My plants are on week 5 of 12/12 light schedule. I just realized the extension cord going to my tent came loose from the socket it was plugged into. My lights should have come on 3.5 hours ago. My question is.........do I change my light schedule to ensure they receive 12 hours of light today or keep the schedule they have been on and deprive them of the 3.5 hours, or something in between?
