Loaded question lol How do you want to grow..hmm your new grower so less is more. Me in my aero I grow 28 plants under 2 600 watters in an 8 x8x 10 room and I grow 16 plants in dirt in a 8x8x10 room under 1 600 watter.If your new you may want to go soil first couple rounds learn the basics.Id go 8-10 plants under a 600 watt light or even 6-8 under a 400 watter to get your feet wet
