Growing plants indoors can extend your growing season, especially if you live in a cold-weather climate that makes gardening outside next to impossible in the winter. You will want to get a grow light system in order to provide your plants with enough and appropriate light. If you choose HID, or high intensity discharge lights, you've made a great choice because the bulbs most closely imitate natural sunlight and they last a long time. In order to use these types of grow lights, you will need some type of ballasts. A ballast is used to control the flow of currency through the bulb. If you choose digital ballasts for your grow lamps, they will last longer.



There are different types of ballasts available. An electrical ballast is used to limit the current flowing into a circuit. One of its benefits is that it helps the bulb operate at a higher efficiency. Electrical ballasts also come with an instant start, rapid start, and programmed start. Some use more energy than others, and some offer more reliable starts that others depending on which you might select.

Digital ballasts offer several advantages that other types of ballasts do not. One is that they weigh less than other types, an important consideration when you are hanging several lights above your plants. Another is that they run silently and have a greater efficiency than other ballasts, both of which save you aggravation and money. Digital versions of ballasts have start up times that are quicker than other types of ballasts, and they come in compact designs, so you can fit more lighting into a smaller space.

These digital ballasts also allow the lamps to put out more light than with other ballasts. It will save you a lot of money over time to use a digital ballast that allows the grow bulb to put out twenty to thirty percent more light, yet will run on the same amount of electricity.

Digitals ballasts are also safer than other models. Digitals come with circuitry that cuts off in dangerous situations. They also produce less heat, thereby increasing the safety. Digital ballasts can be used with metal halide lamps or with HPS, or high pressure sodium, lights.

Metal halide lamps give off blue light, and this is what you need if you are trying to get your plants to send up new growth. High pressure sodium lights produce light in the red end of the spectrum, which is useful if you are trying to get the plants to flower or produce fruits. No matter what type of light your plants require, there is a digital ballast that will both meet your needs and extend the life of your grow light bulbs.
