Sorry to wake up an old thread but I wanted to just ask about supplemental lighting in the flowering stage to up the number of lumens psf I'm currently going to be around the 3000 lumens psf mark using 2700k CFL's. If I was to add additional CFL's to my setup to increase the amount of light, should I just add more 2700k bulbs when flowering or is it beneficial to use 5600k bulbs as well. Which would be most effective?
