Oyster mushrooms home grown in substrate

How to Grow Oyster Mushrooms at Home

Congratulations on your decision to grow oyster mushrooms at home! We wish you the best of luck as you embark on this exciting journey of mushroom cultivation. Oyster mushrooms are considered relatively easy to grow, especially for beginners who are just starting with mushroom cultivation. Oyster mushrooms are fast-growing, adaptable to a wide range of growing conditions, and they don’t require a complex substrate like some other mushroom species. 

They can be grown on a variety of materials such as hardwood sawdust, soy hulls, wheat straw, sugarcane, coffee grounds, banana leaves, cardboard, and coco-coir. Oyster Mushrooms also have a relatively short incubation period of under two weeks.

However, with any mushroom grow, there are a few essential steps to follow to grow oyster mushrooms at home.

For oyster mushrooms to form proper fruits, they need the right combination of light, humidity, fresh air throughout most of the growing process, and following a suitable substrate recipe. By following these steps, even a beginner cultivator can have a successful oyster mushroom harvest.

Tips on How to Grow Oyster Mushrooms at home:

Get your supplies:

You’ll need mushroom spawn, a substrate, a container, a spray bottle, and a humidifier.

Mushroom spawn is the mycelium, or vegetative part of the mushroom, that will colonize your substrate. You can buy mushroom spawn online or from a local supplier. A common substrate for oyster mushrooms is straw or sawdust, which you can buy or make yourself. The container can be a plastic bin or a bag.

Prepare your substrate:

  • If you’re using straw, chop it into small pieces and soak it in water for several hours.
  • Drain the water and put the straw into a pot, adding enough water to cover it.
  • Bring to a boil and simmer for an hour.
  • Drain the water and let the straw cool.
  • If you’re using sawdust, sterilize it by boiling or pressure cooking.

Add spawn to the substrate:

Once the substrate has cooled to room temperature, mix in the mushroom spawn. The spawn should be evenly distributed throughout the substrate.


Place the substrate in a container and cover it with a lid or plastic wrap with small holes poked in it to allow air exchange. Keep the container in a warm, dark place for about two weeks to allow the mycelium to colonize the substrate. During this time, mist the substrate with water using a spray bottle to keep it moist.


Once the mycelium has colonized the substrate, it’s time to induce fruiting. Move the container to a cooler place with indirect light and high humidity. You can use a humidifier or mist the substrate regularly to maintain high humidity. Oyster mushrooms don’t require a lot of light, but they do need fresh air, so make sure to provide ventilation.


Oyster mushrooms will grow in clusters and will mature within a week or two. You can harvest them by twisting them off the substrate or cutting them with a sharp knife. Once you’ve harvested all the mushrooms, you can start the process again with fresh substrate and spawn.

That’s it!

We wish you the best of luck as you embark on this exciting journey. With a little patience, attention to detail, and a lot of love, you’ll be rewarded with a bountiful harvest of delicious and nutritious oyster mushrooms. 

Remember to keep your substrate clean and sterile, maintain optimal growing conditions, and enjoy the process of watching your mycelium grow and transform into beautiful mushrooms.

May your efforts to grow oyster mushrooms  be fruitful and your harvest be abundant.
