A. BACKGROUND OF THE STUDY
In previous years, the numbers of family that live in subdivisions have been increasing. Where, these subdivisions provide small lot area for planting. The families living in this kind of houses may have decided to plant indoors or stop planting. These families that have resulted to plant indoors may have had difficulties in their plants. One of these difficulties may be the source of light.
Besides water and mineral nutrients, plants need sunlight in order to make chlorophyll. Aunice Reed defined sunlight as the most essential need of every plant. It enables plants to make food. Plants need sunlight in order to survive and grow strong and healthy. Not only do plants supply the earth with the oxygen we need to live, but they also serve as food for the entire world, and that includes the animals, too.
Plant flowering is greatly affected by photoperiodism. According to Muller (1974), photoperiodism is the influence of light exposure of different duration of plant growth and development. Some plants that are exposed to short dark period grow longer but have few flowers. On the other hand, the plants exposed to short light period grow shorter but have more flowers.
Intensity also affects the growth of plants. The brighter the light, the greater the energy the plant receives. To determine how much light a plant will require, consider where and how it grows best in its environment.
