The use of LED rests on this scientific fact: when it comes to light received by plants during growth, color is more essential than intensity. Natural light is composed of the colors ROYGBIV – red, orange, yellow, green, blue, indigo, and violet. Growing plants benefit from all these colors through the photosynthetic process. Based on scientific research, the “blue” part in the light spectrum encourages vegetative plant growth, while “red” is perfect for stimulating flowering or fruiting.
Thus, LED lights were invented for plants to get blue and red lights necessary for their growth. Even without sunlight, plants can have light sources through LEDs. According to researchers as well as plant growers, LED lights are great sources for artificial lighting. However, caution should be exercised as the heat emitted by these lights can damage plants. LEDs should be placed at least 12 inches away from the plants being cultivated.
The use of a LED plant light for plant growth has many benefits. Compared to other plant lights, LED is energy-efficient. LED lights can last for up to 50, 000 hours. A regular light bulb, on the other hand, can only last for 170 hours. LED lights also need less power in producing light. A three-watt powered LED generates energy outputs similar to that of an incandescent bulb that has 45 watts.
Unlike high intensity discharge or HIDs, LEDs do not need ballast in order to operate. LEDs have built-in fans as well as systems for heat removal. When looking for a LED light, you may want to consider those that have their own ventilation fans for extra cooling.
LED lamps are made from biodegradable materials. These do not contain harmful elements, such as lead or mercury. LED lamps are more environmentally-friendly compared to light bulbs and other light sources. Also, these are safer and can be disposed in landfills.
Although LEDs may be costly compared to other light sources, these are a great investment. Because LED plant lights come in different types, choosing the best one to suit your purpose may be quite challenging, but the trick is to choose a LED plant light designed for the plant you are cultivating.
