yes you can i have just shut the light of for at least 24 hrs to beable to set the on and off time you want.Whats going on everyone,
Lets say the temperatures were getting to high during the day when you have your lights on. (12/12) .
Its been 3 weeks in bloom, can I switch them to turn on at night instead of the day..
Will that do any harm to the plants ?
Thanks
ah but great minds thinkalike. LOLI'd go 24 hours of darkness and switch after that. That should reverse your periods.
EDIT: WTG mygirls, beat me to it!
