Two major effects of 730nm far-red LED on plants 1. 730nm far-red light's shade avoidance effect One of the most important effects of 730nm far-red light illumination on plants is shade avoidance (Figure 3). If the plant is only irradiated by the deep red light of 660nm, the plant will feel that it is under direct sunlight and grow normally. And if the plant is mainly irradiated by the far-red light of 730nm, the plant will feel as if it is blocked by another taller plant from the direct light of the sun, so the plant will grow harder to break through the obscuration. Helping plants grow taller, but it does not necessarily mean there will be more biomass (bio mass). 2. Flower inducing effect of 730 nm far-red light Another important role of 730nm far-red light in horticultural lighting applications is that the flowering cycle can be controlled by 660nm and 730nm lighting, without relying only on the influence of seasons, which has important value for ornamental flowers. The convers...

Light has a particularly important position in the growth and development of plants, and it affects almost all growth stages of plants. The effects of light on plants are mainly manifested in two aspects: One is to provide radiant energy for plant photosynthesis. The second is as a signal to regulate many physiological processes throughout the life cycle of plants. The effect of light on plant growth-photosynthesis and phytochrome Generally, the growth and development of plants rely on sunlight, but the factory production of vegetables, flowers and other economic crops, tissue culture, and the propagation of test-tube seedlings also require supplementary light from artificial light sources to promote photosynthesis. Photosynthesis refers to the process by which green plants use light energy through chloroplasts to convert carbon dioxide and water into organic matter that stores energy and release oxygen. The key participant in this process is the chloroplast inside the plant cell. U...

Is LED grow lights harmful to human body? Yes, LED grow lights are harmful to humans(To be precise, the eyes). The LED plant light source is mainly composed of red and blue light sources, using the most sensitive light band of plants, and the blue light wavelengths are 450-460nm and 460-470nm. Blue light is light with relatively high energy in the wavelength range of 400nm-480nm. It is abundant in computer monitors, fluorescent lamps, mobile phones, digital products, display screens, LEDs and other light. Blue light within this wavelength will cause the macular area in the eye. The increased amount of toxins seriously threatens the health of our eyes(If you face these lights for a long time). The led lamp can directly convert electrical energy into visible light and is a solid-state semiconductor device. The part used for led is a semiconductor chip, one end of this chip is attached to a bracket, one end is connected to the positive pole of the power supply, and the whole ch...
