When should I expect buds/spikes on my Cym

[RosieC]

I'm afraid my Cym is a NoID but it was flowering in December last year. Just wondering, assuming it will flower in December again when I would expect to see buds?

Also, it's outside now and temps are dropping into the high 30's. Would you usually see buds before moving it in (it will be going into a greenhouse kept at 40min) and how cold dare I let it go?

Will moving it into the slightly warmer greenhouse hinder flowering. Do these things need to go colder to trigger blooming?

So many questions which would be easier if it's wasn't a NoID Here's last years pics incase that helps.
