I turned it to 12/12 and the light is off during the day and on at night. Which one is best during the flowering period? Off at night, on during the day, off during the day and on at night?

I’m in socal where I have hot dry days (90° ) and cool humid nights (65°). I grow in a tent in the garage - so I prefer to have lights on at night so my high temperature is mitigated to 75,. If I were to run lights on during the day, my high temperature would be well over 90° in the tent, that’s not good. I use the same scheme in the winter as well, The nights are too cool so I run lights to warm up . The days are perfect 70° so I have lights off during the day. So think of your highs and lows and how your light will help you achieve a constant good environment in your grow room. Best of luck on your grow

Does not matter, the plants will not be able to tell the difference, but if your day temps are high, having the lights on during the night makes sense.

Todzilla makes great points. Also at night the electricity companies charge less for electricity during those hours. So you can save a bit of coin.
