LED Grow Lights- The Future of Indoor Plant Growth

Ever since the indoor cultivation of plants took a boom, high-pressure sodium lights have always been the choice. But now, the advancement of technology has given rise to a new player- the Light Emitting Diodes.

LED grow lights were invented long before but their popularity has recently surged. A huge number of indoor growers are picking up on LEDs for their indoor cultivation and are showing stunning results. The market now has a good number of very high quality LED grow lights available.

LEDs took a start with being red only, as they were used in TVs for producing the indicator lights showing that the device was ON. LED technology has since progressed a great deal and is now capable of producing colors encompassing the entire light spectrum. New growers may have questions regarding the viability of Led grow lights-through this article we are trying to provide insight into the future of indoor cultivation through LEDs.

What Are Light Emitting Diodes?

These Light Emitting Diodes pass current through a semiconductor material which results in movement of electrons, thus causing production of light. There is no loss of energy in the form of heat, making LED grow lights up to 4 times more efficient than conventional bulbs.

LED vs. HID In Indoor Cultivation of Plants

LEDs took a slow start as HID was previously dominant in the marketplace-but the rigorous developments and work on LEDs has lead to some convincing results. Once you enter the market, you will have numerous brands offering their special grow lights. One grow light technology that catches our attention is Dorm Grow G8LED grow light technology.

The G8LED has high quality infrared diodes that output a nearly invisible wavelength beyond the light spectrum. G8LEDs save 60% on electrical consumption and give off very little heat, even at the 50,000 hour of lifetime. These lights introduce the ideal color ratio of 8 bands of the color spectrum for a great yield, 100 natural result, and investment that pays off quickly.

Power Consumption- LEDs produce light in a very efficient way and are known as “luminous efficient”. LED was shown to have an efficiency of 150+ lumens per watt, comparatively; a standard HPS lamp has shown an efficiency of 100 lumens per watt. Thus, LED will save 50-60% on electrical consumption.

Lifespan- LED has a longer bulb life, lasting between 50,000 to 60,000 while HID bulbs last for 2,000 to 3,000 hours.

Heat- Since LED does not burn filament, their heat signature is much smaller than other lighting sources. LED has the advantage and feasibility of being able to be closer to the plants without burning them.  Furthermore, the reduced heat output results in better room temperature control and reduced requirement for air conditioning, resulting in further operational savings.

On the other hand, a HID bulb wastes 95% of its electricity consumption as heat and radiation. HID bulbs must be placed high above the plant to avoid burning. Although this can be an advantage in colder regions of the world, it is in most cases an added nuisance to the grow room.

Light Intensity- In the past the LED lights were not able to produce large amount of light intensity, but now LED grow lights have shown production of enough intensity to match the yields from HID bulbs. One of these latest technologies that have proven to be able to do this is the G8LED grow light system with its Optimal 8 bands design.

Color Spectrums- LED now covers all the light spectrums required for healthy and natural indoor plant growth. For example, for the growth of cannabis, blue and red lights form the main required light spectrum. You will have some high end systems featuring a mixture of blue and red diodes to fulfill such requirements while in some you can adjust it.

LEDs take a step ahead of HID grow lights, as they can produce the maximum peak spectral output of a specific color. Thus, high quality LEDs output a better quality of light than a HID light. This result is better photosynthetic production of plant growth and fruiting/flowering yield.

Cost- High quality LED grow-lights pay for themselves just in operational savings. The typical return on investment period of high quality LED grow lights is 10-14 months, depending on the cost of electricity in the region.  Add to this the reduced need for air conditioning and the elimination of hardware such as magnetic ballasts, hoods, reflectors and changing of bulbs and you will see that LED grow lights are not only a cheaper way to grow indoors but the inevitable technology that will dominate the marketplace.
