For reference, the ideal time for the lights to be “on” during the day for vegetative growth is 18 hours of light for 6 hours of darkness. That is 5am to 10pm ! For flowering you want to move to 12 hours of light and 12 hours of darkness. Flowering and fruits is the same time.
Time:
Like space but more personal and precious, although you are free to use it as you wish, it will force you to travel in only one direction. It will be fair to all equally but some will get less than others. Sharing time with someone is the greatest gift you can receive.
