A Definitive Guide On LED Grow Lights

By Cynthia Hayes


LED stands for Light Emitting Diodes and the ones used for growing plants are a bit different from the regular ones in electronics. For agricultural purposes these diodes are placed more closely and this makes them more powerful thereby making their lighting capabilities a little more powerful. Throughout this guide you will be given all the necessary information concerning the LED grow lights.

The common bulbs produce a vast array of wavelength of light which in turn combine to form the white light we observe. On the other hand the LEDs make it possible for producing single wavelengths. The increase of power is facilitated by combining all the different light emitting diodes and the intensity can be adjusted while making it possible to change the color.

There have been several studies which have been carried out to determine the effect of the light from the sun. It has come to be known that the sun, although beneficial to the plants, it produces some wavelengths which can hinder the development of chlorophyll. This necessitated the need for developing a source which does not pose those effects to plants. This made the diodes a better option.

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.

The minute levels of heat emission experience by the use of diodes make it a good fit for agriculture. This allows the diodes to be strategically fixed near the plants so as to help the plants take advantage of proximity of all wavelengths. This helps facilitate plant growth and it is possible only because diodes do not use produce a lot of heat as a result of low energy consumption.

These diodes also eliminate the need for massive water quantities to be set aside for agriculture. Conventional bubs would cause significant increases in the atmospheric temperature within a space. This will make the plants lose considerable amounts of water as a result of excessive transpiration. The height of the plants is easily determinable due to all the sensitivity that most plants possess towards the proximity of certain wave lengths.

With diodes there is no need for a ballast to be incorporated within the system. These ballasts are often placed in other growing technologies with the view of preventing the system from destroying itself. Apart from being bulky, it uses a significant amount of energy to sustain operation. When such a unit is excluded using diodes, the cost of energy can be reduced to sustainable levels.

The adjustment of brightness produced by the diodes is necessary for the effective control of the wavelengths that the plants are subjected to. An interesting discovery linked to this property is that the anti-oxidation elements in plants are greatly fostered. All different brands of agricultural grade LEDs are very different from each other. Several properties are used to classify them and hence determine their suitability. The first factor is cooling abilities, followed by all the level of power consumption. The spectrum provided by a brand is also of great importance.
