I flipped my lights on July 1st. My power has been out for a day. It usually goes on at midnight and off at lunch. My light has been off for over 24 hrs a full day. Other than that plants are healthy
Good luck finding a generator now; plants can survive awhile without light. They will stress out though when lights go back on. I’m in the dark too btw, power co says 3-5 days to restore. 5 years ago we lost power for 10 days; plants recovered but were severely stressed.
