I'm pretty new to growing but am attempting to build a dual chamber grow box to fit in my closet. One box for clones/mother and another for flowering. The flowering box I have in mind would be roughly 4 ft. tall x 4ft. wide x 2ft. deep. If I'm looking to grow 3 plants roughly 2 1/2 ft. tall this should be enough space right? Any suggestions on light arrangements? I was thinking a 400w HPS for the flowering but I'm not sure if that is too much or not enough. Another concern of mine is the beautiful aroma of my plants drifting into police nostrils. Any advise on odor control? I have heard mixed things about how strongly flowering plants will smell and since I have never grown before I dont know what to expect.
