If you don't have space near windows, you can grow African violets successfully under artificial lights. Plants receiving 12 to 16 hours of light from double fluorescent bulbs will reward you with ample blossoms. If light levels are too high, the leaves will be small and yellow-green. The plant may or may not flower. These plant pets need to be moved to a more shaded location.
African violets are fussy about air and water temperatures.
Air temperatures from 60 to 80 F are preferred. Keep plant pets away from hot or cold drafts for best growth. If you are comfortable, it is most likely that your plant pets will be comfortable as well. Water temperature is also important. When watering African violets, the water should be at room temperature or slightly above.
