    After constructing the Greenhouse yesterday, my son set out to installing the auto opener to control temps within the greenhouse. This will save me steps to running out and opening and closing the roof vent.

    Comments about : Automatic Vent Opener:

    Like that I don't have to keep track of the temperature inside the greenhouse every day. It's overbuild (will lift a 30lb window) for the aluminum, lightweight frame Harmony greenhouse (2lbs). Although it appears to be made of quality hardware. Needed to figure out how to attach as instructions were not for this greenhouse setup but figured it out OK. Simpler design might be cheaper to make and ultimately purchase.

      Comments about : Automatic Vent Opener:

      I tried a cheaper brand, but after returning them 3 times and still not working I decided to try this one.

      I was amazed. While this is not the cheapest on the market, here's one time when you truly get what you pay for.

        My little greenhouse is almost old enough to vote and the original vent opener finally wore out after faithful years of letting the heat out day after day. If I worked as well or as hard as that thing did I've have wore out long before it did!

          • Works On My Greenhouse

          Comments about : Automatic Vent Opener:

          This vent opener is for my 20 year old Northern Lights greenhouse. My husband had to make a slight modification on the hardware to allow the window to open. I would not have known to do that. This product is the only one out there I have found that works. The cylinder is the key to the workings, and it usually lasts several seasons.

              -As other people said the instructions are confusing, but once it is installed it's great. -Provides peace of mind, you KNOW that the frame is open when it's warm.

                  I bought a greenhouse from GS ten years ago and have needed replacement window openers for several years. This is a perfect replacement. I now just need to buy the thermo-piston parts for my other windows.

                  Comments about : Automatic Vent Opener:

                  The cylinder must be removed in areas with cold winters, or it becomes inoperable. Unfortunately I neglected to do this, all the cylinders failed, and now I'm looking to replace them. Otherwise these are very handy on the greenhouse to regulate the temp without having to be around.

                    I couldn't believe that it really works. I don't know how it actually opens the lid of the cold frame but it does. The lid is a little heavy also, so I was really surprised.It's easy to use and set up.
