In this study, we built a mock-up of an indoor garden for private use and vertical gardens were installed on the walls of this indoor garden model. The purpose of this study is to examine the types of plants for best fit for growth and nurture in vertical garden and to identify the effects of indoor air quality improvement by these plants. As the result of the experiment, 22 species out of 32 species previously used for indoor garden was selected to be suitable for vertical gardens of a personal indoor garden. 10 species were found to be inappropriate for a personal indoor garden in terms of ornamental value, growth status and maintenance. The effect of plants on reducing CO2 has been proven by many studies. Also, through photosynthesis, plants combine CO2 with water and produce sugars and O2 (oxygen). Everyone accepts this fact. In nature, the production of oxygen is so important that without plants we would soon use it up and die. From the NASA Fact Sheet we know that air contains 20.95% O2 and 0.04% CO2. If you had enough plants in a room to use up all of the all of CO2 and convert it to oxygen, the oxygen levels would increase from 20.95% to 21%. This increase is difficult to detect and would have no effect on humans.
