    I have remived mine every year and am late getting them out this year but then I wondered, is it really necessary?

    Anyone got an opinion about this or had experience with leaving them over a cold winter?

        I don't see the point in removing them, Lori:dunno: It's very unlikely they'll open when it's cold and even opening (doubtful) on a warmish Winters day it wouldn't do any harm. I've never had maintainance problems with them by leaving them in place.:coffee:

          Thank you @ARMANDII and @Mike Allen. It is a bit of a pain to take them out every year and that's probably why I procrastinated.

              Always leave mine in place.
              Depending on type you could just unscrew the expansion tube and wire down the vent if you think there is any chance of strong winds opening the vent.

                @pete I keep the manual openers in place as a back up in case of high winds on a warm day. I was worried that the cylinders might get damaged because one year, a cylinder leaked out and stupid me didn't know that I could possibly just order the cylinder and not the whole unit. I threw the whole unit out :doh:The cylinders are still rather pricey even just on their own so I was trying to avoid another leaky unit. Actually, I never did find out what caused the one to fail :scratch:

                    I've replaced the cylinders on mine I've got 4 Bayliss vent openers, not sure you can get them over there @CanadianLori , I've had them for more than 15 yrs so I'm not complaining about leaky cylinders, nothing last for ever;):smile:
                    But I dont think its because I've left them in situ over the winter, I kind of think the heat in summer is more likely to damage the seals.
                    But then, that is what they are there for. :biggrin:

                      Are manual openers ones that only open once a year? :lunapic 130165696578242 5:

                        @shiney my manuals would be annuals if it weren't for windy days... :)

                        One of the greenhouses is playing storage shed and buttery at the moment. I'm stockpiling butter for my Christmas baking and it is the ideal temperature out there to park them. 12 pounds so far.

                        oh, and forgot to mention that the one Shineybrid that I brought inside to try to overwinter, is doing poorly. I think I'll just harvest it's peppers and start new after Christmas. :)

                            Hmmm, maybe I'll bring mine upstairs and place him near a window too. I think we one more hour of daylight than you do at this time of year. Our shortest day will be 8:57 hours on the 20/21st. Thanks for letting me know @shiney as I didn't want to give up!

                              Our kitchen is usually about 70F but windowsill will be colder at night and warmer in the day with the sun shining on it. :blue thumb:
