Led grow light wavelength of light

Wavelength of visible light is between 380nm to 750nm wavelength below 380nm is called ultra-violet (UV) wavelength and the higher the energy that can be harmful to plants, only about 5% of the UV light and usually covered greenhouse. Reduce the more. It should be noted that some of the artificial light sources generate UV light LED grow lights.

Synthesis is driven by light. By the wavelength of 400nm to 700nm range, which is about 50% of the solar radiation. Below this range. photosynthetic. Colors absorb light better. And adequate to support the needs of high-energy wavelengths of light for photosynthesis, plants use light from the led grow lights mark a major development environments. Plants use the color of the light receiving them by phytochrome Phytochrome participation in terms of plant development. Including the regulation of stem elongation growth and sometimes Power Engineering.

Leaves absorb wavelengths above 700nm is the most efficient because the pigment. photosynthetic. But do not absorb well in the range 700nm 860nm (Ps. LED grow lights can emit full spectrum light for all phases of plant growth) and plant color. Water inside plant tissues absorb infrared (IR) light areas. Only a small fraction of the absorbed light energy is dissipated by absorption of plant metabolism. Most of which is dissipated by evapotranspiration. Heat loss by convection. And long wavelength re-radiation (> 3000nm).

LED grow lights are the most efficient type of growth, which can be purchased. Compared to HID or LED grow lights, fluorescent grow lights can save 70-80% in electricity costs and do not contain any harmful substances in the environment.
