Im thinking about using some Cfl's for Veg and A 250 HPS for flowering for my indicas. I Need to know what I can do for a grow room setup that is low cost.

And What do I screw the Cfls in once I get them?? What Kind of Fixture.

You can buy a lamp socket at Lowes for $2 or $3, depending on the quality and hardware you need. Then just use any old lamp cord and you're good to grow.
