Low light plants should be kept away from bright light such as south-facing windows; too much light may scorch or even sun-burn their leaves. Even low light plants also need a certain period of darkness throughout the day to survive; ensure at least 8 hours of darkness each day for indoor low-light plants.
Select a location for your low light plant that's bright enough to comfortably read a book without having to turn on an extra light. Northern exposures, a place a few feet away from an east-facing window, or a placement away from windows in the interior of a room are your best options for achieving this. Stay away from southern exposures that may place your low light plant in direct sunlight.
Move your low light plant to the new location. If it's been living in a high light location, you should move it gradually from the high light to low light over the course of several weeks. This helps keep from shocking the plant, which might cause it to drop leaves.
Water your low light plant regularly just as you would any other plant. Most plants will do well if watered when their soil is just starting to dry out beneath the surface, although you should research each species of plant you have to make sure they don't have special needs.
Monitor your low light plant for signs that it might need new living conditions. Long, leggy stems and spindly or pale leaves may indicate that your plant needs more light; a profusion of small, densely packed leaves may indicate that it needs less light. Light brown spots on the leaves may indicate that your plant is being exposed to hot air, such as from a heating register, and needs to be moved to a cooler environment. Limp black leaves may indicate that it's being damaged by a cold draft such as from a window or a door.
