All types of plants need light to survive. Houseplants are no exception, but they might not receive all the light they need indoors. Providing additional electric lighting for houseplants can give them the light they need while they grace your home with their beauty. A mixture of plant fluorescent and cool white fluorescent lights is a good balance for lighting indoor plants, according to the University of Missouri.
Determine what kind of lighting your houseplants need. Low-light plants need between 50 and 250 foot candles which are provided by a single 40-watt fluorescent tube. Medium-light plants need 250 to 1,000 foot candles which can be provided by two 40-watt fluorescent tubes. High-light plants need 1,000 foot candles, or more, which can be provided by three or four 40-watt fluorescent tubes.
Place the fluorescent tubes into the lighting fixture. Use one plant fluorescent tube for every cool white fluorescent tube.
Plug the lighting fixture into the wall and place it above the plants you need to light.
Position the plant below the lighting fixture. Space low light plants about 1 to 2 feet from fluorescent tubes. Space medium light plants 6 inches from two fluorescent tubes. Space high light plants 6 inches from four fluorescent tubes.
