If your CFL's are properly placed and you=r grow area is desinged right, you dont need the side lights during veg.

It is easy to manage to tops of the plants with CFL using a fan.

But with side lighting, remember the lights do get hot enuff to burn plants. And with fans blowing stems and leaves around....it can create more burn problems that wipe out any benefits.

Besides, side lights just arent needed with proper CFL's and reflective properties. Not during veg.
