It just dpends on how much light you have. Yeah 24hrs of weak light and they will still want more, but crank that light up and they might not like it so much.
I agree....I have heard people refer to this as light saturation

If using low wattage lights (such as CFL), then 24-0 works perfectly fine...especially if your environment goes cold during lights out

If using high wattage lights (such as HPS) then 24-0 can over saturate the plants, as such a 16-8, 18-6 or 20-4 may be better
