How to build a greenhouse roof vent.

This is part 2 of the greenhouse where i show you how to build the doors and the vents for the greenhouse. Vents in the roof or wall of a greenhouse usually do a good job at passively allowing hot air to escape. Natural ventilation or curtain ventilation uses a series of roof and sidewall vents. You can fill in the gaps of the framework with wood except for the roof.

As the temperature increases within the greenhouse hot air also rises and escapes through the roof vents. Placing two vents on two opposite sides of a greenhouse ensures cross circulation. All of which work to some degree and continue to be used to this day but it is hardly is cost effective. This creates a vacuum that draws cooler air into the greenhouse through the sidewall vents located closer to the ground.

Ventilation for greenhouse roof. 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. When you pair that with opening the main door it creates a nice cross breeze that will draw fresh air through the greenhouse. Ideally you want to have cross ventilation so two windows on two sides of the greenhouse work best.

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. Natural ventilation for a greenhouse or any translucent roof solar structure has always been the ventilation method of choice. Greenhouse roof vents work really well as they are located where hot air gathers naturally at the peak of the roof. This step by step woodworking project is about 8 8 greenhouse roof door and vents plans.

Light must get in transparent plastic or cheap glass. As opposed to forced air by way of mechanical fans air intake louvers circulating fans. If vents in the roof are not possible make sure to at least have a window to two you can open. And last here is a simple greenhouse design with a sloped roof that allows water to fall on the ground.

Use a fan that is encased a waterproof housing with an air.
