Not really... I mean yea it helps. But really, for CFL growing.. any growing. When it comes to lights, the red spectrum is for stem growth as well.
One thing all CFL growers must remember.
When putting CFL lights up for growing?
For veg, you want more Blue Spectrum
or "daylight" = 6500k.
But for Flowering, you should be using MIX SPECTRUM LIGHTING!!!! It should be a mix! of blue and "soft warm" spectrums!
Just my 2cents.
