Bro theres a horomone that builds up in your plants when the lights are on but I'm too fucking stoned to remember the name of it right now. Anyways when any amount of light touches the plants (any amount) the horomone level drops and the plants then revert back to vegitative growth and therefore must build those horomone levels back up all over again. So treat your plants like Gizmo from gremlins and no light at all.

Ahh....Bright Light Bright Light!!!
