Grow Lights Guide

By Susan Slobac

If you are starting out with indoor gardening, there is a lot to learn. One of the important environmental factors that you will need to provide for your plants is appropriate light. Plants need light for photosynthesis. Plants have the amazing ability to change light energy through photosynthesis into glucose and oxygen, which they need to thrive and grow. You will want to consider the grow lights you use in your indoor growing area very carefully, because it is a major aspect that will affect the success of your gardening venture. There are several new grow lights, and very popular ones include HID lights, HPS grow lights, LED grow lights, and MH grow lights. These are all hydroponic gardening grow lights, and all can be used with plants grown in soil as well.

HID lights go by the full name of high-intensity discharge lights. MH grow lights and HPS grow lights are also high-intensity discharge lamps. HID lights produce a great deal of light that more closely resembles sunlight than the light produced by either incandescent or fluorescent light bulbs, which is better for plant growth and reproduction. The way light is produced by HID lamps is when you turn the electricity on, the current runs through a ballast, which regulates the electrical flow to the electrodes, which are inside an arc tube, along with various gases and metals. When an electrical arc is produced, the gas in the tube helps start the light bulb, and the metals, once they reach the appropriate temperature, evaporate and produce the light that you see.

HPS grow lights make excellent hydroponic lights. HPS stands for high-pressure sodium, and these are used by professional growers to produce vegetables and flowers indoors commercially. HPS lamps use mercury in the arc tube, as well as sodium, and this makes for good color rendering, or colors showing up accurately when lit by the bulb. The spectrum color that a bulb gives off is important, because plants thrive under different colors depending on their stage of maturity. If you are trying to grow lettuce, for example, you will want to use the blue light spectrum under which it thrives. If you have mature tomato plants that you want to produce fruit and flowers, then you will want to use a red/orange spectrum to induce the plant to behave appropriately.

LED grow lights are called this due to a light-emitting diode that allows the lamp to produce light. These lights are handy because they come in an array of colors used in growing plants, and they produce a lot of light that is easily focused where you need it. They have a very long life as well.

MH grow lights are metal halide lamps. The arc tubes of these compact and efficient bulbs contain argon gas, mercury and a mix of metal halides. Like other HID lights, these lights require the use of a ballast in order to function properly.
