Jemp Vents

jsh99

Hi all,

As I've posted before I've moved into a property with a lovely big greenhouse and am new to this gardening malarky.

Apparently it has 'Jemp Vents' in it.

I've looked these up on the internet and found some information about them - how they open close automatically depending on the temp.

But what I can't find is how you set the temp at which they open???

Also one seems to be perminantly open - is it faulty? If so what's the likely problem? Any ideas?

Cheers!

I'm not sure if they're Jemp vents but I have automatic vents in my greenhouse. You adjust the temperature by turning a screw at the end furthest from the window. If one's permanently open it could just be that the screw's stuck.

Well I found the reason one is stuck open when I had a better look this morning - the grape vine is growing out of it!! No wonder it won't shut!

I'll ry turning the screw thing at the end then (after removing the vine) and see what happens!
