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!
