This is not to say that CFLs don't produce. They do. I've got 2 plants under CFL, and am expecting about 2 oz+. If I had 300W of HPS in there I'd prolly be getting a qp+.

HPS & warm white CFL produce 2 different spectra. HPS about 2200K & CFL about 2700K. I think these 2 spectra mixed would produce amazing results. When I move next month, I plan on adding a 150W HPS to my 300W of CFL in the new grow room - not closet! Yay!
