Auto vent opener
You can improve the performance of the ventillation in your greenhouse by adding autovents. These handy devices open vents automatically and don't require batteries, working from heat alone. Also, they tend to allow the vent to open more than a conventional manual opener, equaling better ventilation.

The MK7 Auto-window opener was a little tricky to fit but as is the nature when it comes to anything to do with greenhouses but what a fantastic product. I was a little wary at first even though I had seen them working on an allotment neighbour's plot - but rathrr would it work on my kinda wonky 2nd hand greenhouse and it is doing fine working perfectly helping me have mornings without havibg to rush to the allotment to open the window vent. Thanks Greenhouse People! And to Tim my allotment neighbour for introducing me to you!

Excellent, fast service from Greenhouse People, as always. (I've been dealing with them for years.) The vent opener is fine, but I found the easiest way to work out how to install it, is to study the Bayliss YouTube film. Installation then becomes very straightforward.
