'<p style="line-height: 1.75em;">The response of cannabis plants to the spectrum is mainly reflected in the effects of different spectral components on their growth. The response mechanism of cannabis plants to the spectrum is closely related to the light changes in the natural environment. The spectral changes in different seasons will affect the growth state and physiological changes of cannabis.</p><p><br/></p><p style="line-height: 1.75em;"><strong>Specific effects of different spectral components on cannabis growth</strong></p><p style="line-height: 1.75em;">Blue light (400-500nm): Blue light is essential for the growth and development of cannabis plants. During the growth stage, plant growth lamps with a high proportion of blue light can make cannabis plants stronger, with thick stems and lush leaves. Blue light also affects the directional growth of plants, making them grow towards the light source.</p><p><br/></p><p style="line-height: 1.75em;">Red light (620-780nm): Red light is particularly important for the growth of cannabis plants during the flowering period. Grow lamps with a high proportion of red light can promote flowering and yield of cannabis plants. Red light helps plants leave more space between leaves and promotes the formation and development of flower buds.</p><p><br/></p><p style="line-height: 1.75em;">Ultraviolet light (UVA/UVB): The ultraviolet spectrum also has a certain effect on cannabis plants. While high-intensity UV rays can harm plants, moderate amounts of UV-B light may increase the THC content or other active ingredients in cannabis. However, the specific effects are unclear because there are few studies on the subject.</p><p><br/></p><p style="line-height: 1.75em;"><strong>Physiological mechanisms of cannabis plant response to spectrum</strong></p><p style="line-height: 1.75em;">Cannabis plants regulate their growth and development by sensing spectral changes in their surroundings. In spring and summer, more blue light reaches the plants, prompting them to grow lush leaves and short stems. With the arrival of autumn, the increase in red light prompts the plants to enter the flowering period, prompting them to grow taller and promote the formation of flower buds. This mechanism of sensing and responding to the spectrum helps cannabis plants adjust their physiological state at different growth stages to adapt to environmental changes.</p>'
