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.
The growing cycle is also controlled by light. This is one of the main advantages of growing marijuana indoors. Initially in the grow period (vegetative), lights are kept on for approximately 18 hours a day. When you want the plants to begin flowering the light is restricted to 12 hours light (and 12 hours dark).arijuana Lighting. All plants need light and there is no sun indoors. The light provided by the sun needs to be replaced with an artificial light source. Incandescent lights, like regular light bulbs, simply won't cut the mustard, they put out light in the wrong spectrum and are too costly to run.
