For your tomatoes you can grow a stockier transplant with a daily 
brushing the tops of the plants. Check out this page at cornell, 
complete with videos on how to do it:


I don't have any experience with 250 watt systems, so I will leave that 
to someone else. 3x3 sounds reasonable for a new bulb, maybe iffy for an 
old bulb with no natural light. Be sure to use white "walls" on all 
sides to help bounce light back so the plants are not all leaning into 
the center.
