Using the light readings, your home can be divided into four areas, which have the following light levels for 8 hours per day: For example, if the f/stop setting is f/16, the approximate light level is 2,400 ft-c.

Light is needed for plants to produce food and survive - generally, the more light available, the more food produced for growth. Of all of the factors affecting plant growth in interiors, adequate light is by far the most important.

Plant growth is affected by light, temperature, humidity, water, nutrition, and soil. To be a successful indoor gardener, you need to understand how the interior environment affects plant growth and how cultivation differs from growing plants outdoors. Many of these chemical compounds, which are released into our air through a process called вЂњoff-gassing,вЂќ come from everyday items present in our homes and offices. Indoor plants not only convert carbon dioxide to oxygen, but they also trap and absorb many pollutants. In addition, houseplants can be a satisfying hobby and can help purify the air in our homes. Interior plants are an ideal way to create attractive and restful settings while enhancing our sense of well being. We spend about 90 percent of our time indoors.
