Alright i think that i am about ready to start my new batch but first i gotta order my seeds! I know that i'm wanting to grow white widow, northern lights, and white rhino! how many do you guys think i can grow using my equipment? I'm using Farm Farm soil and nutes, a Digital Greenhouse 600 Watt Ballast with HPS and MH Bulbs with a reflector and Mylar on the walls and floors. i'm not sure what size the room is yet, i havent measured it yet but i'd say 10' by 12'! I am going to flower at 24" and flower for i'm thinkin 75 days! The only thing that i am not sure yet is if i'm going to use C02! I might but i really dont understand the ins and outs of it so idk about that! Any suggestions on either topic would be appreciated!

If the room is 10x12, you will want more light, or partition off the room. A 600w should be good for about 6x6 with good reflection. if you are going to veg to 2 feet, stick to 5x5 or about 6-8 plants i would think.
