DIY Mushroom Fruiting Chamber

Have you ever wanted to grow your own mushrooms but felt discouraged when you couldn’t find the right environment or equipment? Fear not! By creating your own DIY mushroom fruiting chamber, you can easily grow your own mushrooms at home. In this article, we will guide you through the process of building your own chamber and provide tips on how to maintain optimal conditions for growing mushrooms.

Building Your Fruiting Chamber

To start, you will need to gather the following materials:

– A plastic storage bin with a lid
– A drill
– A hygrometer
– A humidifier
– Perlite or vermiculite
– A thermometer
– Growing containers (e.g. jars, bags, or containers)

Step 1: Drill holes in the storage bin lid. For optimal air circulation, drill several small holes across the lid. Make sure the holes are not too big as that can cause too much airflow and disrupt the humidity levels.

Step 2: Place the hygrometer and thermometer in the bin. The hygrometer will help you monitor the humidity levels and the thermometer will help you monitor the temperature.

Step 3: Place a layer of perlite or vermiculite at the bottom of the bin. This will help to maintain humidity levels by absorbing and releasing moisture into the air.

Step 4: Place your growing containers on top of the perlite or vermiculite layer. You can also add a heat source such as a heat lamp or heating pad to maintain a constant temperature.

Step 5: Connect a humidifier to the fruiting chamber to regulate humidity levels and add moisture as necessary.

Maintaining Your Fruiting Chamber

Now that you have built your fruiting chamber, it is important to maintain optimal conditions for growing mushrooms. Here are some tips on how to do so:

– Monitor humidity levels regularly and add moisture as necessary with the help of the humidifier.
– Keep the temperature within the optimal range for the type of mushroom you are growing. Different types of mushrooms have different temperature requirements.
– Ensure proper air circulation by opening the lid of the chamber periodically.
– Use a sealant to ensure that your fruiting chamber is well-sealed and that outside air does not affect the humidity and temperature levels.


Q1. Can I use any type of plastic storage bin to build my fruiting chamber?
A1. It is best to use a clear plastic bin as this will allow for optimal light exposure.

Q2. What should the temperature and humidity levels be for growing mushrooms?
A2. The optimal temperature and humidity levels will vary depending on the type of mushroom you are growing. Research the specific requirements for your chosen mushroom species.

Q3. Should I add a light source to the fruiting chamber?
A3. Depending on the mushroom species, you may need to add a light source. For example, some mushrooms require light exposure to fruit.

Q4. Can I use soil instead of perlite or vermiculite?
A4. It is not recommended to use soil as it can introduce unwanted bacteria and fungi into your grow environment.

Q5. How often should I check on my growing containers?
A5. Check on your containers daily to ensure that they are not drying out or developing unwanted contaminants.
