Overview

Make sure your greenhouse ventilation is constantly regulated during hot summer months, whether you're at home or not, by installing an automatic vent opener. Readily available, they're quick and easy to install, so heat-stressed plants will be a thing of the past.

How to do it

1Place the opener in the centre of a window vent and mark the position of the holes on the window frame and greenhouse frame.

2Screw the automatic window opener to the frame of the window then check that the window can open and close.

3If necessary, adjust the amount the window opens by rotating the main tube of the vent opener.

4On a sunny day, watch and wait to see that the vent is opening properly.

Adam's tip

Fit opening windows on the side of the greenhouse which faces away from prevailing winds.

UPVC greenhouses have lightweight roof vents and may require a stronger vent opener to keep them closed or prevent them being blown away.

This is a must if you are going to use your greenhouse to the full. Fitted my vents when I built the greenhouse 10 years ago and have only just had one fail last week, even with the high cost to buy they are well worth it.
