With legalization in some states, the use of cannabis has become more and more popular, and many people are growing their own plants at home. As we know, cannabis plants need light in order to thrive, and in particular, ultraviolet (UV) and far-red (FR) lights. In this article, we will explore the effects of UV and FR lights on the growth, development, and overall quality of cannabis.


UV Light

UV light is a type of light that is present in the electromagnetic spectrum between visible light and X-rays. It is often associated with its ability to cause sunburn and skin damage, but it also plays a critical role in the growth and development of plants.
In cannabis cultivation, UV light has been shown to increase the production of trichomes, which are the glandular hairs on the leaves and buds that contain the plant's medicinal and psychoactive compounds. This increased trichome production can lead to a higher potency and overall quality of the final product. Additionally, UV light has been shown to enhance the plant's natural defenses, making it more resistant to diseases, pests, and environmental stressors.


FR Light

FR light is a type of light that is located at the far-end of the red spectrum, just beyond the visible spectrum. It is often considered a "cryptochrome light" because it is absorbed by certain pigments in plants and regulates various physiological processes.
In cannabis cultivation, FR light has been shown to play a critical role in the photoperiod response of the plant, which is its ability to detect changes in the length of daylight and adjust its growth and flowering accordingly. By exposing the plant to FR light during its vegetative phase, growers can encourage the plant to remain in a vegetative state for longer periods, leading to larger and healthier plants.
However, too much FR light can have a negative effect on the plant, causing it to stretch and become lanky, resulting in reduced yield and quality. It is important to find the right balance between the right amount of FR light and other environmental factors such as temperature, humidity, and nutrition.

In conclusion, UV and FR lights play a critical role in the growth, development, and overall quality of cannabis. By understanding the effects of these lights, growers can optimize their cultivation environment to produce high-quality and potent cannabis. Hortibest’s Moray-H10 is equipped with UV+FR light which can help to add extra UV and FR lights for cannabis grow.
