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.
Vegetable seedlings need 14-18 hours of light a day. Botanists usually divide plants into three categories relating to their preferred day length: short-day, long-day or day-neutral. Short-day plants, such as chrysanthemums, kalanchoe, azaleas and begonias, will thrive on less than 12 hours of light per day. In fact, these plants must usually go through a series of even shorter days before they will set buds and flower. Long-day plants require at least 14 to 18 hours of light each day.
