Growing your own mushrooms at home is a rewarding and surprisingly simple process. Whether you love the taste of fresh mushrooms in your cooking or want to explore the fascinating world of fungi cultivation, starting your own small-scale mushroom farm can be a fun and productive hobby. Unlike traditional gardening, mushroom cultivation does not require large outdoor spaces or direct sunlight, making it an ideal indoor activity.
This guide will walk you through everything you need to know to start growing your own mushrooms at home, from selecting the right type of mushrooms to harvesting your first crop.
Choosing the Right Mushrooms to Grow
Before you get started, it’s important to decide which type of mushrooms you want to grow. Some mushrooms are easier to cultivate than others, making them ideal for beginners. Here are a few popular options:
Oyster Mushrooms – One of the easiest and fastest-growing mushrooms. They thrive in various conditions and require minimal care.
White Button Mushrooms – Commonly found in supermarkets, these mushrooms are beginner-friendly but require a bit more patience.
Shiitake Mushrooms – Known for their rich flavour, these mushrooms grow well on hardwood logs or sawdust blocks.
For first-time growers, oyster mushrooms are an excellent choice due to their adaptability and rapid growth.
Setting Up Your Mushroom Growing Environment
Unlike traditional plants, mushrooms don’t need sunlight to grow. Instead, they require a humid, dark, and controlled environment. Here’s what you need to set up your growing area:
1. Choose a Suitable Growing Medium
Mushrooms grow on various substrates, including straw, sawdust, coffee grounds, or pre-made mushroom grow kits. Each mushroom species has a preferred growing medium. For instance:
- Oyster mushrooms grow well on straw or coffee grounds.
- Shiitake mushrooms thrive on hardwood logs or sawdust.
- Button mushrooms prefer composted manure.
2. Find the Right Growing Container
You can grow mushrooms in plastic bags, buckets, or even dedicated mushroom-growing trays. Ensure the container has some ventilation holes to allow air exchange while maintaining humidity.
3. Control Temperature and Humidity
Mushrooms require specific temperature and humidity levels for optimal growth:
- Most mushrooms thrive between 15-24°C.
- Humidity levels should be around 80-90%.
- Indirect light or complete darkness is best for most species.
To maintain humidity, you can use a spray bottle to mist your growing area or place a humidifier nearby.
The Mushroom Growing Process
Once your growing environment is ready, follow these steps to start the cultivation process:
1. Inoculate the Growing Medium
Inoculation is the process of introducing mushroom spores or mycelium (the vegetative part of fungi) into the growing medium. If using a pre-made mushroom growing kit, this step is often already completed for you.
- If using spores, mix them into the substrate and pack the material into your chosen container.
- If using spawn (pre-grown mycelium), evenly distribute it throughout the growing medium.
2. Incubation Period
During this phase, the mycelium spreads through the substrate. Keep your container in a dark, warm space with proper humidity. This process can take anywhere from 1 to 4 weeks, depending on the mushroom species.
3. Fruiting Stage
- Once the mycelium has colonised the substrate, it’s time for mushrooms to start forming.
- Move the container to an area with slightly more indirect light and fresh air circulation.
- Maintain proper humidity by misting the substrate regularly.
- Tiny mushroom pins will begin to appear and develop into mature mushrooms within 5 to 10 days.
Harvesting Your Mushrooms
Mushrooms are ready to harvest when their caps fully open but before they start releasing spores. Use a sharp knife or scissors to cut them at the base. Avoid pulling them out, as this can disturb the remaining mycelium and affect future growth.
Troubleshooting Common Mushroom Growing Problems
Even with proper care, you might encounter some challenges. Here are a few common issues and their solutions:
Mould or Contamination – If you notice unusual colours or strong odours, your substrate may be contaminated. Always use sterilised materials and clean hands/tools when handling mushrooms.
Slow Growth – If your mushrooms aren’t growing as expected, check the temperature and humidity levels.
Drying Out – If your substrate dries out, mist it more frequently to maintain moisture.

Storing and Using Your Homegrown Mushrooms
Once harvested, fresh mushrooms can be stored in the refrigerator for up to a week. To extend their shelf life, you can also:
- Dry them using a dehydrator or by air-drying.
- Freeze them after blanching to preserve texture and flavour.
- Pickle or preserve them in oil for long-term storage.
Conclusion
Growing mushrooms at home is an exciting and sustainable way to enjoy fresh, organic produce. With the right setup and a little patience, you can harvest delicious mushrooms in just a few weeks. Whether you choose to grow oyster, shiitake, or button mushrooms, the process is simple and highly rewarding. If you’re looking for high-quality mushroom spores and growing kits, the Aussie Mushroom Store is a great place to start your journey. Happy growing!
