Keeping cool in the greenhouse






In hot weather like this the horticulture staff is trying to stay cool. Greenhouse crops can also suffer from heat stress. The greenhouse is equipped with a pad and fan cooling system to mitigate the heat in the greenhouse. Pad and fan cooling is an evaporative cooling process. Fans on one end of the greenhouse pull the greenhouse air outside while on the opposite end of the greenhouse, water pours through the pads. Air coming into the greenhouse through these wet pads evaporates the water in the pads and cools the greenhouse. Other circulating fans and vents in the top of the greenhouse called ridge vents are also used to cool the greenhouse.


In this hot weather the greenhouse staff will try to stay cool by caring for ourselves, as well as the plants.
