okay, for 10 plants, a 600 watt hps would work and a 600 watt MH for vegging if you can afford it, you can use hps all the way if you want, of course you need pots, and maybe fluorescent tubes and those tray things for sprouting... then there's the medium, foxfarm ocean forest works well with perlite (optional but worth it). ventilation, probably windows in that room... some fans.
