Plant growth lamps for indoor planting lighting

Planting family plants and seedlings in summer cabins is not just about saving souls. I hope these plants are sturdy, healthy, and can please along with leaves, flowers, and fruits. In our environment, it is impossible to always achieve this without additional effort. The main problem is the short daylight hours. Make it backlit. And there is a special plant growth lamp for this. They are also known as growth lights, agricultural lamps (agricultural planting lights). There are enough names, but they are essentially the same - they are the light sources that make plants grow, bloom, and bear fruit better.
What is a plant growth lamp and how is it different from regular lamps?
For the growth and development of plants, specific parts of the spectrum of light waves are required. In our color perception, this is the light within the red and blue range. The blue part of the spectrum has a wavelength of 420-460 nm, and the red part has a wavelength of 630-670 nm. Plants require the rest of the spectrum, but in much smaller quantities.
When planting seedlings and maintaining greenhouses, plants will "illuminate" - they use additional lighting to extend daylight hours. You can use regular lamps for this operation, as 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 the required length. Therefore, theoretically, they will be more economical than conventional backlighting. In fact, the unnecessary spectrum of plants consumes less energy. This type of light source is also known as agricultural lamps. They not only sell individual light bulbs, but also the entire lighting fixture. They are also known as plant growth lights, also known as plant fill lights. But the essence is the same - in this type of light source, there is a large amount of red and blue light.
There are two types of growth lamps. Some gas discharge gases have a complete spectrum, but their difference lies in their higher radiation intensity within the required range. This is reflected in the spectrum of this light source. The second type of lamp is narrow band fluorescent lamp and LED. You can distinguish it from traditional light sources. Due to its main red and blue spectra, it emits purple light.
