How to Fit and Adjust an Automatic Greenhouse Vent Opener
You know you have to keep your greenhouse warm when it is cold outside but did you know that it is also important to keep it cool enough on those hot summer days so that your crops are not heat damaged?
Damping down, utilizing blinds, screens or shading paint can help to keep your greenhouse cool. It is essential that there is consistently adequate air circulation in your greenhouse.
If you go away in the summer months it may be a good idea to install an automatic vent opener in your greenhouse. The vent opener contains a mineral wax. When the temperature gets too high the wax expands opening the vent and when it cools down the wax constricts and the vent closes.
When purchasing your automatic vent opener it is a good idea to check the weight of the roof vent on your greenhouse. Some roof vents require a stronger vent opener than others to keep them closed, this is especially true with the lightweight vents on UPVC greenhouses.
What are automatic greenhouse window openers?
Automatic window openers work similarly to vent openers. They rely on a wax that expands when heated to move a piston in a tube which in turn opens the window. An environment-friendly window opener is great for any passionate gardener as it means you can be away from your greenhouse and not worry about your plants getting heat damaged.
Installing the AutoVent
You can find automatic vent openers at any garden center or online. They are fairly simple to install, all you need is a few minutes, a greenhouse, the automatic ventilation kit, and a screwdriver.
Here is how do it:
Step 1: Holes
Ignore all holes on the greenhouse bars, all the autovents we supply use simple clamps that clamp to the Aluminium greenhouse frame, the top bracket goes onto the window, the lower bracket goes onto the frame slam bar. If using on a wooden frame simply screw through into the wood.
Step 2: Adjusting
You may have to adjust the amount your window is able to open by rotating the main tube of the automatic window opener. If necessary.
Step 3: Test
Wait for a hot and sunny day to see if your automatic vent opener is working properly.
