Ventilation is absolutely essential in tomato production because it controls the climate in the greenhouse and affects both plant growth, yield and quality. Tomatoes require stable conditions with proper temperature, humidity, and CO₂ levels to thrive. Without ventilation, the air can quickly become stagnant, temperatures rise too high, and humidity become too high, increasing the risk of diseases such as gray mold and mildew. Effective ventilation ensures fresh air, helps regulate temperature and humidity, promotes photosynthesis through the supply of CO₂, and creates air circulation, which strengthens stems and reduces pest infestation. In short, ventilation is essential for healthy plants, high yield and consistent quality in tomato production.
