Exhale CO2 bags work through photosynthesis – photosynthesis is the process by which plant leaves make carbohydrates. Sunlight, CO2 and water are converted into carbohydrates and O2 by the action of chlorophyll in the chloroplasts of the plant. Plants growing indoors under artificial light often lack enough CO2 to efficiently photo-synthesise. When plants are able to maximize the process of photosynthesis, the result is larger plants with larger yields.
