Just trying to decide which way to go for indoor growing. I have a room that's about 8' X 12' which is an extra bedroom, question is.. do I want to build a grow cabinet inside this room OR just use the entire room as the grow room. I'm leaning towards putting a big table in the room, then use CFL's, ventilation really isn't a problem. A fan and open window fixes that. Trouble is, with such an "open" area, just how effective will the CFL's be and should I go up in size?
