I am 4.5 weeks into flower indoors. The strain I am growing need cooler temps to to finish nicely and prevent mold in the dense flowers. I usually have them lights on through the night 9 pm 9 am during the summer months. This makes it easier for me to keep the temp lower. I hadn't worked out timing for the warmer weather we've been having here now. My question is, is there a safe method to gradually change there timing from am to pm lights on? I don't want to shock them or make them turn hermi, so I'm a bit nervous. I had a power outage the other day and used that to push timing forward 3 hours. So I have lights on from 12pm -12am atm. Would it be safe to remove an hour or 2 of light per day in their morning, until I have them at 8pm -8am? Or????
