Default Optimum light period for planted and non-planted tanks..?

You have to ask the tough question don't you.
optimum time frame for a planted tank can vary depending on the plants used.

I have had tanks that do very well with only 4 hours of artificial light
(2-3 wpg), and I have had tanks that required 12 hours

Also I have had a tank that had no artificial light, it was in a south
facing baywindow, exposed to direct sunlight (just a tiny bit more than
4wpg ) for roughly 5 hours a day, shaded during the strongest period
by the hedge outside. That one required pruning every week.

Can you tell us what type of plants you are looking at, and then I am
sure someone can give you a better idea.

happen in both cases if the light period isn't regulated and just turned on
at different times each day?
