My greenhouse came without an automatic vent and so am on the lookout to buy one.

I have been on the link below but if anyone could advise which they think is the best buy and more importantly simple to fit (hubby not brill at DIY)

The B&Q one is fine , simple to fit but it`s a swine to get the little pin in the hole.
Remember to remove the cylinder overwinter or the frost will kill it.
It`s the only one i`ve used so there may be better about.

I can't remember what make we bought but it was about £15 from ebay.  What a fabulous buy it was too!!!!
