I dont think it has a whole lot to do with lumens/sq.ft. myself...

I think what I should really be worried about is:
Total Watts/sq.ft.X Total spectrum/lumens of light source @ plants different life stages of growth..

And the Spectrumxlumens/sq.ftXlight source...

With that being said, Yes plants do use all light spectrums to grow obviously.With enuff light of any type i suppose u could grow a plant to smoke. But thru out a plants life span It grows and matures during the seasons of its environment. Whether next to the equator or not it all comes down to light being bent by the distance of the earth from the the sun that creates spectrums when it enters our atmosphere and distance from the sun also creates these seasons naturally.
Its been scientificaly proven that plants use mostly blue light spectrum (actinic ) to be exact,found in alot of m/h bulbs during early stages of life also found during seasons of spring and summer and fall. This spectrum is also found in hps and that cfl only tries to mimmick but works great if ur doing a stealth grow.
Its also been proven that during a plants latter stages of life adolescence, puberty and maturation.That a plant uses more Red light spectrum to mature and reproduce Which happens during fall and winter when the distance of the sun from the earth is greater.


Hope this helps peeps out making decissions when building a grow.


Stealth growers should be concerned with this as well:

Growth Production and Light emittence= Quality and Quantity+time
Time=money Devided by light eficiency and quantitiy.

Blue spectrum ( cfls m/h )= growth for veg
Red ( hps ) spectrum= Reproduction and maturation x quantity for flower
