lights on/off per 24 hours??

I agree, 16 hours on, 8 hours off.

So many things in nature key in on the length of daylight to do certain things in relation to the time of year. At our latitude here, our longest days of summer in late June have about 16 hours of daylight and 8 hours of dark. So, by giving my seedlings 16 hours of light I'm 'fooling' them in March and April to 'think' it's already June - that they're running behind schedule, and must do extra well to catch up.

That's my theory anyway, and whether it's right or not I raise some real nice seedlings by following it.
