I donāt recommend ever spraying plants. If you feel the need, do so only immediately after the dark period starts and only one time per week for the first three weeks of flower.
exactly or if the tent is in a bright room you can turn off real bright lights for an hour. I run LED strips in my tent for aux lighting and just leaves those on if I have to spray or I splash the leaves @CannabisLover89
@CannabisLover89 Thats a good light cycle for autoās from what I understand. I havent done any of those yet. Plan to this winter. But I am sure @bob31 will chime in here on it. Better than me for sure.
From what I read people keep it on for the entire grow @CannabisLover89. They believe it maximizes yield. Iāve never grown autos but that sounds logical since they will flower no matter what.
I have used a variety of different light schedules. I havenāt noticed any real difference. The last two grows I ran 12/12 and grew two great blueberry autos @CannabisLover89
