Blue light, which has a wavelength between 320 to 500 nm, has been shown to promote faster colonization times and higher yields of fruiting bodies in some mushroom species. Blue LED lights can aid a range of species, from oyster to shiitake, in producing high-quality yields. Blue light mimics the natural conditions under which many mushrooms grow, signalling to them that they are near the surface and triggering the fruiting phase. However, it is important to note that light is not universally beneficial for all mushrooms, and some, like enoki mushrooms, grow better in complete darkness.

What You'll Learn
Blue LED light can increase mushroom yield
Blue LED light, specifically the Blue Sun Spectrum offered by Active Grow, can aid a range of species from oyster to shiitake and lion's mane in producing bountiful and high-quality yields. It is tailored for mushroom growth, focusing on the 450 nm blue wavelength, which is particularly beneficial for initiating the fruiting phase. Blue light mimics the natural conditions under which many mushrooms grow. In the wild, mushrooms are exposed to blue light in daylight. This exposure can signal to the mushrooms that they are near the surface, triggering them to begin fruiting.
Paul Stamets, a renowned mycologist, discusses the influence of blue light on the formation and yield of mushrooms. He highlights that blue light with a wavelength of 320 to 400 nm stimulates mushroom formation. Additionally, he mentions that exposing magic mushrooms to blue light increases the amount of psilocybin and psilocin, substances that contribute to the effectiveness of a gram of mushrooms.
It is important to note that light intensity plays a crucial role in mushroom development. Insufficient light can lead to slow or stunted growth, while too much light can cause stress and negatively impact yields. The ideal light intensity and duration depend on the specific mushroom variety and growth stage. Most mushrooms require 12-16 hours of light per day, along with a consistent dark period for rest.
Full spectrum LED grow lights are a preferred choice for mushroom cultivation as they provide the necessary blue and red light wavelengths for optimal growth. These lights are energy-efficient and suitable for all mushroom types and growth stages. Customized spectrum LED lights can be adjusted to provide specific light spectrums, allowing growers to tailor the light to their mushroom's needs.

Blue light stimulates mushroom formation
Blue light, with a wavelength of 320 to 500 nm, has been found to stimulate mushroom formation and promote faster colonization times and higher yields of fruiting bodies in some species. In his presentation for Exponential Medicine, Paul Stamets, perhaps the world's most famous mycologist, explains that Psilocybe cubensis (magic mushrooms) need four things to grow mushrooms from the mycelium, and that blue light influences the formation and yield of mushrooms.
Blue light mimics the natural conditions under which many mushrooms grow. Mushrooms are often exposed to blue light in daylight, signalling to them that they have reached the outer limits of their growing medium or that they are near the surface, triggering them to begin fruiting. Blue light has also been found to influence the concentration of antioxidants and other beneficial compounds in mushrooms, enhancing their nutritional profile, flavour, and shelf life.
The Blue Sun Spectrum offered by Active Grow can aid a range of species, from oyster to shiitake and lion's mane to psylocibin, in producing bountiful and high-quality yields. This technology focuses on the 450 nm blue wavelength, which is particularly beneficial for initiating the fruiting phase. The integration of the 450 nm blue wavelengths with broad-spectrum white light allows for a more balanced approach to mushroom cultivation.
However, it is important to note that light is not universally the best choice for all mushrooms. Some mushrooms, like enoki, can be grown in complete darkness, and exposure to light may lead to undesirable traits for culinary applications. Additionally, excessive light exposure can cause drying out, bleaching, and even the death of mushrooms, so finding the right balance is crucial for successful cultivation.

Blue light affects mushroom pigmentation
Blue light, with a wavelength between 320 to 500 nm, has been shown to promote mushroom growth and induce morphological changes in mushrooms. In nature, mushrooms are often exposed to blue light present in daylight, which signals to them that they have reached the outer limits of their growing medium or are near the surface, triggering the fruiting phase.
The Blue Sun Spectrum LED technology offered by Active Grow focuses on the 450 nm blue wavelength, which is beneficial for initiating the fruiting phase. This technology is tailored for mushroom growth, incorporating 6500K Correlated Color Temperature (CCT) white high Color Rendering Index (CRI) chips to cover the entire spectral range, including far-red wavelengths.
Studies have found that blue light influences the formation and yield of mushrooms, with some species exhibiting faster colonization times and higher yields of fruiting bodies when exposed to blue light. For example, oyster mushrooms grown under blue light produced a higher fresh weight compared to those grown in darkness or red light.
Additionally, blue light has been shown to increase the pilus diameter and stipe thickness of certain mushrooms, such as Lentinula edodes (LE). Blue LEDs have also resulted in higher commercial yields of Hypsizygus marmoreus, with an increase in the yield of the fruit body reported when cultivated under 340~520 nm light.
While blue light can be beneficial for many mushroom species, it is not universally suitable for all. For example, enoki mushrooms, a delicate variety, can be grown in complete darkness, resulting in longer and thinner mushrooms, which is desirable for culinary applications.

Blue light influences mushroom protein expression
Blue light, with a wavelength of 320 to 500 nm, is an important environmental factor that influences mushroom growth and morphological changes. It has been found to promote faster colonization times and higher yields of fruiting bodies in some mushroom species. Blue light mimics the natural conditions under which many mushrooms grow, signalling to them that they have reached the outer limits of their growing medium or are near the surface, triggering the fruiting phase.
Several studies have investigated the impact of blue light on the expression of proteins in mushrooms, specifically the edible mushroom Lentinula edodes (LE). These studies compared the expression patterns of proteins in LE grown under blue light (BL) and lightless (LL) conditions using methods such as 2D electrophoresis, LC-MSMS analysis, and Quantitative Real-Time PCR.
The results of these studies revealed that blue light influenced the expression of proteins in LE. Specifically, it was found that 14 types of proteins showed reduced expression in BL compared to LL, while eight types of proteins showed increased expression. However, the expression of transcripts and protein expression was not found to be a key factor directly inducing morphological changes. Instead, the significance of these studies lies in their exploration of proteins and transcriptomes related to the photoreactivity of LE.
The intensity of blue light-emitting diodes (LEDs) also influences the antioxidant properties and sugar content of oyster mushrooms (Lentinus sajor-caju). Higher light intensities result in increased antioxidant capacity and soluble sugar content. Precise management of blue LED intensity may offer the potential to enhance the nutritional value of edible mushrooms cultivated in controlled environments.

Blue light is not suitable for all mushrooms
Blue light, which has a wavelength between 400 and 500 nm, appears to promote faster colonization times and a higher yield of fruiting bodies in some mushroom species. Blue light mimics the natural conditions under which many mushrooms grow. In the wild, mushrooms are often exposed to the blue light present in daylight. This exposure can signal to the mushrooms that they have reached the outer limits of their growing medium or that they are near the surface, triggering them to begin fruiting.
Blue light is an important environmental factor that induces mushroom growth and morphological changes. Blue light with a wavelength of 320 to 400 nm stimulates mushroom formation. However, these wavelengths belong to invisible ultraviolet light, so it is crucial to pick the right lighting. Blue LED light, specifically the Blue Sun Spectrum, can aid a range of species from oyster to shiitake and lion's mane in producing bountiful and high-quality yields.
However, it is important to note that while light can be beneficial for many mushroom species, it is not universally the best choice for all mushrooms. For example, some mushrooms, like the delicate enoki, can be grown in complete darkness. In the case of enoki mushrooms, the absence of light encourages them to grow longer and thinner, which is a desirable trait for this particular variety. When exposed to light, enoki mushrooms may develop a larger size, which is not preferred in culinary applications.
Additionally, oyster mushrooms grow better in red light than in blue light, and shiitake mushrooms grow best in green light. The color of the light and the wavelength can have different effects on mushroom growth. Light just tells mushrooms which way to grow, and they get their nutrients from the substrate.
