Subject: What type of light is best for the different stages of growth in plants?

I am growing vegetables and flowers and I am wondering if I can 
grow them off the same light and what type of light I should use 
in the different stages of growth.  For instance, should I stay 
with a light that gives off more blue light when it is first 
growing and then change to a red when it is about to flower?  
Right now I am using a soft white floresent bulb that uses 25 
watts (100 watts normal bulb).  Do you think this is 
sufficient?  I wasn't sure if this bulb would give off the range 
of colors I would need.  Thank you in advance for your help in 
this matter.
