    Thanks again everyone, great advice on ventilation. We are in Lanarkshire so just outside of Glasgow but it's still quite chilly haha.

    Thanks for they links, I will check them out.

Up here in the frozen north one side is plenty I should have said with the windows/lights you need another base bar below.
    Would love to see a photo of your polytunnel!

    I only have one pic on my phone showing a side view on the non vented side, i.e. the side without the lights/hinged windows so that's not going to show much of interest. I may have other pics on an external hard drive. I'll rake that out and have a look

    another option I have heard about and is slightly more complicated is


    Fit a base rail and a side rail and cover with plastic as normal


    Cut a circular hole where you want ventilation.



    Stretch a section of scaffolding netting and a polythene between side and base rail and a poly cord down each side. Secure both netting and plastic and ends of cord each side at top. Secure netting and cord on base rail. Get a wider piece of doweling, secure bottom of plastic - Dowel in between cord and netting. Wind up plastic on dowel and use a clip to secure it a opening required.

    The cords prevent the dowel / cover flapping in the wind.

    I used 2 x 1" x 25mm bits of pipe with a slit along one edge as the clip.

    best luck
