What Is Medium Light for Indoor Plants?


Plants need light to create food through the process of photosynthesis. A plant lacking proper light can grow spindly, shed leaves, and fail to produce flowers. Medium light refers to one of the three types of light requirements for indoor plants.


Measured in foot-candles (ft-c), light intensity indicates brightness of light. Medium-light intensity for indoor plants can range from 100 to 500 ft-c.


Duration signifies the number of hours of light that a plant receives in a 24-hour period. Most plants need exposure to at least 200 ft-c for 12 hours a day for best growth.


When it comes to light, quality refers to light color or wavelength. For plants to properly use light for energy, they need exposure to red and blue wavelengths.


As the sun travels through the sky, windows facing different directions of the house receive varying amounts of sunlight. Placing plants in eastern windows or several feet from western ones give adequate exposure to medium light.

Medium-Light House Plant

Some medium-light house plants include African violets, ferns, and dumb cane. Begonias, ficus, and Schefflera also grow well in medium light.
