Cooling Solutions for Greenhouses: Protecting Your Plants

Greenhouses allow gardeners and growers to extend growing seasons, protect sensitive plants, and create ideal microclimates. But in hot climates—especially in places like Arizona—greenhouses can easily become too hot for plants to survive. That’s where the right cooling solutions for greenhouses come into play.

At Affordacool, we offer efficient, cost-effective cooling systems designed to regulate greenhouse temperatures and keep your plants healthy year-round.

Cooling Solutions for Greenhouses – What to Know When Optimizing Greenhouse Climate

Why Greenhouses Overheat

By design, greenhouses trap solar radiation to create a warm, humid environment. But during hot days, especially in summer, this process can lead to dangerously high internal temperatures, causing:

• Wilting

• Slowed growth

• Burned foliage

• Reduced yield or plant death

To avoid this, temperature control is essential.

Top Cooling Solutions for Greenhouses

1. Evaporative Cooling Systems

Evaporative coolers are ideal for greenhouses because they reduce heat while increasing humidity—both of which benefit plant growth. As air passes through water-saturated pads, it cools before entering the greenhouse.

Benefits include:

• Energy efficiency

• Improved humidity control

• Easy integration with existing systems

Affordacool’s portable evaporative coolers are perfect for small to mid-sized greenhouses needing mobile flexibility.

2. Ventilation and Air Circulation

Proper airflow is critical to prevent heat buildup. Combine roof vents, louvered side vents, and oscillating fans to move hot air out and bring cooler air in.

Pro tip: Pairing passive ventilation with an evaporative cooler creates a more balanced system.

3. Shade Cloth and UV Protection

Reducing the amount of direct sunlight through shade cloth or UV-filtering panels can drop interior temps by several degrees. This is a great supplemental measure in especially hot zones.

Choosing the Right System

The best cooling solution depends on your greenhouse size, plant type, and local climate. In the desert Southwest, a combination of evaporative cooling and ventilation often works best.
