Effect of Cannabis LED Grow Light On Growth Process
The sun emits energy in the shape of radiation. After that, this radiation goes through an ozone layer for filtration, allowing 300nm to 1100nm wavelengths for plants. We call this light a color spectrum, visible spectrum, or light spectrum. The spectrum consists of various colors, including violet, blue, indigo, yellow, orange, green, and red. This spectrum is critical in building levels of THC in marijuana. But when it comes to growing cannabis indoors, cannabis LED grow light fixtures replace sunlight. LED grow lights are available in different colors to encourage substantial cannabis growth. However, you must choose the most suitable spectrum for your plants.
When buying a grow light for your plant, you must make sure whether or not the light color will affect the plant growth. Usually, red and blue are the most suitable colors for indoor plants growth. Green and yellow are known as the least beneficial colors. However, different colors are necessary at different stages. Read this article to understand the effects of cannabis grow light on cannabis plant growth.
What is Cannabis LED Grow Light Color Spectrum?
The grow light color spectrum is the light’s electromagnetic wavelengths caused by the source of light. This light spectrum is known for encouraging plant growth. A plant requires light in the 400nm to 700nm PAR wavelength range for photosynthesis. Therefore, taking care of the light spectrum is very important. To cultivate marijuana, light plays an essential role. Different colors of spectrums play different roles in the growth and development of cannabis. It is the reason why we need to pay special attention to the cannabis LED grow light color spectrum. The effect of grow lights on plants may differ according to different environmental conditions.
Normally, chlorophyll absorbs the most light in blue and red light spectrums to photosynthesize. Chlorophyll converts the energy of light to chemical energy. You will find these lights at the PAR’s top range. Cannabis collects massive information through the light spectrum and responds to different light wavelengths in dissimilar ways.
You can choose blue light between 400nm to 500nm for cannabis in its vegetative stage. The most ideal range for this stage is 460nm. In the vegetative stage, the plant will get signals to grow healthy and strong with large leaves. For the flowering stage, you should choose the red light between 620nm to 780nm for the best possible yields. If you choose the grow light color spectrum of wavelength 660nm, it will impact the plant growth and photosynthesis rate.
Different Light Colors
Typically, we divide an electromagnetic spectrum into 7 different categories. The increasing energy and frequency and decreasing wavelengths order help in categorizing the colors. We have UV (Ultraviolet), Gamma rays, Microwaves, Visible light, X-rays, and infrared (IR). Out of these categories, the visible light color spectrum consists of the following colors:
The light wavelengths for all these lights are unique. The violet light comes with 425nm to 400nm wavelength which is the shortest of all. The atmosphere scatters it successfully. Indigo light has 450nm to 425nm wavelength. This color falls between violet and blue. Blue light color has a 500nm to 450nm wavelength. Green has 570nm to 500nm wavelength while the orange and yellow range from 610nm to 590nm and 590nm to 570nm, respectively. You can view the red light during the sunsets and sunrises and its wavelength is between 750nm to 610nm.
It is a very common question that does the cannabis LED grow light color spectrum affects the growth of plants? Cannabis is suitable for many recreational and medicinal purposes. Therefore, several countries and states have allowed cannabis cultivation and use. In countries, such as the USA, it is legal to grow cannabis at home. So, the growers of cannabis must understand how the grow color light will affect the marijuana plants’ growth.
How Grow Light Color Spectrum Affects the Growth of Cannabis?
You cannot ignore the light color spectrum factor while creating the most suitable environment for cannabis cultivation. Many growers have several goals, such as achieving greater plants yields and increased THC levels. Maintaining and improving the plants’ overall health for indoor growth is critical. Rational growers must do proper planning and come up with reliable technical solutions for achieving their objectives. They must understand that sufficient light is a critical factor when growing cannabis plants. Grow light colors are the special tools for producing more buds.
Cannabis is a highly light-sensitive plant and you must adjust the grow light color, frequency, and intensity for different stages of growth. You can get closer to the natural lighting conditions by using cannabis LED grow light. We get a complete light spectrum in natural sunlight. With the seasonal change, the energy of wavelength also changes. The sunlight during summers has heavy blue and green wavelengths. It is redder during the fall. When growing cannabis indoors, you should try to achieve the closest natural seasonal variations. It means that you must use grow lights with varying colors to boost cannabis growth.
For cannabis cultivation, feminized seeds of cannabis are important. It is because only the female cannabis plant can grow consumable flowers. With a grow light, you can boost the profits and sustainability of cannabis.
There is an assortment of grow light fixtures available on the market. Every single type of grow light comes with its unique advantages and disadvantages. Most grow lights can offer your different light colors, known as the light temperature. As a grower, you must perform proper research before buying grow lights for your cannabis plants. As we discussed above, light spectrums differ in their effects on marijuana growth. Therefore, you can consider different grow light colors for different stages of indoor plants growth. Remember that excess grow light can also damage your plant. Therefore, you must understand how to treat your plants with proper grow lighting fixtures.
