Hydroponics gardening makes a great hobby anytime of year, but especially during those dark cold winter months. In this system of indoor gardening, plants are grown without using soil. Instead, they are grown in a growing medium, feeding off of nutrient solution. As with any type of indoor gardening method, hydroponics gardening requires the use of grow lights in order for the plants to be able to synthesize food, grow, and reproduce, producing flowers or fruit. HID lights are often used for this purpose. HID, or high-intensity discharge lights, come in several varieties, including metal halide grow lights and HPS grow lights. All HID lights require a digital ballast in order to control electrical current through the lamp and ensure its proper function. Most also benefit from being used in conjunction with a reflector, which will direct and intensify the light that the bulb produces. LED grow lights are also very popular. These lightweight lights, using light- emitting diodes, produce a lot of light in colors useful for plant growth, and are cost effective as well. All of these lamps make great grow lights for hydroponics.Metal halide grow lights consist of an arc tube made of alumina, inside of which
