LIGHT: African violets are grown indoors. They like bright, but filtered, sunlight. Do not place in direct sun. They can also be grown under florescent lights. The lights are usually suspended 12 to 18 inches above the violet for 8 to 14 hours a day.
Give a plant too much sun and it will look bleached, pale, or event burned; too few hours and it will have thin leaves and elongated shoots. Some plants require about a half day of light, while others need up to 18 hours of light each day; the latter include vegetables, which will get pale without sufficient light. Still others, such as African violets, need only about eight hours of light per day year-round. Many indoor plants might get a few hours of direct sun each day, but the angle at which the sun hits a window can be undependable. And natural light isn't strong or long enough to grow herbs or vegetables indoors.
