Lighting Tips. Proper lighting duration is just as important as the light intensity. Tomatoes require at least eight hours of direct sunlight daily or 16 hours of artificial light per day. If you are growing seedlings indoors in spring when they don't receive eight hours of sunlight, you can supplement the natural sunlight with artificial light after sunset to equal 16 hours.
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.
