A Comprehensive Overview On The Use Of LED Grow Lights In Crop Production

By Cynthia Hayes


LED is used as an acronym for Light Emitting Diodes. There are major differences between the diodes used in agriculture and those present in most electrical devices. The lighting power of agricultural diodes is effectively adjusted by changing proximity of the diodes accordingly. This information aims to elaborate further on LED grow lights.

For LEDs a single wavelength can be emitted as required. This is not however the case for the common light bulbs. These bulbs emit a wide range of wavelengths which form the final white light by combining the wavelengths together. Power adjustments are done by increasing the number of diodes or even by controlling the brightness of these diodes.

Numerous studies have been commissioned with the aim of gaining an understanding on the effect the sun gives to plants. The benefits availed by the sun are sometimes overshadowed by the fact that chlorophyll formation is greatly reduced in its presence. This is as a result of some wavelengths it produces. For this reason the adoption of LED technology became necessary to counter this.

This technological advancement came to help allow people to grow crops even in areas with the minimum exposure to the sun. This is seen to pose a challenge to the growth of plants as chlorophyll production cannot take place in those conditions. Some localities also never have enough space for growing their plants in the outdoors. This makes them seek for alternative farming areas indoors.

Wavelength absorption is facilitated by the fact these diodes can be put close to the plants. This action will have no adverse effects to crops as there will be no cases of excess heat damaging plants. The overall effect of this action is that the development of the plant is experienced to be stimulated.

This technology has a very big effect in the preservation of the water resources. The cool temperature present in the growing space due to the use of diodes reduces the amount of water lost by plants from transpiration. This technology also makes the height of a plant controllable as it only requires the plant to be moved to and from the diode.

Conventional lighting solutions have been found to increase the energy bills. The major contributing factor to this is their bulky components which require a lot of energy for operation. These components are known as ballasts and they are tasked with the responsibility of ensuring that the system does not ruin itself. This challenge has been effectively solved by the emergence of diodes.

The intensity that the wavelengths are transmitted to the plants is easily adjustable by controlling the degree of brightness produced by the diodes. Scientists have also associated the increase in the anti-oxidation abilities of plants to ability to vary the intensity of the wavelength. For agricultural purposes one should consider the different benefits availed by the different products in the market. The energy consumption should be determined to be efficient and the unit should have the ability to cool itself. The spectrum produced must be deemed suitable for that very purpose.
