I was reading this thread: https://www.rollitup.org/grow-room-design-setup/655291-combating-summer-heat.html , on the first really hot day of the year, and was thinking about changing my lights so they're not on during the hottest part of the day. Given my current timer settings, I would have to move things back about ten hours. I suppose I'd have to do this in small steps rather than all at once, right? So, how much can I change the timer each day without messing up flowering?
