Placing two vents on two opposite sides of a greenhouse ensures cross circulation.

How to build a greenhouse roof vent.

When you pair that with opening the main door it creates a nice cross breeze that will draw fresh air through the greenhouse. Roof vents are also good as the hot air rises and the temperature in the greenhouse can be lowered in the summer simply by opening a vent. As opposed to forced air by way of mechanical fans air intake louvers circulating fans. Natural ventilation or curtain ventilation uses a series of roof and sidewall vents.

This step by step woodworking project is about 8 8 greenhouse roof door and vents plans. You can fill in the gaps of the framework with wood except for the roof. Natural ventilation for a greenhouse or any translucent roof solar structure has always been the ventilation method of choice. Light must get in transparent plastic or cheap glass.

This creates a vacuum that draws cooler air into the greenhouse through the sidewall vents located closer to the ground. Ideally you want to have cross ventilation so two windows on two sides of the greenhouse work best. And last here is a simple greenhouse design with a sloped roof that allows water to fall on the ground. You can also use fans to create additional air flow such as an exhaust fan.

The 3 windows are enough to ensure ventilation. Greenhouse roof vents work really well as they are located where hot air gathers naturally at the peak of the roof. As the temperature increases within the greenhouse hot air also rises and escapes through the roof vents. This greenhouse has two large doors for an easy access to the interior and four vents so you can cool down the air.

Use a fan that is encased a waterproof housing with an air. This is part 2 of the greenhouse where i show you how to build the doors and the vents for the greenhouse. Install a ventilation fan on the back wall of your greenhouse cutting a hole near the roof that is large enough for the fan to fit. Vents in the roof or wall of a greenhouse usually do a good job at passively allowing hot air to escape.
