Warmer weather is coming! Is your greenhouse prepared? Call us today toll-free at 1-80 to talk with one of our representatives or visit our website at to get your plants and your greenhouse ready to take the heat! Some of the benefits of this option include: preventing plants from drying out or wilting, like some vented systems operating costs are lower than fan-and-pad cooling achieving nearly 100 percent cooling efficiency and allowing wet bulb temperatures to be obtained. This low-cost solution, when used with fine nozzles, can introduce additional humidity in the greenhouse, and that moisture can help reduce the frequency of watering plants. Misting or Fogging: These systems use high pressure water delivery to emit very fine water particles, and the drops evaporate in the air, reducing the temperature. Evaporative cooling systems are ideal for drier climates, but can provide cooling anywhere in the U.S. Pads mounted on a sidewall are supplied with water, and air drawn through the pads by fans on an opposite wall can drop the indoor temperature by 10 to 20 degrees below what’s outside. Evaporative cooling systems like these use the heat in the air to evaporate water from plants and other wetted surfaces to lower the greenhouse temperature. Take care that light is not reduced to undesirable levels, such as on cloudy days or early mornings or near nightfall when light is not as intense.Įvaporative Coolers: Fan-and-pad systems are the most common for summer cooling. Shading can help make other types of cooling systems more efficient by reducing the sun’s intensity, as well as retain heat overnight. External blinds are the most effective, but keep in mind they may obstruct efficient vent operation. Internal or external blinds can also help. Shade paints are a quick way to filter the sun’s strength and can be applied in more layers in higher heat and washed and brushed off during cooler spells. Shading: Paints, blinds or cloths are another low-energy cooling option for your greenhouse. A system that combines exhaust fans with vents helps increase the efficiency of excess heat removal, but may still need to be used in conjunction with another cooling method. Using natural ventilation alone will not bring the indoor temperature lower than the outdoor temperature.

Though vents carry lower operational costs, construction costs may be higher. Vent positions can be changed manually or mechanically to naturally maximize benefits from wind direction. Vents: Traditionally, vents placed in the roof have allowed the warmer air that rises to escape, while drawing in cooler air from side vents. To lower the temperature in your greenhouse, consider the following cooling systems and the benefits that they offer. Regardless of where you are, plants in an overheated greenhouse will experience a loss of stem strength, reduction of flower size and a delay of flowering. Of course, your challenges are going to vary depending on your local climate, but cooling a greenhouse will require a combination of shade, ventilation and humidity that works in your particular growing zone. Helping your greenhouse keep its cool is going to be paramount for your plant health and growing success in the warmer-and sometimes downright hot!-days of summer.
