Are you closing up overnight?

Tunnels, I mean. My tunnel faces east and catches all the early morning sun, and by the time I get there to open it up, it's already extremely hot inside right now. If I shut the door but leave all the side vents open, do you think any of the tender stuff will get upset about the swing in temp?

My tunnel and greenhouse have not been closed since this hot weather begun. I have recorded 45 degrees in the greenhouse and this morning at 9am the tunnel was 35 degrees.

Same here

Tunnels, I mean.

Closed at night. It doesn't get the sun very first thing and both doors are fabric allowing air movement. We wouldn't want to make it even easier for the mice, now would we? 

I like the idea of a fabric door. But wot if the nighttime temp dips ...... Do you put the glass back?

Thanks. I've been getting temps well into the 40s in my tunnel every day since this hot spell began. Even with everything wide open all day, I can't get it down to a sensible level. Maybe if I leave everything open overnight it won't build up so much when the morning sun hits it. The peppers are loving it though, I've already got baby fruit on my chillis and sweet peppers, and all are new sowings this year.

I think everyone needs to close up, at least overnight - as the next few days are forecast to be cold 

Yeah id agree - reckon it will be clode to freezing here tonight. Hope all is well come the morning sun (rain!)

Car registered 12.5 just now. Forecast is 10 overnight
