The easiest mushrooms to start growing are Oyster mushrooms.

They can be grown on toilet paper, books, and newspapers; some have seen them grow on concrete! These ever increasing mediums are called substrates.

Oyster mushrooms grow quickly and aggressively and are ready in about 1-2 weeks.

What mushrooms can I grow at home?

You can grow gourmet mushrooms like shitake, oyster, reishi, and lion's main.

Wild mushrooms like morels and chanterelles cannot be grown at home as we cannot replicate the delicate process that occurs in the wild.

How do I get started?

You could purchase a mushroom grow kit or start growing from a substrate.

How do I grow organic mushrooms from a substrate?

This is the fun part. I grow mushrooms from a hay substrate. Here's how:

List of materials:

Mushroom Spawn/Seed (can be found on eBay)

  • Purchase hay relatively cheaply, as it's used for pet rabbits. Click here to see the one I purchased on Amazon for £4.29

  • Purchase mushroom grow bags here on Amazon for £5.09

  • Boil or pressure cook the hay to kill all the germs

  • Fill the bag with the hay

  • Then add your mushroom spawn and leave for 20 to 30 days until the substrate turns white

  • When the substrate turns white, start spraying with water twice a day

  • Then, harvest your mushrooms by twisting and pulling them off the substrate.

See the video below for an example of how this is done:

How do I grow mushrooms at home from a kit?

The easiest way to grow mushrooms is to purchase a premade growing kit.

Once your kit arrives, you cut an X into the middle and spray it with water twice daily. Your mushrooms will be ready in 1-2 weeks.
