Phototropism is the natural inclination of plants to grow towards the light source. Plants will actually bend toward the window and thus need to be rotated or have supplemental artificial light placed so that the plant receives even light. Otherwise, the plant will have excessive growth on one side and little growth on the opposing side. Photoperiodism is the plant's innate response to its environment. Even indoors, plants perform best in a rhythmic cycle of light and darkness that closely resembles their original habitat.
Plants are absolutely dependent on light for their survival.
Therefore it is crucial to ascertain the light available at any given plant station prior to choosing the plant specimen. With the use of a hand held light meter, the foot-candle level of light may be ascertained, and the appropriate plant may be placed in the ideal light setting, resulting in a healthier, better looking specimen. Recommended Plants A lthough plants can adapt to various light levels, including low light, they will not flower or be at their optimum under such conditions. With insufficient light, plants live off their energy reserves, and gradually die. As their energy level expires, they become unable to absorb sufficient energy to regain health.
