General Lighting Requirements For Plants

To determine how much light a plant will require, consider where and how it grows best in its natural environment. Most vegetables, for instance, grow best in full sunlight, which means as much light as possible must be supplied to grow vegetables indoors. Foliage plants like the Philodendron grow in full shade and therefore can grow normally with relatively little artificial light. Exotic plants, such as Bromeliads, grow in varying conditions depending on the species. Some grow in deep shade in the jungle, while others grow in bright sunlight. The lighting level required for growth indoors depends upon the characteristics of the particular plant being grown.

Color Temperature

In scientific terms, Kelvin temperature is  expressed in degrees Kelvin (°K).
In simpler terms, it is the degree of warmth or coolness of a light source, not with regards to the physical temperature, rather to the visual temperature of the light. The higher the degree K, the more blue, or "cooler" the lamp appears. The lower the degree K, the more "warm", or red the light.
