Why would you do that?

I have not done the experiment, yet light cycling on & off is called "pulsing".
There is a plant signal inter-action called "systemic acquired acclimation" (SAA) keyed to the light intensity.
A plant essentially gets adapted to a light intensity & then an intensity change can alter it's response. The SAA signal cascade reaches from the leaf all the way to the flowers' stems.
Pulsing might induce this SAA signal & fluctuations done in bursts (theoretically) will turn on & off all kinds of genes with favorable impact.
Hydrogen peroxide (H2O2) is one of the SAA signalers.
(So proponents of foliar spraying H2O2 may have another mechanism to explain some of their beliefs. Not subject of this post.)

Thanks, gringojay for the keyword "pulsing". I was able to find quite a number of links, some look quite academic, which was the sort of thing I was after.

Hi albert,
Let us know your conclusion.
