What is plant growth lamp? What is the difference between it and the ordinary one?

For the growth and development of plants, light waves in specific parts of the spectrum are needed. In our color perception, this is light in the range of red and blue. The wavelength of the blue part of the spectrum is 420-460 nm and the wavelength of the red part is 630-670 nm. Plants need the rest of the spectrum, but in much smaller quantities.

During seedling and greenhouse maintenance, plants "light up" - they use additional lighting to prolong daylight time. You can do this with ordinary lamps because their spectra also contain the required range of light radiation. The difference between plant growth lamps is that the spectrum is mainly composed of waves of required length. Therefore, theoretically, they will be more economical than conventional backlights. In fact, the "unnecessary" spectrum of plants consumes less energy. This light source is also called agricultural lamp. They sell not only individual bulbs, but also whole lamps. They are also known as plant growth lights, or plant light bulbs. But the essence is the same - in this light source, there are a lot of red and blue light.

There are two types of growth lights. Some gas discharge gases have the entire spectrum, but their difference is that the radiation intensity is higher in the required range. This is reflected in the spectrum of this light source. The second type of lamp is narrow section fluorescent lamp and led. You can distinguish it from traditional light sources by. Because it mainly has red and blue spectra, it emits purple light.
