Mushrooms inhale oxygen and exhale carbon dioxide
Mushrooms are a type of fungus that requires food, water, and oxygen to grow. They are not plants, and therefore do not photosynthesise. Instead, they respire like humans, inhaling oxygen and exhaling carbon dioxide (CO2).
CO2 is critical to the growth of mushrooms. It is important to monitor and control CO2 levels during the various stages of mushroom growth to obtain high-quality, large sizes, and overall yield. During the vegetative stage, mushrooms release more CO2 than during the fruiting stage. The ideal CO2 level for mushroom growth is between 10,000–20,000 ppm during the spawning process, but no more than 1,000 ppm during the fruiting phase, preferably between 500 and 800 ppm. If the CO2 concentration is higher than 1,000 ppm during fruiting, yields will decrease.
To monitor CO2 levels, mushroom farmers use CO2 meters, which can be placed in the grow room to detect the amount of CO2 in the air. By managing CO2 levels through ventilation, air exchange, and the use of a CO2 controller or sensor, farmers can achieve consistent CO2 levels and optimise mushroom growth.
While mushrooms contribute to global warming by exhaling CO2, certain types of fungi, such as mycorrhizal fungi, can help forests absorb CO2 and delay the effects of climate change. These fungi form symbiotic relationships with the roots of trees, enhancing their ability to keep carbon locked in the soil and out of the atmosphere.

CO2 levels are critical to mushroom farm success
Mushrooms are unique in that they do not photosynthesize and, therefore, do not rely on carbon dioxide (CO2) for energy production. However, CO2 levels in a mushroom farm significantly affect how mushrooms develop, especially during their fruiting stage.
Mushrooms require varying CO2 concentrations at different stages of their life cycle. During the early Spawn Running (Mycelium Growth) stage, mushrooms can tolerate higher CO2 levels as the mycelium, the root-like network of the fungus, spreads throughout the growing substrate. Once the mushrooms start to pin and enter the fruiting stage, they require lower CO2 levels and higher oxygen (O2) levels. This phase is critical for mushroom formation and expansion. If CO2 levels are too high during fruiting, mushrooms can exhibit abnormal growth, such as elongated stems and underdeveloped caps, reducing their market value.
To ensure successful mushroom farming, it is crucial to maintain optimal CO2 concentrations during each stage of mushroom development. Proper ventilation, use of CO2 sensors, and other CO2 management techniques are essential for preventing deformities and achieving a successful harvest. Regular monitoring of CO2 levels with reliable sensors helps farmers maintain the ideal range for each growth phase. Additionally, controlled ventilation systems can adjust airflow as CO2 levels rise, particularly during pinning and fruiting.
By managing CO2 levels effectively, mushroom farmers can create an ideal environment for their crops, maximizing yield and ensuring high-quality mushrooms for the market. This precision in CO2 control, along with darkness and humidity management, is critical to the success of mushroom farms.

CO2 monitoring is important during pinning, a critical part of mushroom growth
Mushrooms are the fruit of a fungus. They are not plants that take in carbon dioxide (CO2) and produce oxygen. Instead, they respire like humans, taking in oxygen and producing CO2. Therefore, CO2 monitoring is important during pinning, a critical part of mushroom growth.
CO2 levels must be tightly controlled during mushroom growth to obtain high-quality, large sizes, and overall yield. Experts suggest CO2 levels between 10,000 and 20,000 ppm during the spawn run but no more than 1,000 ppm during the fruiting phase, preferably between 500 and 800 ppm. If CO2 concentrations are higher than 1,000 ppm during fruiting, yields will decrease. Mushrooms pin under high CO2 levels and then extend their stems to find oxygen. Excess CO2 as the pins grow results in "legging" or long stems as the developing fruit pushes higher in the air to search for oxygen.
To control CO2 levels in a mushroom grow room, one can increase ventilation by installing fans and vents to maintain a consistent flow of air, preventing stagnant pockets of CO2 from building up. Another effective way to control CO2 levels is to use a CO2 scrubber, which absorbs excess CO2 from the air and releases clean air into the room. One can also use a CO2 controller, a device that monitors and controls the CO2 level in the grow room.
CO2 meters are small but powerful devices that can help monitor and control CO2 levels in mushroom-growing environments, ensuring optimal conditions for crops. They can detect when CO2 levels are too high or too low, allowing growers to make adjustments. This not only leads to healthier and more robust mushrooms but can also increase yields and reduce the risk of contamination.

Mushrooms are the fruit of a fungus
Mushrooms start out as mycelium, a branching, thread-like colony of fungus. The mycelium is grown in compost, which is why mushrooms are often seen growing out of dead tree branches or logs on a forest floor. In order to propagate, the mycelium senses the right combination of temperature and moisture in the air to flower. The result is a mushroom. Mushroom farming attempts to recreate this natural process of mycelium flowering on a commercial scale. When the mycelium is ready, the grower “shocks” the fungus by lowering the temperature of the air and compost, reducing the CO2 level, and increasing evaporation to encourage the growth of pins, some of which transform into fully-formed mushrooms.
Mushrooms are not plants; they do not take in CO2 and produce oxygen. Instead, they respire like humans, taking in oxygen and producing carbon dioxide. CO2 levels are critical to mushroom farm success. Most experts suggest CO2 levels between 10,000 and 20,000 ppm during the spawn run but no more than 1,000 ppm during the fruiting phase, preferably between 500 and 800 ppm. If CO2 concentrations are higher than 1,000 ppm during fruiting, yields will decrease.
While mushrooms themselves produce carbon dioxide, certain types of fungi, called mycorrhizal fungi, can help forests absorb CO2 pollution, delaying the effects of global warming and protecting our planet. These fungi exist entirely underground, growing symbiotically with the roots of trees. While trees in a forest absorb CO2 molecules, they do not do this alone. Scientists have learned that particular root fungi, called ectomycorrhizal fungi, are helping trees absorb CO2 even faster. Additionally, ectomycorrhizal fungi can slow down decomposition, a natural process that returns carbon from forest soils back into the atmosphere.

Some fungi help forests absorb CO2 pollution
Mushrooms are a type of fungus that grows from mycelium, a branching, thread-like fungus colony. Like humans, they require food, water, and oxygen to grow, and they produce carbon dioxide. However, certain types of fungi, such as mycorrhizal fungi, play a crucial role in helping forests absorb carbon dioxide and combat climate change.
Mycorrhizal fungi form intricate underground networks, growing symbiotically with the roots of trees. These fungal networks, also known as the "Wood Wide Web," enhance the ability of forests to absorb and store carbon, preventing it from entering the atmosphere and contributing to global warming. Through their partnership with trees, these fungi help to keep carbon locked up in trees and soils, delaying the effects of climate change.
Research by Boston University scientists Colin Averill and Jennifer M. Bhatnagar highlights the importance of these fungi in the forest microbiome. Their work demonstrates how mycorrhizal fungi contribute to carbon sequestration and protect against soil loss and plant diseases. The presence of these fungi in forest ecosystems is vital, as they receive and store carbon from plants, acting as a significant carbon sink.
However, mycorrhizal fungi, particularly the ectomycorrhizal variant, are under threat from nitrogen pollution caused by burning fossil fuels and agricultural practices. This pollution is leading to the loss of these crucial "fungal carbon guardians," resulting in increased CO2 emissions and accelerated climate change. Therefore, conservation efforts and sustainable land management practices are essential to protect these vital fungal networks and mitigate their loss.
In summary, while mushrooms and other fungi produce carbon dioxide, specific types of fungi, such as mycorrhizal fungi, play a significant role in helping forests absorb CO2 pollution and combat climate change. These fungi form underground networks that enhance carbon absorption and storage, making them valuable allies in the fight against global warming. Protecting and understanding these fungal ecosystems is crucial for preserving their climate-mitigating capabilities.
