Legal marijuana cultivation is mostly indoor. LED cannabis lighting is an indispensable growing condition for cannabis in the enclosed indoor environment where sunlight is scarce. There are a wide variety of growth lights on the market with different functions. In order to find suitable cannabis growth lights, we must have an in-depth understanding of the effects of LED plant growth lights on cannabis growth. Therefore, we have to study the effects of different spectra on cannabis growth.
What is spectrum?
Natural light consists of many different colors of light. The combination of light causes the natural light we see to appear white. The wavelength of different colors of light is different, and the Angle of refraction into the medium is different. According to this property of light, natural light passes through a prism. We can see that white light is divided into a continuous spectrum of different colors, which is the visible component of white light.
After many years of research, the growth of plants is closely related to the changes of the external environment. Sunlight is one of the most important factors. Sunlight not only brings energy and signals to plant growth, but also regulates the state of plant growth. Natural light conditions are difficult to control. As a result, growers have no control over the growth of outdoor plants. With the development of agricultural technology, many crops are now grown in indoor environments. Growers can adjust nutrients, carbon dioxide concentrations and spectra to allow crops to grow in the direction they want them to.
