I bought a 2x2 hydro farm silver grow tent. When asking a light recommendation for this space ( I plan on growing 4 plants at a time) a guy at the garden center ordered me 400 watt combo Mh and Hps. Is this too much for a small tent ? I know u guys probably hate answering dumb questions but please help I'm panicking. I realize I still need to get some fans and I definetly want a filter hooked up to the ducts for smell. Please any feed back would be appreciated
