WSA,

The technical issue is that fluorescent lights do not have a continous spectrum, although they appear white to our eyes, but they emit only certain wavelengths.As a rough statement, chlorophyll absorbs blue and red light, so the illuminating light must have a decent output of blue and red portion of the spectrum. What type of plants you have?

This table might be helpful "Luminous efficiency of various light sources".

It also depends on what you are growing. If you are going for ariods like Epipremnum aureum (money plant), peace lily, aglaonema etc then a 45 watt energy saver installed not more than 6 inches above the plant will work..
