Mushrooms are fungi, not plants, so they don't require light for photosynthesis. However, light plays a crucial role in the growth and development of mushrooms by providing a source of energy. The amount of light required varies depending on the mushroom species, with some mushrooms thriving in low light conditions and others requiring more intense illumination. While some mushrooms can grow in the absence of light, most mushrooms require at least some indirect sunlight or artificial light to develop mature fruiting bodies. The duration of light exposure also varies, with some mushrooms requiring only a few hours of light per day, while others benefit from 10 to 12 hours of light. The intensity and spectrum of light also influence mushroom growth, with blue light promoting vegetative growth and red light stimulating reproductive structure formation. Overall, finding the right balance of light exposure is essential for successful mushroom cultivation.

Mushrooms need light to grow
Mushrooms are fungi, not plants, so they don't require light for photosynthesis. However, light plays a vital role in the growth and development of mushrooms. The amount of light mushrooms need varies depending on their growth stage and species.
At the spore stage, mushrooms require almost no light, which can be entirely ignored. The mycelium stage, or the roots of the mushroom, requires around 4 hours of low light to support healthy growth, but this is not necessary. During this stage, mushrooms are usually kept in the dark or with very little light to allow the mycelium to spread out and connect.
At the fruiting body stage, mushrooms need 4-6 hours of indirect light per day with moderate intensity. This light helps the mushrooms generate the energy needed to carry out essential metabolic activities. Light exposure also ensures mushrooms have a more even colour and better form. For example, oyster mushrooms develop a more balanced cap colour and stem thickness under moderate light.
Some mushroom species require no light at all to grow, such as the Psilocybe Albino, which prefers almost complete darkness. Other species, such as the psychedelic Psilocybe Cubensis, require plenty of light to develop healthy, mature fruiting bodies.
For indoor growing, natural diffused light is ideal. If your space lacks natural light, LED grow lamps are a great alternative as they simulate natural sunlight and protect mushrooms from excessive heat or radiation. The wattage and intensity of the light should be lower, and the light should not be too strong. Blue light promotes vegetative growth, while red light stimulates the formation of reproductive structures.

Natural light is good for mushrooms
When growing mushrooms, it is recommended to avoid direct sunlight as it can be harmful. Instead, indirect sunlight or ambient light from a window is often sufficient. This natural light source provides the necessary illumination for the mycelium to develop mature fruiting bodies. Growers can place their terrarium or grow kit near a window to benefit from this natural light without risking overexposure.
The amount of natural light mushrooms require can vary. Some sources suggest that 4 to 6 hours of indirect light per day is adequate for the fruiting body stage, while others recommend 10 to 12 hours of light daily. It is important to monitor the mushrooms' development and adjust the lighting conditions if needed.
Using natural light to grow mushrooms offers several advantages. Firstly, it is cost-effective and convenient as it eliminates the need for artificial lighting equipment. Natural light also simplifies the growing process by removing the need to determine lighting schedules and intensities. By relying on natural light, growers can focus on other critical aspects of mushroom cultivation, such as humidity and temperature control.
While natural light is beneficial, it is worth noting that mushrooms do not depend on photosynthesis for growth. Their light requirements are relatively low, and they can even grow in shady spots in forests. However, proper light exposure plays a crucial role in ensuring mushrooms develop an even colour and maintain their ideal form. Therefore, when using natural light, it is important to ensure that the mushrooms receive an adequate amount to support their growth and development.

Artificial light can be used
Mushrooms do not rely on photosynthesis, meaning they do not depend on light for their nutritional needs. They can grow in complete darkness, absorbing nutrients from their surrounding environment. However, light can be used as a directional cue, helping mushrooms grow towards a light source and exposing their spore-bearing surfaces optimally for spore dispersal.
There are different types of artificial lighting that can be used for mushroom cultivation. Fluorescent (CFL) lighting is a popular choice among growers, as it is energy-efficient and provides the desired light spectrum. LED lamps are also an option and offer modern and efficient lighting for mushrooms. It is important to avoid incandescent light bulbs, as they emit a "red" light in the low range of 3000-3500 Kelvin, which is not ideal for mushroom growth.
When using artificial light, it is crucial to ensure that the lighting is not placed too close to the mushrooms, as this can cause overheating or even burns. Additionally, excessive heat can prevent fruiting bodies from fully germinating. By maintaining a suitable distance and monitoring for burn damage, growers can optimise the benefits of artificial lighting while minimising potential drawbacks.
Overall, artificial light plays a significant role in mushroom cultivation, providing directional cues and contributing to the uniform growth of mushrooms. With the ability to control lighting conditions, growers can create optimal environments for their mushrooms, promoting healthy and productive yields.

The amount of light depends on the mushroom species
The amount of light a mushroom needs depends on the species. While some mushrooms can be grown in the dark, others require light to grow. For instance, the Psilocybe Cubensis, also known as the Mexican mushroom, grows well in bright light. On the other hand, the Psilocybe Albino hardly needs any light and prefers it to be almost completely dark.
Mushrooms are fungi, not plants, so they don't rely on photosynthesis for growth. However, light plays a crucial role in the growth environment of mushrooms. Proper light exposure ensures mushrooms have a more uniform colour and better form. For example, oyster mushrooms develop a more balanced cap colour and stem thickness under moderate light. Without enough light, mushrooms may become elongated or deformed, and their growth rate may be impacted.
The light requirements for mushrooms also depend on the growth stage. During the mycelium stage, around 4 hours of low light can support healthy mycelium growth, but this is not mandatory. At the fruiting body stage, mushrooms require 4 to 6 hours of indirect light per day with moderate intensity. However, the specific light requirements vary depending on the type of mushroom being grown. Enoki, oyster, straw, and button mushrooms typically need 4 to 6 hours of light daily, while shiitake, reishi, lion's mane, and chanterelles may require 10 to 12 hours.
When choosing a light source, it is essential to consider the light spectrum and heat output. Mushrooms are best suited to a colder light that leans towards the blue end of the spectrum, typically in the 6,000 to 7,000 Kelvin range. LED lights are a popular choice as they are energy-efficient and can simulate natural sunlight while protecting mushrooms from excessive heat.

Light intensity and duration are important
Light is not essential for mushroom growth, and their light requirements are relatively low. However, light does play a significant role in the growth environment of mushrooms. Proper light exposure ensures that mushrooms develop an even colour and maintain their ideal form. For example, oyster mushrooms achieve a more uniform cap colour and balanced stem thickness when exposed to moderate light.
The amount of light required varies depending on the type of mushroom. For instance, enoki, oyster, straw, and button mushrooms typically require only 4-6 hours of light daily. On the other hand, varieties like shiitake, reishi, lion's mane, and chanterelles may need 10-12 hours of light each day.
The intensity of the light is also important. Lamps with higher Kelvin ratings emit a stronger light. Lights measuring below 7,000 Kelvin are generally safe to leave on for longer periods, whereas lamps above 7,000 Kelvin can harm mushrooms if left on for too long.
The duration of light exposure is crucial as well. A consistent amount of light at set intervals is necessary to establish a stable growth cycle. During the mycelium stage, around 4 hours of low light can support healthy mycelium growth, but this is not mandatory. At the fruiting body stage, mushrooms require 4-6 hours of moderate-intensity, indirect light per day.
In summary, while mushrooms have relatively low light requirements, light intensity and duration play a significant role in their growth and development. By mastering these light conditions, cultivators can easily grow well-formed, healthy mushrooms.
