Go Green With LED Grow Lights


The choice for many customers looking to purchase natural, healthy vegetables often comes down to how much more organic produce costs compared to regular produce. Mass produced farming techniques can be harmful on the environment, dumping tons of pesticides and fertilizers into the soil system, but organic produce that does not use toxins can be as much as twice as expensive. Luckily, there is another choice available: using indoor gardening to grow your own food on a year round basis. Growing your own fruits and vegetables is not only extremely inexpensive and fun but can be done with almost no environmental foot print. The key to your own selection of produce, however, lies in how you provide valuable light to your growing plants. LED grow lights have been proven to grow larger, healthier plants over the duration of a single growth span.

The current source found in a normal house is called incandescent lighting and is powered by a basic electrical surge creating friction within a light bulb. This light is appropriate for illumination and can power the elementary photosynthesis needed by all plant cells. A light bulb, however, does not provide the valuable vitamin D of sunlight that plants (and humans) need. The choice for indoor growers, thus, comes down to the choice between high-intensity discharge light (known as HID) and light-emitting diodes, also known as an LED light. The difference between the two lies in the power source and the amount of energy needed to fuel your plants’ growth.

An HID light does not produce illumination by friction, as a bulb will. Instead, two conductors are placed apart from one another and a surge is ran through. The gases inside the bulb accelerate the process, while metal salts literally melt into a plasma that will emit radiation in the form of light. Harmful radiation is contained while the light powers a plant’s photosynthesis. HID lights are most often used for large-scale illumination, such as nighttime sporting events, which require significantly more power. Individual units put out less heat than a normal bulb, but in large arrays require significant cooling.

LED grow lights do not have the raw power to light up a stadium, but make up in efficiency what they lack in overall strength. An LED lighting array may consume only a quarter of the electricity than an HID system will, while they produce almost no heat. This keeps your plants from being burned, dehydrated, or withering from oppressive bulbs! Unlike a HID system, that needs fans and reflection units, LED grow lights do not require further purchases. An LED array can run for as much as ten years without interruption, which is ten times longer than an HID outlet.

By utilizing LED grow lights, anyone can grow their own produce year round. With these efficient, simple, and inexpensive arrays, any quantity or quality of fruits and vegetables can be grown for consumption or sale. While a grower has to make difficult choices with regards to soil, water, pH, and nutrients, the decision to use LED grow lights is a snap by comparison.

Growing A Future With LEDs

In the world of indoor gardens, botanists have always been restricted to using high-energy lighting, but recent advances in LED grow lights can save huge amounts of money on energy bills. LEDs, or light emitting diodes, have been around for quite some time for use in computers, flashlights, and even the headlights on a car. In fact, since the 1980’s NASA has been attempting to produce and perfect LEDs for use in greenhouses and recently these technological advances have made their way to the consumer market allowing all growers to replace expensive, inefficient greenhouse lighting with LED grow lights.

There are actually several ways LED lighting can save money beginning with electricity. The standard metal halide or high-pressure sodium light typically costs approximately $35 per day to run assuming a 600-watt bulb. Obviously, costs will vary by area, but overall this is an exceptionally expensive light to run for any extended period of time and many people simply do not have the money for a greenhouse based on this cost alone. The primary issue with these lights is they are extremely inefficient since only 35% of the electricity input actually is converted into light, and all the other energy is converted into heat. For the consumer, this means that not only is the bulb costing money on the electricity used, but also on cooling the building during the summer months to maintain the proper climate for the plants.

Today LED grow lights only consume between 2% and 50% of the electricity used by other forms of lighting and in fact, some use such a small amount of electricity they can even be run using small solar panels placed outside. Fortunately, the savings are not just evident in the electricity, but also in the heat. LEDs emit very low levels of heat so more of the electricity being put into the bulb is actually being used to produce light. Yet, the advantages just keep coming; LEDs used in grow light arrays are engineered to put out only a very specific spectrum of light. Since plants can only use a small portion of the electromagnetic spectrum this means no light is wasted on wavelengths the plants cannot process.

LED grow lights may be more expensive as an initial purchase, but over a relatively short length of time will begin saving amateur and expert botanists alike huge amounts of money. With bulbs expected to last as long as 15 years combined with all the electrical benefits the cost of using these lights is expected to be roughly half that of conventional lighting. As this technology advances, greenhouses are sure to continue to reap the benefits and even greater savings.
