Indirect sunlight refers to light that is not shining directly on an object or surface, but rather is reflected or diffused. In the context of plants, indirect sunlight is often preferred over direct sunlight, as it is less intense and can help prevent sunburn and other damage. Indirect sunlight can come from a variety of sources, such as light that is filtered through a sheer curtain or reflected off a nearby wall. It is important to note that the amount of indirect sunlight a plant needs can vary depending on the species, so it is important to research the specific needs of each plant.
