When do you put your Orchids outside in the UK

[RosieC]

I didn't have a test subject for Saturdays outing, but one of them had been out in full autum sun during the daytimes last year I found it needed that to start flowering.

They were all cheap NOIDs though so I'm not too worried about them... although they are all growing nicely just now.

I think my more expensive Den Startdust will stay in, it's also not a Den phal type so not sure what conditions it will like.
