A mushroom room, or grow room, is an enclosed space that mimics the conditions and environment in which mushrooms grow
The size of a mushroom room can vary depending on the scale of the operation and the desired number of mushrooms. For small-scale growers, a mushroom grow room can be as compact as a closet or a small tent, while commercial growers may convert entire rooms, shipping containers, or even buildings into mushroom fruiting chambers. The design and characteristics of the mushroom room will depend on the specific requirements of the mushroom species being cultivated.
When setting up a mushroom room, it is essential to select an appropriate space that meets the necessary conditions for mushroom growth. A cool, dark, and well-ventilated area is ideal. Basements, spare rooms, and large closets can be transformed into effective mushroom grow rooms. Cleanliness is also crucial to prevent contamination and ensure the success of the crop. The space should be thoroughly cleaned and sterilised before use.
Maintaining the right temperature, humidity, lighting, and airflow levels is vital for successful mushroom growth. Most mushroom species thrive in a temperature range of 60-75°F (15-24°C). Investing in a thermometer, humidifier, and fans can help monitor and regulate the environmental conditions within the mushroom room. Additionally, it is important to prevent the buildup of carbon dioxide and ensure proper air circulation.
Pests, such as mites, flies, and slugs, can pose a threat to the mushroom crop. Regular inspections for signs of pests are necessary, and immediate action should be taken if any are detected. Sealing any openings or gaps in the mushroom room can help prevent pests from entering and causing damage to the crop. Overall, creating a mushroom room involves carefully controlling and maintaining various environmental factors to optimise the conditions for mushroom growth.

The size of a mushroom room depends on the scale of the operation and the amount of mushrooms to be grown
A mushroom fruiting chamber or a mushroom grow room is an enclosed space that growers use to mimic the conditions and environment that different species of mushrooms would normally grow in, helping the mushrooms grow successfully. The size of a mushroom room depends on the scale of the operation and the amount of mushrooms to be grown.
For smaller home growers, a fruiting chamber may be as simple as a plastic tote, a closet, or a mini greenhouse. For large commercial growers, entire rooms or shipping containers can be converted into fruiting chambers to produce very large amounts of mushrooms per week. A small mushroom greenhouse, also known as a Martha tent, can be a good option for those with limited space. These tents are cheap and come with a waterproof outer shell and a racking system to hold mushroom blocks. One grow block can typically fit in 1 sqft of space.
If you're looking to produce a larger amount of mushrooms, a bigger space such as a garage, basement, or warehouse may be more suitable. The size of the room will depend on the desired number of mushrooms and the space available. For serious commercial operations, a room size of 25 feet by 15 feet (about 8 meters by 5 meters) can produce around 150 to 200 pounds (about 68 to 91 kilograms) of mushrooms per week.
It's important to consider the layout of the room, including shelving, racks, or containers, and to leave enough space to navigate, harvest mushrooms, and carry them out. The room should also be easy to clean and have proper air circulation to prevent the buildup of carbon dioxide. Additionally, the temperature, humidity, and lighting should be regularly monitored and adjusted as necessary to create the optimal environment for mushroom growth.

Different mushrooms have different requirements, so the design and characteristics of a mushroom room will vary
A mushroom fruiting chamber, or a mushroom grow room, is an enclosed space that growers use to mimic the conditions and environment in which different species of mushrooms would normally grow, helping the mushrooms grow successfully. Different mushrooms have different requirements, so the design and characteristics of a mushroom room will vary.
For instance, Oyster mushrooms like a lot of fresh air and will grow smaller caps in a high CO2 environment. Lion’s Mane, on the other hand, is not as picky about CO2 but is fussy about big swings in temperature and humidity. This knowledge is gained through careful attention to your grow room and experimenting with different parameters to optimise the environment for your mushrooms.
The size of your mushroom grow room will depend on the scale of your growing operation and the amount of mushrooms you want to grow each week. For smaller home growers, a fruiting chamber may be as simple as a plastic tote or a mini greenhouse (also known as a Martha tent). For larger commercial growers, entire rooms or shipping containers can be converted into fruiting chambers to produce very large amounts of mushrooms per week.
The space you use for your mushroom grow room should be cool, dark, and well-ventilated. A basement, spare room, or large closet can be transformed into an ideal environment for mushroom cultivation. Cleanliness is essential to prevent contamination and ensure the success of your mushroom crop. Seal any openings or gaps to prevent pests from entering the grow room.
Maintaining the right temperature and humidity levels is vital for the growth of mushrooms. Most mushroom species thrive in a temperature range of 60-75°F (15-24°C). You can invest in a thermometer and a humidifier to monitor and regulate the conditions in your grow room.

Maintaining the right temperature, humidity, CO2 levels, and lighting is vital for mushroom growth
A mushroom room is a small greenhouse or grow tent where mushrooms are cultivated. Maintaining the right temperature, humidity, CO2 levels, and lighting is vital for mushroom growth.
Temperature plays a crucial role in mushroom growth. While most mushrooms fruit well at temperatures between 10°C and 28°C, temperatures below zero or above 35°C will likely harm them. Mushrooms can grow year-round in most parts of New Zealand without the need for heating or cooling. However, the warmer it is, the faster they grow. Mushrooms grown in the summer can suffer from heat stress and have ruffled or thin edges. On the other hand, mushrooms grown in the winter develop a more complex flavour and a wonderful texture.
Humidity is another critical factor in mushroom cultivation. Mushrooms require high humidity levels to initiate the formation of primordia, which eventually develop into mature mushrooms. Throughout their life cycle, mushrooms need humidity to ensure they reach maturity. The ideal humidity level for mushroom growth is between 80% and 90%. If the humidity level falls below this range, mushrooms may dry out and stall their growth. However, excessively high humidity can promote the growth of mould and other harmful microorganisms.
CO2 levels are essential for mushroom growth and yield. While mushrooms require CO2 for respiration, excessive CO2 can cause them to grow too quickly, resulting in poor quality and low yield. Conversely, insufficient CO2 can slow down growth and produce small or deformed mushrooms. The ideal CO2 level during the spawning process is between 10,000 and 20,000 ppm, while no more than 1,000 ppm is needed during the fruiting phase.
Lighting is also important for mushroom growth, particularly during the fruiting process. While some growers prefer using specific LED lights or fluorescent (CFL) lighting, others rely solely on natural daylight. Light intensity and heat are primary considerations when selecting lighting for mushrooms.

Cleanliness is essential to prevent contamination and ensure the success of the mushroom crop
Maintaining impeccable cleanliness is of paramount importance in a mushroom growing room. The success of your mushroom crop heavily relies on preventing contamination by ensuring a sterile environment. Here are several key practices to achieve this:
Sanitize All Equipment: Before introducing any equipment into the mushroom room, it must be thoroughly sanitized. This includes shelves, trays, tools, and any containers used for spawning or substrate preparation. Wash all reusable equipment with hot, soiled water and then rinse it with clean, lukewarm water. Subsequently, disinfect the equipment using a food-safe sanitizer or a mild bleach solution, being careful to rinse again with sterile water afterward. Make sure to also disinfect any tools or machinery used for harvesting or maintenance tasks before each use.
Keep the Room Sealed and Controlled: The mushroom growing room should be a controlled environment with limited access. Keep doors and windows closed to prevent wild spores and pests from entering. Use air filters and maintain a slight positive pressure in the room to ensure that outside air is always being pushed out rather than pulled in, which can help prevent the entry of contaminants. Regularly service and replace air filters as needed to ensure optimal performance.
Practice Good Hygiene: Anyone entering the mushroom room should follow strict hygiene protocols. This includes wearing clean, dedicated footwear and sterile gloves, as well as donning a hairnet or cap and a face mask. Ensure that all clothing and protective gear are free of debris and contaminants. Provide handwashing stations and, if necessary, shower facilities for staff, and enforce their use before and after entering the growing area.
Maintain a Clean Room: The growing room itself must be kept immaculately clean. Regularly disinfect all surfaces, including walls, floors, and ceilings, using appropriate fungicides and sanitizers. Remove any debris, dead mushrooms, or contaminated substrate immediately. Avoid using brooms that can stir up spores and instead, opt for vacuums with HEPA filters to ensure that any debris is captured effectively. Keep the room well-organized to facilitate easy cleaning and to identify potential problem areas quickly.
Prevent Contamination at the Source: In addition to sanitizing equipment, it is crucial to ensure that your starting materials are also contaminant-free. Purchase spawn and substrate from reputable suppliers with good hygiene practices. If you are preparing your own substrate, ensure that the ingredients are sterile and free of pests or diseases. Properly pasteurize or sterilize substrate to eliminate any potential contaminants.
By implementing these practices, you can significantly reduce the chances of contamination and create an optimal environment for your mushroom crop to thrive. Cleanliness is the cornerstone of successful mushroom cultivation, ensuring that your efforts yield abundant and healthy mushrooms.
