All mine go out into a walk in pvc greenhouse during the day and back indoors at night.
I have left about 8 spare sweetcorn and 1 courgette out there the past few nights and they're fine ... but some really cold weather forecast still to come in the next
couple of weeks, so they'll
get whipped in at night with the rest if needs be.
44mph winds being forecast here over the next week or 2!!!! ... then again, thats according to metcheck
