So what is your point? I advised to keep lights off in order to change time off day.

And; If you want to change over your lights on/off schedule you err on the side of darkness; As I said.
bitemybud Reviewed by bitemybud on . can you alter the dark and light hours? I have a perpetual grow going but my veg room has out paced my one to three plants into flower a week pace. I also just want to finish out this strain. So I am going to flip my veg room to flower to so both rooms are on same time on and off so I dont have to mess with light leaks from one room to the other either. My flower room is light tight but my veg isnt. Now onto my question. Can I alter what hours are the dark hours in my flower room? I.E. I'm on a 9am to 9 pm lights on cycle but Rating: 5
