PRODUCT OVERVIEW

Model # 701338

Internet # 202075434

The Automatic Vent Opener was designed to automatically control the temperature, humidity and provide additional ventilation when needed, making gardening easier. As the air inside the greenhouse warms, the vent gradually opens to allow the correct amount of air flow into the greenhouse and closes when the optimal temperature is reached. The vent arm was designed with a metal cylinder containing wax which expands when heated 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 and resetting the piston. All you need to do is to install it on your roof vent window and it automatically starts working. The Automatic Vent Opener operates without the use of electricity and works with all our Greenhouse models only.

CUSTOMER REVIEWS

Rated 4.6 out of 5 by 13 reviewers.
Rated 5.0 out of 5.0 by Works great Easy to install and works great. One thing I have just noticed is that if you put a heater in the greenhouse the vent arm will open if it gets above 65 inside. We'll see if 30 degrees outside what happens. So it is really responsive to temperatures. November 11, 2014
Rated 5.0 out of 5.0 by Just what I wanted! Wanted a hobby greenhouse to keep the rodents from eating all my veggies. If you take the time to sort all the parts so you can find them before you begin, the greenhouse goes up quite easily, although it takes a good 8 hours with 2 people for this particular kit. It is very substantial when together and I just love it. Stays quite warm inside even on chilly nights. The shed is great for all my tools. Couldn't be happier. May 7, 2014
Rated 5.0 out of 5.0 by Best Purchase Ever This product is absolutely wonderful. I would highly recommend it to anyone, it works perfectly. I don't have the hassle of opening and closing the vent daily or being concerned about the temperature of the greenhouse if I am away from home. October 29, 2014
Rated 5.0 out of 5.0 by A handy accessory! I recently purchased the 8’x8’ Snap and Grow greenhouse and purchased this at the same time. I am so glad that I did! The temperature in my area fluctuates pretty often and I am a little too short to reach the standard arm that came with the greenhouse, so this was just what I needed. September 28, 2010
Rated 5.0 out of 5.0 by What a time saver! We purchased 2 of these hinges for our new greenhouse. Installing them was easy, and when put in place, they actually open up on their own. Amazing invention. This will save us some headaches, as we won't have to worry about our roof vents in the greenhouse not getting opened. I am happy we purchased this item, even though I thought they were a bit expensive. But if this invention saves my plants from burning up, then it was worth every penny we spent on them.
