Light hours and distance.

[vinchud]

Hi, I was hoping you could clear this up for me as i am confused on the distance and timing of the lights and the reasons why.
For example sometimes you advise peeps to move lights away and cut light hours down?
Or the opposite sometimes.
Thanks

Dark growth means more light needed. More light can be had by more hours, more LEDs/bulbs, or moving it closer.

White or bright yellow rubbery growth means the opposite.
