Greenhouse Ventilation System

Ventilation is the single most important requirement for a greenhouse. Without ventilation, your greenhouse becomes a solar furnace and creates an unhealthy environment for your plants. Ventilation not only provides fresh air for your plants, but it also helps cool your greenhouse to combat harsh external weather conditions. Proper ventilation helps cool the temperature of your greenhouse, particularly during the summer months, extending your growing season and increasing production and yield.

While greenhouses allow plenty of sunlight inside, there is very little air movement creating a stagnant environment. Ventilation systems help reduce humidity and temperature and lessen the risk of plant disease. An efficient and reliable ventilation system works to remove hot air while continuously introducing fresh, clean air. Good ventilation systems also help plants replenish the carbon dioxide and oxygen expelled during photosynthesis, ensuring healthy growth.

Natural ventilation systems are ideal for small greenhouses and greenhouses of all sizes that are located in areas of mild climate. These systems rely on wind and thermal buoyancy for air movement. Cooler air enters the greenhouse through vents placed on the side walls. As the air heats up, it rises and exits the greenhouse through roof vents, creating a cooler growing environment.

Larger greenhouses and greenhouses located in hotter, more humid climates benefit from mechanical ventilation systems. Mechanical ventilation systems create air movement with the use of fans, which bring fresh air in while exhausting unwanted heat and humidity. These systems can be automated to keep your greenhouse environment consistent regardless of the conditions outdoors, giving you a higher level of control over your growing environment.
