    Hi guys, when I've put my greenhouse together where is the best place to put the louvre vent??? On the side of the greenhouse (east/west) or the opposite end to the door(north) any advice would be most welcome :help:

      Think I would opt for low down on the opposite end to the door.
      I'd tend to only use it during summer, although I've never had any louvers, they always look like really draughty features even when closed, to me.:smile:

        Thank you for your view on the louvre question. I thought it made more sense to place it opposite the door too

            Would it make any difference which side the louvre went. Down here in South Wales the majority of the winds come from a South west direction. or has wind got nothing to do with it???

              I had to have my greenhouse east to west due to layout of garden and away from trees. Placing your louver vent opposite the door gives an even flow. wind has nothing to do with placement/

                Thank you for helping out with my question Alex, I was just unsure where to place it as this is my first venture into gardening/greenhouse ownership. I'm trying to get things right before I start.

                      Surely venting louvres should be high up , to remove damp warm air . And if you have the choice , rarely possible, on the leeward side of the prevailing wind :scratch:

                        My thinking was, I have 2 roof vents (1 east, 1 west) the door is facing south so surely it would make sense to place the louvre vent on the rear.( north) That way all four sides will provide ventilation??? Or is that not the case??

                        Did you say this is a 6x8? Two vents and a louvre in such a small area, placement really doesn't mean much. Making sure strong wunds doesn't rip them out should be more of a concern in MHO..

                          Yes Lori it's 6x 8 but everything I've read said it's more difficult to get ventilation in a smaller greenhouse?? Unless I've mis-read the information. That's why I paid extra for louvre vents. I hope I didn't pay extra for something that I really didn't need!!! Oh well I've got it, it can be used in an emergency if we get a really hot summer lol:tomato:

                            @Spacemunkey I don't think you can ever have too much ventilation :)

                            I just wouldn't be worried about not having enough with what you now have. Good air flow over here is mostly desirable up and out- in the summer as we get super heated summers and trying vent the hot air fast enough is a challenge. I find my fans have stopped any worry about circulating the air too and so far :fingers crossed: have not had any issues with mould or mildew.

                            Sounds like with your louvre vents, you'll have great success. :)

                              I would agree with that. As most know, hot air rises. Therefore, a louvre vent placed high on the opposite wall to the door would tend to draw air through the greenhouse and naturally eject it.
