The plant in that pic....

THe loewer stems went completley bare....lost all foilage. ONce I started flower, all leaves down there dropped off because of no light....

The canopy top was so big almost no light got to the lower braches.

The light you see there made it all grow back.

I used a $26.00 CFL from fullspectrumsolutions.com and have a fan blowing right on that bulb....

It is a 55W 5500K.....

I wouldnt use anymore....

I tried it with my 125W CFL and baked an entire stem worth of bud....even with the fan on it. Too much foilage to cleanly circualte.
