Choosing CFL's

Hi there, i need to know what to go for when buying CFL lights. I have a few questions:

1. Would one red and one blue cfl at 125w do for a veg operation?
2. What are the differences between the colours?

Cheers

Ones red ones blue. lol. The blue spectrum lights are better for vegatative growth and early root development. The red is better for flowering. A lot of folks put some red in vegging and some blue in flowering. My hydro shop suggest a three to one ratio of red to blue spectrum for flowering. VV

Thanks man - Good advice.
