Is this one of the reasons why in ebb&flow some don't flood during lights out, but do so right before lights out?

It might help, but more likely you'd experience plant droop during the dark phase, which then makes the plant take longer to take off at lights on.

I can not address ebb & flow systems but know in aero that it should run durring lights out, it is a time when the plants uptake most of their water/nutes.

Granny Storm Crow recently posted on a thread about plant stretch, passed on a reference to some university that found adding alcohol to the water mix caused a plant to stay short but produced flowers equal to a regular plant.

The better way is to use a far red source just before lights on and again at lights off. I better describe it on another thread. I'll see what I can do to find it and maybe link it (I'm not computer literate) or you can seach here for it.
