I live in Finland and so the seasonal daylight varies from almost none in winter to always in summer. I got a smart socket connected to my grow lamps for all my plants. I used to have an analogue timer that I would have to keep changing the times on as the season progressed. The smart one now turns on when my alarm goes off in the morning and turns off an hour after sunrise, turns on again an hour before sunset and turns off at bedtime.
No messing about anymore, it’s one less thing to worry about.
