Oyster mushrooms (Pleurotus spp.) require light to grow and produce sporophores (fruiting bodies). While they do not require direct sunlight, they need exposure to light to initiate fruiting. Inadequate lighting can lead to abnormal growth, with longer stems and smaller caps, as the mushrooms stretch towards the light source. Diffused light, ranging from 500 to 1000 lux for 10 to 14 hours per day, is generally recommended for optimal growth. Artificial light sources, such as LED bulbs, can also be used to provide the necessary lighting conditions.

What You'll Learn
Oyster mushrooms require light to grow
Oyster mushrooms (Pleurotus spp.) require exposure to light to initiate fruiting and produce sporophores (fruiting bodies). A lack of light can impact the development of oyster mushrooms, leading to abnormal growth patterns. In the absence of light, oyster mushrooms may develop longer stems and smaller caps as they stretch towards a light source. The formation of primordia (young mushrooms) can be delayed or inhibited due to insufficient light conditions.
The amount of light required by oyster mushrooms is still a subject of discussion among growers. While some recommend providing light for 12 hours per day, others suggest following the natural day length from sunrise to sunset. Generally, oyster mushrooms perform well with 10 to 14 hours of indirect or artificial light daily. This duration provides the necessary conditions for temperature, airflow, and lighting, promoting the optimal growth of oyster mushrooms.
The intensity and type of lighting also influence the growth of oyster mushrooms. An intensity of 500 to 1000 lux for 12 hours per day is often suggested for oyster mushrooms. LED lights or energy-saving light bulbs are commonly used, with approximately 100 to 150 lumens per square meter (10-15 lumens per square foot). White light is generally preferred, but blue light can also be effective.
Oyster mushrooms are adaptable and can tolerate partial sunlight when grown outdoors. They thrive in diffused natural light, which results in dense clusters with minimal stems and full, fleshy caps. Adequate lighting also enhances the colour, texture, and nutrient content of oyster mushrooms, making them more visually appealing and nutritious.

They need 10-14 hours of light per day
Oyster mushrooms require light to grow and develop properly. While they do not rely on light as a food source, light plays a crucial role in triggering fruiting and guiding their growth. A lack of light can lead to abnormal development, such as longer stems and smaller caps, as the mushrooms stretch towards the light source.
To provide the optimal amount of light for oyster mushrooms, it is recommended to expose them to 10 to 14 hours of light per day. This duration falls within the range suggested by growers, which is generally between 10 and 12 hours of indirect light. You can use natural or artificial light sources, such as LED bulbs, to meet this requirement.
The intensity of light is also important. Oyster mushrooms prefer diffused light with an intensity of 500 to 1000 lux. This can be achieved by placing them near a window or using artificial lighting. In terms of lighting colour, white light is often preferred, but yellow or soft, diffused light can also be sufficient.
It is worth noting that oyster mushrooms are adaptable and can tolerate partial sunlight. They can be grown both indoors and outdoors, making them a versatile species for cultivation. However, direct sunlight should be avoided as it can dry out the mushrooms.
By providing oyster mushrooms with the recommended 10 to 14 hours of light per day, you can ensure their proper growth and development, leading to high-quality yields.

Natural or artificial light can be used
Oyster mushrooms require light to grow and develop properly. While they do not rely on light as a food source, light plays a crucial role in triggering fruiting and guiding their growth. The presence of light can also enhance the colour, texture, and nutrient content of oyster mushrooms.
When using natural light, it is important to ensure that the oyster mushrooms are placed near a window or in an area that receives adequate indirect sunlight. Direct sunlight should be avoided, as it can dry out the mushrooms. A warm spot near a window can provide the necessary lighting conditions and help maintain the ideal temperature and airflow for the mushrooms.
Artificial lighting can be used to supplement natural light or as the primary light source when growing oyster mushrooms indoors. LED lights are commonly used, with white or yellow light being suitable options. The recommended light intensity for oyster mushrooms is 500 to 1000 lux, and they typically require 10 to 14 hours of light per day.
It is worth noting that oyster mushrooms are adaptable and can tolerate partial sunlight or shaded conditions. However, a complete lack of light will hinder their growth, resulting in elongated stems and smaller caps as they stretch towards any available light source. Therefore, providing the right amount of light, whether natural or artificial, is essential for cultivating healthy and robust oyster mushrooms.

They grow well with indirect light
Oyster mushrooms require light to grow and develop properly. While they do not rely on light as a food source, light plays a crucial role in triggering fruiting and guiding their growth.
Oyster mushrooms are sensitive to light, and the amount and type of light they receive can impact their yield, quality, and appearance. They generally require diffused, indirect light to initiate fruiting and grow well. An intensity of 500 to 1000 lux for 10 to 14 hours per day is recommended for optimal growth. This can be achieved through natural or artificial light sources, such as LED bulbs, with white light being preferred by some growers.
When oyster mushrooms are grown in complete darkness, they may still grow, but their development will be impacted. They may develop longer stems and smaller caps as they stretch towards a light source. The colour, texture, and density of the mushrooms can also be affected, resulting in a less appealing product. Therefore, providing indirect light is crucial for the healthy growth of oyster mushrooms.
To create optimal growing conditions for oyster mushrooms, a warm spot near a window with indirect light is ideal. This setup provides the necessary temperatures, airflow, and lighting for their development. Additionally, maintaining high humidity levels by misting the mushrooms with water is essential.
While oyster mushrooms thrive with indirect light, they can also tolerate partial sunlight. They can be grown outdoors, where they can handle varying light conditions, including full sun. However, direct sunlight should be avoided during the fruiting phase, as it can dry out the mushrooms.

Mushrooms don't need direct sunlight
Mushrooms, including oyster mushrooms, do not require direct sunlight to grow. Mushrooms are not plants and do not rely on photosynthesis, so they do not need sunlight in the same way that plants do. Instead, mushrooms require diffused, indirect, or artificial light to grow.
Oyster mushrooms (Pleurotus spp.) require light to initiate fruiting and produce sporophores (fruiting bodies). This light can be natural or artificial, as long as it is in the right spectrum (white or blue light). An intensity of 500 to 1000 lux for 12 hours per day is often recommended for oyster mushrooms. This can be achieved with LED or energy-saving light bulbs.
While oyster mushrooms do not require direct sunlight, they will not grow well in complete darkness. A lack of light can impact the development of mushrooms, causing longer stems, smaller caps, and uneven pigmentation. Adequate exposure to light can improve the colour, texture, and nutrient content of oyster mushrooms.
It is important to note that oyster mushrooms can tolerate partial sunlight and even full sun in some cases. However, too much direct sunlight can dry out the mushrooms. Therefore, it is best to provide indirect or artificial light for oyster mushrooms, rather than direct sunlight.
In summary, while mushrooms, including oyster mushrooms, do not require direct sunlight, they do need indirect or artificial light to grow and develop properly. Growers can provide this light using LED or energy-saving light bulbs, following the recommended intensity and duration guidelines for optimal mushroom growth.
