The Role Of LED Lights In The Horticulture Industry

With their capability to precisely control spectral composition, ensure low heat emission and deliver effective light output for years on end, without the need for frequent replacements, LED lights are set to transform the horticulture industry.

The dependence on horticulture lighting is increasing every year with the burgeoning population and the scarcity of agricultural land. Thanks to LED technologies, indoor and vertical horticulture are both possible now, even without natural sunlight. As a result, the demand for LEDs has shot up, considering their unique advantages in comparison with existing horticultural lighting.

While energy efficiency has been the major reason behind the increasing adoption of LED technologies, there are other benefits that give it an extra edge over traditional lighting options. In horticultural farming, light plays an important role in promoting the growth of the plant, regulating about 90 per cent of a plant’s genes. LEDs have the capability to control the light’s spectral composition precisely, which can influence plant growth and morphology.

How LED lighting is ideal for horticulture

LED based horticultural lighting comprises the light-emitting diodes, usually available in a casing with a heat-sink and built-in fans. In such lighting systems, a ballast is not required separately, and can be inserted directly into a standard electrical socket. Functionally, when there is no sun, these lights are used as a source of daylight, which leads to the normal growth of the plants. They not only enhance the taste and quality of the fruits or plants, but also make it possible to produce higher yields in a shorter time. LED lighting has a wide light spectral output that delivers the varied spectral requirements of different plants. This lighting provides the intensity and colour spectrum as per the needs of different plants, which fuels plant growth.
