Rust-resistant aluminum withstands outdoor conditions, providing reliable service season after season.
Designed for simple mounting with included spring wire and lock channel. Follow our guide or consult the manufacturer's instructions for best results.
To determine how many intake shutters you need, match the total intake area to your exhaust fan's CFM rating. As a rule, the intake area should be at least twice the exhaust port area. Place shutters on the opposite end or side from your exhaust fan to ensure even cross-ventilation. For exact sizing, see our greenhouse ventilation article.

As a general rule, the total intake area should be at least twice the area of your exhaust fan opening. For example, a 12" fan (approx. 113 sq inches) would need at least 226 sq inches of intake, which may require multiple shutters. Refer to the product's sizing guide or contact our support for specific advice.
Choose a shutter size that is proportional to your exhaust fan and greenhouse volume. Measure your exhaust fan's diameter and calculate the area. Ensure your intake shutters provide at least double that area. See our greenhouse ventilation article for detailed guidance.
Place intake shutters on the opposite side or end of the greenhouse from your exhaust fan to promote cross-ventilation. This ensures fresh air passes through the entire growing area. Position them low to allow cool air to enter while hot air exhausts from above.
Installation is straightforward: cut an opening to fit the shutter, insert the shutter, and secure using the spring wire and lock channel. For a step-by-step guide, search for 'Bootstrap Farmer aluminum intake shutter installation' or consult the included instructions.

Installed this on my greenhouse last weekend. Took about 20 minutes. Moves a lot of air and seems sturdy. Happy with the price too.
Good passive vent. My greenhouse temps are more stable now. Would have liked if the mounting screws were included, but not a big deal.
It does the job, but the shutter is a bit flimsy. The louvers rattle in wind. For the regular price, not impressed, but on sale it's okay.
This is exactly what my greenhouse needed. The aluminum construction feels durable, and it was simple to mount. I'm already thinking about getting a second one to improve cross-ventilation.
Works as described. The airflow is noticeable when the wind picks up. Installation was straightforward. Only issue is the louvers are a bit noisy in high winds.
I ordered this vent to help keep my greenhouse from overheating. It works perfectly. The shutter opens easily with the breeze and closes when it's calm. Highly recommend.
The shutter arrived with a couple of bent louvers. I straightened them, but it's not as seamless as I hoped. Also, the handle is a bit flimsy. For the sale price it's okay, but not impressed.
I was skeptical because of the price, but it's actually well-made. Very sturdy and the installation was a breeze. My plants are much happier with the extra airflow.
