I always have 1 box fan and 1 oscilating(sp?) fan going in my room so I got the noise thing covered, If I could keep the smell to a minimum I think I could get by cause I smoke in my room daily just with my door closed (no towel under the door or groove toube) so it always has a hint of weed in the air, I would see and fix any light leaks at night, and would an air purifier refresh the air and remove the smell? and about the small harvest, how much do you actually get off of one plant? people have told me they get 2-3 ounces off a small plant and I could put 2 small plants one on top of another since my closet is pretty tall, and if I could get atleast 6 ounces it would last me a good while.
