Thank you for the video, last night my greenhouse dropped to low temperatures and it made me think that the vent didn't close all the way so I'm adjusting it up but it's nice to see exactly how it operates! :D

I am surprised it worked. If you read the instructions, you really want the body of the opener parellel with with window so the "clutch" mechanism doesn't break. Also the clip goes through the second hole in the clutch not the top hole. Plus that basil will not produce since it go exposed to that cold spell. It will become woody and perform poorly. Simply start over with fresh seed when the weather warms a bit. Good luck. Nice greenhouse.

Thanks for the video. I purchased a different opener and it didn't work for my cold frame. You set up is very similar to mine and I can see the style you installed will work for me too. It's hard to tell from a picture of the product how it will actually function. Now I can buy with confidence.

We just finished (well still in progress) our Greenhouse we made from old windows and doors. We are in Texas, so the temperature swings are pretty big. It was in the 40's this morning, but it was already 90' when I went out there. I need to add some of these to help it cool off on days when it warms up.

It's based on the same principle as the liquid dilatation sensor in sanitary hot water boilers to regulate the heat by controling the flame output. The fluid dilatation pressure is impressive.

I am loving the bloopers you’re putting in at the end....and great drone footage!

Yep, I bought the same from amazon. Worked perfectly for the first week. Then the thread between top of cylinder and the ring got worn out, so was not working any more. So I put longer screws to squeeze the cylinder top and prevent slipping. Yeah, it worked fine... for 2 more days! That's when the bottom of the cylinder popped out, so the unit can just be put in the garbage after less than 2 weeks. I just ordered another one NOT from amazon. btw the windows weights about 1 pound. Warranty? amazon don't give a dam.

Nice visit. The homestead is looking great.

Thanks for the info on the installation of the vent, just an FYI if it's 90 degrees out u might have a problem screwing the rod in.

Hi. So funny because I have 2 auto arm openers which are on my cold frames and this year I decided to get one for my hoop house. I opened YouTube to check some out and yours was the first one that came up! This year we bought a fan that is also triggered by heat and it runs on solar power - not sure if this is going to work but we'll see. We had the super cold snap, too fortunately my seedlings are still in the house because in Canada we can't trust the weather...yet. Not even with a hoop house :)

Any updates on your greenhouse? Getting ready to make one and wondering how long it will extend my growing season. Zone 5a. Love all your videos... thanks for sharing!

[dammit]

Would you be so kind to show how you actually installed the window and managed to keep it from leaking. I watched the videos of the window build but the actual instal is a little iffy.

[charlesdixon]

Thanks for the video. We purchased a used greenhouse and it has an auto vent opener. I wasnt sure how it worked but now i do. Im not sure if its working properly and i may need to purchase a new one.

What do you do if it's warm but raining and don't want the plants and stuff to get wet
