No issue with what you want to do. I recommend leaving lights off for 24 hours, as opposed to leaving lights on for 24 hours. Doing this once in a while will not hurt your photo period as far as the plants are concerned. It takes more than 1 day for plants to realize that you flowered them.
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
