing mushrooms, you will need compost and the spores.

The spores should be mixed with materials they could feed on like grain, sawdust, straw, and wood chips. When you mix the store with the said materials, you make what is called a spawn. 

The environment

Mushrooms prefer the dark. When it comes to the atmosphere, mushrooms prefer a cool yet humid environment. 

So, at home, you could grow mushrooms in the basement. Under the sink works, too. If people frequent the basement, make sure that the mushrooms are in a closet where they are not exposed to light. 

Good rule of thumb:

Between 55℉ and 60℉ should be a good temperature. 

Now, the following steps are generic steps to grow mushrooms. You can also grow mushrooms based on the instruction for specific types. 

But generally, the following steps will do:

1. Create your spawn

This is going to be quite complex. The easiest way is to just buy the spawn or a mushroom kit. If not, here are the steps:

  • Cut up cardboard into small pieces. 
  • Pour boiling water on the pieces of cardboard.
  • Drain and dry the cardboard bits.
  • Get a container with a lid and poke some holes on it. 
  • Put your cardboard in the container and make it compact. 
  • Cut the stalk / stem butts of the fresh mushrooms and put them on top of your cardboard pieces.
  • Cover with another layer of the moist cardboard pieces. 
  • Wait for colonization.


You will have spawn in less than two weeks. You will know when you have the spawn because the entire cardboard has been colonized by the spawn–the color will change.

2. Prepare your materials 

  • Tray or box with depth of at least seven inches
  • Spawn
  • Mushroom compost
  • Heating pad
  • A little soil

3. Fill box

Put six-inch compost in the box. Then, you can sprinkle the spawn on top. 

4. Heat the box

Put a heating pad under the box so that the compost will have a temperature of around 70℉. You can do this for around three weeks or until you see something growing. 

What you will see is called mycelium. It’s a white thread-like structure. 

5. Cover with soil

Top the material with an inch of potting soil. Buy a potting soil from the store because this has nutrients in them. You don’t want the mushrooms to be contaminated. 

You may now adjust the heat to around 55℉ and 60℉.
