This opener was awesome! I didn’t quite understand how it worked but it closed at night as the temp dropped and opened in the morning after the sun heated up. It was great not having to monitor myself.

You have a problem of poor packaging for this product. I would not recommend this product to no one. No installation hardware included in the box. Found a broken bag of loose hardware in the first delivery. Hope this opener works after all the back and forth with customer service.

I didn’t have it six months before it started to fall apart. I ended up taking the panels out and using the frame to grow roses on it because the quality was so bad.

High quality unit and east to install on two units but the other two units arrived defective and want to return them but the website makes it impossible to do so. Not very happy. I will buy from another retailer going forward.

Missing parts. Damaged parts, horrible instructions. Dealing with the manufacturer is disorganized at best. I’ve had the greenhouse over a month and I still don’t have all the pieces. Polycarbonate is as thin as my patience!

Palram - Canopia Greenhouse Automatic Roof Vent Opener for Most Canopia Greenhouses

ByCanopia

About This Product

The Automatic Vent Opener was designed to automatically control the temperature in most Palram-Canopia greenhouses. As the air inside the greenhouse warms, the vent gradually opens to allow the correct amount of airflow into the greenhouse and closes when the optimal temperature is reached. The vent arm was designed with the use of natural wax that expands to push a piston, which raises the window, as the air gets warmer then contracts as it cools, closing with the use of a spring. The Automatic Vent Opener operates without the use of electricity.

Features

  • Opens roof vent window automatically around 55°F for air circulation, closes when temperature cools
  • Durable metal design with natural wax
  • Smart-Lock connectors make installation quick and easy
  • Compatible with Hybrid, Mythos, Harmony, Snap & Grow, Balance, Octave, Essence, Chalet, Americana, Oasis, Glory, and Bella.
