amount of watts

what is the perfect amount of cfl watts for 2 plants? and how many bulbs?

I grow 1plant in a 2x4x7 grow tent & I have 6 300watt equivalent compact floros. 2700k.
Get as many as you can. Or just read the lumens on the packaging. Get as many lens as you can. & make sure your using 6500k bulbs for vegg. & 2700k for flowering.
