In the visible light spectrum, the wavelength of red light ranges from about 620nm to 750nm. Compared to 660nm bright deep red light, 730nm far red light is closer to the boundary of infrared light.
730nm led grow light
730nm light promotes shade avoidance, makes plants taller, and regulates flowering cycles. This wavelength of red light also penetrates deeply into the plant canopy, which enhances photosynthesis and is especially beneficial for ornamental flowers.
