I live in the West of Scotland. Up here it's rare that you have more than the odd day in summer when temperatures get dangerously high in the polytunnel. But this year we're being blasted with wall to wall sunshine and high temps day after day. I rarely get the tunnel below 30 degrees during the day, and even with shadecloth, regular hosing down with cold water and a fan blowing fresh air through the door I'm still creeping up to 40 degrees C regularly thoughout the day. All doors and vents are of course wide open.
The tunnel is positioned so that it is in full shade from around 4 oclock onwards, and partial shade from around 2pm. It's 3pm now and despite all my efforts it's reading 39 degrees.
Everything looks fine still - tomatoes, peppers, melons, cucumbers.
Would appreciate advice from those in warmer climates.
