Although some seeds definitely need light to germinate and therefore should not be covered with soil at planting (and some definitely need darkness), most should be lightly coveredwith soil as this will help the seed become moist as part of the germination process. When starting seeds indoors, plant the seeds and then place the container in a bright location but away from direct sunlight. The reason for this is that not only does a certain amount of light penetrate the soil, but also because direct sunlight could raise the soil temperature excessively. Once the seeds begin to germinate, then be sure to place the container in the brightest light available. Many home gardeners do find that supplemental lighting is necessary to produce the best quality seedlings.
