Blue Light is a term commonly used in cannabis cultivation. It refers to the specific spectrum of light emitted by certain types of grow lights, such as metal halide (MH) or fluorescent lights. Blue light has a wavelength of around 400-500 nanometers and is known to promote vegetative growth in plants. This type of light is crucial during the early stages of cannabis growth as it helps stimulate leaf and stem development. Blue light also plays a role in regulating plant morphology and overall plant health. Cultivators often use blue light in combination with other light spectrums to create optimal growing conditions for cannabis plants.
