an electromagnetic spectrum stroboscopic photon source adapted to be positioned proximate to said members of the Plantae and Protista Kingdoms, said stroboscopic photon source producing a plurality of micro-doses of intense pulsed light in random or synchronized sequences, each micro-dose having an exposure time from about 0.01 milliseconds to about 10 milliseconds within an electromagnetic spectrum range from about 50 nm to about 2200 nm;

wherein each micro-dose comprises a pulse cycle comprising an energy trigger pulse, a flash in which instantaneous PPF is reached, and a decay period where PPF returns to zero;

wherein the energy trigger pulse initiates ionization of inert gas within said stroboscopic photon source with a trigger pulse width of 10 μsec to 350 μsec for a strobe light with an input of 3 to 400 watts and an output of 450 to 8,500 watts in peak radiant flux, which includes light produced in the visible and electromagnetic spectrum (Red, Far-Red, IR, Green, Blue, UVA, UVB);

wherein said decay period comprises two to seven times the length of the flash period; and

wherein said stroboscopic photon source has a peak performance peak-to-time average ratio of between 50-8000 for a 30-watt strobe assembly, where the peak-to-time average ratio is the ratio between the photosynthetic photo flux density (PPFD) over the span of a second and the peak PPFD measured instantaneously.
