Plant growth lamp

- May 17, 2019-

A plant growth lamp is an artificial light source, usually an electric one, designed to stimulate plant growth by emitting an electromagnetic spectrum suitable for optical cooperation. Plant lamps are used in applications where there is no natural light or where supplementary light is required. For example, in winter, lights are used to extend the time plants receive light when possible daylight hours may not be sufficient for the required plant growth. If plants do not get enough light, they will grow in vain.

The growing lights either attempt to provide a spectrum similar to that of the sun, or provide a spectrum more suitable for the needs of the cultivated plants.

Simulate outdoor conditions from increasing the lamp's different colors, temperature and spectral output, as well as changing the lamp's lumen output (intensity). Depending on the type of plant being cultivated, the stage of cultivation (e.g., germination/vegetative stage or flowering/fruiting stage) and the photoperiod required by the plant, the specific range of the spectrum, luminous efficiency and color temperature are desirable for specific plants and time periods.

In 1868, Russian botanist Andrei Famintsyn was the first to use artificial light for plant growth and research.
