So - a cold north-east wind last night?

 - and the larger greenhouse has 2 sides? - one faces north?

And who forgot to close all the manual vents on that side? And that after misreading the forecast & failing to open them in time to deal with the sudden afternoon heat!! = Tim

Oh Tim you sound just like me - I didn't check the weather yesterday and certainly didn't expect all that rain. And I had just spent two hours scooping water out of my daughter's paddling pool with a watering can and distributing it around the garden. Hope all survived in the greenhouse!
