How To Grow Mushrooms Indoors Step By Step?

To grow mushrooms indoors, choose the right mushroom species, prepare the substrate material, incoulate, incubate the inoculated substrate, create a fruiting chamber, monitor the growth, and maintain the process. Cultivating mushrooms indoors is a rewarding hobby that can provide a steady supply of fresh, organic mushrooms throughout the year.

– Choose Your Mushroom Species

Different types or varieties of mushrooms can be grown indoors, such as shiitake, oyster, button, and portobello mushrooms. Select a species that will grow well in your area.

– Prepare Your Substrate

The substrate is the material that the mushrooms will grow on. It can be a variety of materials, such as straw, sawdust, or compost, as these would keep the right amount of moisture trapped. Sterilize or pasteurize the substrate to kill any unwanted microorganisms that may compete with the mushrooms.

– Inoculate Your Substrate

Once the substrate has cooled, inoculate it with mushroom spawn, keeping in mind that this material contains mushroom spores and will colonize the substrate. Allow your mushroom substrate to incubate in a warm, dark place until the mycelium has fully colonized the substrate. Make sure the substrate stays moist by misting it with water regularly.

– Create A Fruiting Chamber

Transfer the mycelium to a fruiting chamber when it has colonized the substrate. This can be a simple plastic tub or a commercially available growing kit. Keep the environment humid and well-ventilated.Creating Fruiting Chamber for Mushroom

For this choice, you must remember that if proper airflow is provided, it helps to ensure that the carbon dioxide produced by the growing mushrooms is replaced by fresh air, reducing the risk of suffocation or buildup of harmful gasses. It may also help the process to prevent the growth of harmful bacteria or mold on the mushrooms by maintaining a clean and sanitized growing environment.

– Provide the Right Requirements

The ideal indoor conditions for safely growing mushrooms include providing a warm and humid environment with good air circulation, which would trigger their growth. For this reason, know that the temperature should be kept somewhere between 60 and 80 degrees Fahrenheit, and in parallel to this, the humidity level must be between 60 and 80 percent.

Moreover, it’s important to know how humidity levels that are excessively high or too low can also lead to a risk to the safety of mushroom cultivation. On the contrary, high humidity can cause the growth of harmful bacteria or mold, while low humidity can cause the mushrooms to dry out and become less productive.

– Monitor And Maintain

Maintaining a clean and sanitized growing environment is critical to prevent contamination and the growth of harmful bacteria or mold on the mushrooms. Proper ventilation is necessary to resist the buildup of carbon dioxide and other harmful gasses. Monitoring the temperature, humidity, and growing conditions is necessary to ensure the mushrooms grow safely and healthily.

Monitor the fruiting chamber’s humidity, temperature, and carbon dioxide levels. Mist the substrate regularly to maintain moisture levels. Harvest the mushrooms when they are mature and ready to eat.

– Mushroom Growing kits

There are various methods and kits available to help simplify the process. For instance, if you wish to choose the Back to the Roots Organic Mushroom Grow as a kit that you can use when you wish to grow different mushrooms.

Airflow and humidity levels largely impact mushroom cultivation safety, as insufficient airflow can lead to the buildup of carbon dioxide and other harmful gasses, which can be dangerous for the mushrooms and humans in the area. This is why you should know how poor ventilation can also increase the risk of contamination from mold or harmful bacteria.

Choosing a suitable growing medium and ensuring proper moisture and temperature levels are also key factors. Place the container somewhere with indirect light and keep temperatures between 50 and 75 degrees Fahrenheit, so remember to spritz it twice daily with water.


It is important to create the ideal growing conditions, including proper temperature, humidity, and air circulation, and to use a sterile planting mix to prevent contamination. Here’s a summary of what we covered:

  • Indoor mushroom growing requires a clean, well-ventilated area with proper temperature and humidity control and safe cultivation practices.
