My outside cabinet grow is ready to go into 12/12. I would rather have the lights on during the day, which would keep the closet at 75 degrees +/- 5. The night time low is around 45, and hardly ever gets in the thirties. Would the night time temps harm my plants in any way? My understanding is that as long as it does not reach freezing, my plants should be ok during no light period (night). Is this correct?
PS: I live 35 miles NE of San Francisco.
