Love the setting.
I have had to deal with night time temps like that the whole summer (9-11C 48-51F) That alone wont hurt as its only that temp a coupe of hours. Your plant is mature, its pretty tough BUT if you can take it inside at night you will sleep better. :)
Good luck
Looking great!! I grew in an outdoor tent once (covered patio) in early spring and it was a constant MacGyver fest for southern California with cool temps and high humidity.
