As the world moves forward into the summer season, temperatures will continue rising. While the purpose of greenhouses is to keep plants warm, overheating can bring about an array of problems. Increased susceptibility to insects, higher risk of disease, reduced yields and lower crop quality are just a few of the issues extreme temperatures can cause.
In regions where the summertime temperatures are especially high, it is critical to maintain greenhouse temperatures at the desirable level, as few crops prosper in excessively hot temperatures. Over the years, several methods have been developed to keep greenhouses cooler, such as evaporative cooling, but greenhouse design has also evolved to more effectively incorporate passive ventilation. Ideally, growers will use a combination of passive and active ventilation to create the optimal growing environment. A balanced approach that uses both passive and active ventilation can keep both temperatures and costs down.
Reduce cooling costs with passive ventilation
The primary benefit of passive ventilation is its relatively low cost. The initial investment is lower when compared to active systems, and once your structure is outfitted with the necessary features, the utility and maintenance costs are low as well.
