Controlling temperature levels when growing mushrooms is essential for a successful harvest. By using a thermometer/temperature sensor, heating pad, cooling fan, or greenhouse, you can achieve the ideal growing conditions for your mushrooms. It is important to monitor the temperature levels regularly and make any necessary adjustments to ensure healthy and thriving mushrooms.

Mushroom growing is a fascinating hobby and can even be a profitable business venture. However, it requires a bit of know-how to ensure successful growth. One of the most important factors that determine the growth and yield of mushrooms is temperature control. The ideal temperature range for mushroom growth is narrow, and it’s crucial to maintain the right temperature to avoid stunted growth or contamination.

By creating the perfect environment with the right temperature, humidity, and ventilation, you can ensure optimal mushroom growth. In this guide, we will explore some of the best methods for controlling the temperature in your mushroom growing setup, including heating and cooling options, as well as how to monitor and adjust temperature levels. Whether you’re just starting out in the hobby or looking to improve your mushroom-growing skills, this guide will provide you with the knowledge and tools you need for success.

Why Control Temperature Levels When Growing Mushrooms?

Mushrooms are one of the most delicate and temperamental crops to grow. They require specific conditions to thrive, and temperature is one of the most crucial factors for mushroom growth. The ideal temperature range for mushroom growth varies depending on the species, but most mushrooms prefer a temperature range between 65-75 °F. Maintaining a consistent temperature is crucial, as even small fluctuations can impact the growth rate and quality of the mushrooms.

Temperature control is essential during all stages of mushroom growth. During the incubation stage, which typically lasts two to three weeks, the temperature needs to be maintained between 65-75 °F. This stage is crucial for the formation of the mycelium, which is the vegetative part of the mushroom. Once the mycelium has formed, it’s time to move on to the fruiting stage. During this stage, the temperature needs to be lowered to around 60-65 °F to encourage the growth of the fruiting bodies.

In addition to controlling the temperature, it’s also essential to monitor and control the humidity levels. Mushrooms require a high level of humidity, typically around 85-95% relative humidity, to grow properly. If the humidity levels are too low, it can cause the mushrooms to dry out and become stunted. Conversely, if the humidity levels are too high, it can lead to mold growth and other issues.

Ways To Control Temperature Levels When Growing Mushrooms

One of the easiest ways to control temperature levels when growing mushrooms is a thermometer or temperature sensor. A thermometer or temperature sensor is an easy way to monitor the temperature of the growing medium and the surrounding environment. This will help you to adjust the temperature as needed to achieve the ideal growing conditions for your mushrooms.

Another effective and extremely popular way to control the temperature when growing mushrooms is by using a heating pad or mat. This can easily be placed underneath the growing container to provide a steady source of heat. Heating pads and mats are available in different sizes to cover your entire growing area, and they can also be adjusted to the desired temperature. Heating pads/mats are so popular as they are also easy to use and can be placed anywhere in the growing area.

Additionally, you can use a cooling fan to control the temperature levels when growing your mushrooms. This is especially useful if the growing area becomes too warm. A cooling fan can be used to increase air circulation and quickly lower the temperature in the growing area. This will prevent the mushrooms from overheating and becoming damaged.

Finally, you can also use a greenhouse or grow tent. These handy structures provide an enclosed environment that can be easily controlled using a heating or cooling system. They also allow for better humidity control, which is essential for mushroom growth. Many heating and cooling systems can now also be set up on your smartphone, which means you can keep an eye on your mushroom’s health 24/7!

What Happens When The Temperature Is Too Low When Growing Mushrooms?

When the temperature is too low, the mycelium, which is the vegetative part of the mushroom, will slow down or even stop growing altogether. This can lead to stunted growth and a lower yield of mushrooms overall.

Also, if the temperature drops below a certain threshold, the mycelium can even die off completely. This is because mycelium is part of the living body of the mushroom, which requires a certain level of warmth to survive and thrive. If the temperature drops too low, the mycelium will simply shut down and stop growing, resulting in a failed crop.

It is important to note that different types of mushrooms have different temperature requirements, so it is important to research the specific variety of mushrooms you are growing and ensure that you are providing the optimal temperature for its growth.

If you are new to the hobby, here are some common indoor mushrooms and their optimal temperatures. 

  • Oyster Mushrooms: 70–85 °F.
  • Reishi Mushrooms: 70–80 °F
  • Antler Reishi Mushrooms: 60–80 °F
  • Shiitake Mushrooms: 50–80 °F
  • King Stropharia Mushrooms: 60–80 °F

How To Increase The Temperature When Growing Mushrooms?

If you’re wondering how to increase the temperature when growing mushrooms, there are several methods you can try.

One of the most effective ways to increase the temperature in your mushroom growing area is by using a heating system. This can be achieved through the use of a space heater, heating mats, or even an infrared bulb. The type of heating system you choose will depend on the size of your growing area and the type of mushrooms you’re cultivating. 

It’s important to note that some varieties of mushrooms are more sensitive to temperature changes than others, so check the ideal temperature range for your specific mushroom variety before using a heating system.

Another way to increase the temperature in your mushroom growing area is by insulating the space. This involves covering the walls, ceiling, and floor with a layer of insulation material. This will help to trap heat inside the growing area and prevent it from escaping. Common insulation materials include foam boards, fiberglass, and reflective insulation like aluminum foil.

In addition to these methods, you can also try placing the growing containers in a warm room or near a heat source such as a furnace or radiator. However, it’s important to ensure that the temperature doesn’t become too high, as this can have adverse effects on the mushrooms.

What Happens When The Temperature Is Too High When Growing Mushrooms?

When the temperature is too high, the mycelium or the vegetative part of the mushroom can be damaged. This can lead to impeded growth or cause the mushroom to die. High temperatures can also cause intense dehydration in the mushroom’s body, which can affect the texture and flavor of the final product. The heat can also encourage the growth of harmful bacteria and fungi, which can spoil the mushrooms.

In addition, high temperatures can also affect the quality of the substrate or the growing medium. The heat can cause the substrate to dry out quickly, which can lead to poor mushroom yield. It can also encourage the growth of unwanted microorganisms, which can compete with mycelium for nutrients.

How To Lower The Temperature When Growing Mushrooms?

The first step is to identify the source of heat that is causing the temperature to rise. It could be a heating system, lighting, or even the heat generated by the mushrooms themselves. Once you have identified the source, you can take steps to reduce it. For instance, you can turn off the heating system or reduce the light intensity.

Another way to lower the temperature is to increase the ventilation in the growing area. This can be achieved by installing fans or opening windows in your growing area to circulate the air. This will help to dissipate the heat and keep the temperature at a comfortable level for the mushrooms.

Additionally, you can use a cooling system such as an air conditioner or a water-cooling system to lower the temperature. These systems work by removing the heat from the air and circulating cooler air back into the growing area. However, they can be expensive to install and operate, so it’s important to consider the costs before investing in one.

Summary

Growing mushrooms can be a tricky process (yet rewarding!), and one of the biggest challenges is maintaining the ideal temperature. By maintaining a consistent temperature and humidity level, you can ensure that your mushrooms grow properly and produce high-quality fruiting bodies.
