Good light for your indoor house plants is as important for your house plant's health as is proper watering for indoor house plants. You have some control over elements of your tropical houseplants care, including adequate light, proper temperatures, relative humidity and, to some extent, air quality. Keep in mind that watering for your house plants is directly related to light, temperature and other environmental conditions.
It would be wonderful to be able to keep and maintain your indoor tropical plants in a well lit greenhouse where you have control over the light your potted plants receive. It is easy to provide the correct light in a greenhouse for optimal growth. Most of us do not have this option and have to make use of artificial light or make the best of our homes natural light.
Good light is essential for a plant's health. Photosynthesis cannot take place without a certain amount of light. Lower light means slower growth, less water and a reduced need for nutrients. When placed in a situation where the light is less than optimal, your indoor plants will not thrive, becoming thinner over time.
If you have large windows, skylights or a sunroom, it will be much easier to keep your house plants in a good light situation. However, when keeping tropical plants inside your home, it is often not possible to give them the optimal light that they need. If a compromise must be made, most plants will adapt to lower light situations though they will not be as full, lush and healthy in the long term with reduced light levels.
There are three elements to consider regarding the light that your houseplants receive. These are the light quality, the duration of the light and the intensity of the light. Without the proper amount of light, indoor houseplants can not thrive and grow.
Light quality refers to the light waves coming from the light source. The sun will provide the full spectrum of light waves that plants require and for that reason is preferable to artificial light sources. Artificial light can be used and the most often used substitute for natural light is fluorescent lighting or special full spectrum lights.
The duration of light is just as it sounds, the number of hours of light a plant receives per day. The day length, or photo period, regulates photosynthesis and other plant functions. Generally, the hours of light per day, or light duration, should be somewhere between 8 to 16 hours for most indoor houseplants.
The light intensity is its brightness and is often measured in foot-candles. If you have a light meter you can measure this and if not, it may be helpful to know that the average indoor light intensity can vary from 15-500 foot-candles. Most house plants are going to do okay somewhere between 75 and 250 foot-candles. Flowering house plants are generally going to need to be at the higher end of that range.

Placing your indoor plants as close to a natural source of light as possible without exposing them to hot, direct sunlight is preferable. If necessary, you can group them together near a window, under a skylight or in a sunroom out of any direct hot sunlight.
Many office buildings have fluorescent lighting only and most tropical indoor plants can be maintained under artificial light for quite some time. There are other types of artificial light and the cost of those types of light sources has become quite affordable. Natural light from the sun is a great way to help insure that your houseplants are healthy and thriving but supplement with artificial light if needed.
Indoor plants vary in the amount of light they require. Plants that grow more slowly tend to tolerate lower levels of light. The more light a plant receives, the faster it grows and water and nutrient usage increase accordingly. While most house plants do quite well without any direct sun, placing them close to a good, natural or artificial light source will be quite beneficial for them.
