Artificial lights can be a simple fluorescent lamp set at the correct distance away from the plant. You may also purchase special grow lights from garden supply shops. Using artificial orchid lights, you can mimic the natural cycle that the orchid receives in its natural setting. In addition to fluorescents and incandescents, metal halides and high pressure sodium lights are available in the market. Plants benefit from these orchid lights by the blue or red colors they emit. Blue makes your orchids grow while red encourage them to bloom. It is a good idea to mix up the colors so that the orchid can benefit from the light variation.
