Effect of fine mist on growth and yield of tomato

Recently, a CO2 generator and an extremely fine mist generator in greenhouses have been developed, however, it is not clear how use of these machines affect the plant growth and crop yield. In this project, we analyzed how extremely fine mist affect plant growth and yield of tomato using temperature and vapor-pressure-deficit intelligent controller. It was shown that plant growth and yield increased because of promotion of photosynthesis using these machines during winter time.
