If CFL (or LED) was the way to go we'd all be using it already. A cliche because it's so true.
Try adding the Gavita Pro 300 LEP (Light Emitting Plasma) if you got some money to spend and want full spectrum.
I am interested in the Gavita as well. I was really impressed with Sannie's youtube grow of shackzilla using the Gavita 1000 watt.
It is a 3 minute youtube of pictures from each week from seed til harvest.
