This research is a study of the effectiveness of the mechanical, hydroponic and software components of a biowall that improves indoor air quality through plant assisted phytoremediation. The research investigates the ability of the device to sustain plant health in a controlled environment over an extended period. This is because, the biowall has intermittent airflow through it. This airflow, has a detrimental effect on the health of the plants in the biowall. After studying the horticultural and mechanical aspects needed to operate a biowall, appropriate control algorithms were developed. These algorithms controlled the biowall’s lights, irrigation, and fan.
