new grower needing advice

dude, go here www.jonsplantfactory.com this is a canadian website, they have everything you need and they will ship to you,

lights, ballasts, tents, nutes, everything
don't complain about your crappy harvest if you only have 70w hps!!

if you do stick with cfls keep the plants small and you will produce better buds but that will be hard with an autoflower try growing 1 at a time till you get better lights.
