I guess ill just buy a 600w mh hood and hang it from two shower curtain poles in bathtub.. I need a large enough light space to cover the plants as I have to start flowering some

Can someone please suggest a better way to veg these plants before they are ready to be flowered so that they get enough lighting? Im looking for a cfl alternative maybe that doesn't require a ballast. It is lesss $ to find something u dont need a ballast for.. In any case I may just pay $200 and stop wasting my valuable time asking for suggestion.
