Hi I am trying to grow 1 plant spending as little money as possible while being a stealth grow. I have a box I am using that is about 1'x1'x3.25' and I installed a pc case fan to the top, and the problem is, its too loud. I was thinking of getting an amp counter and limiting the amperage the fan gets to keep it down, but I was wondering, how much ventilation do you need? If I only run the fan a few times a day, and possibly like all night, will I be ok with my plant getting enough co2. I am going to have 2 2"x2" ventilation holes, one at top and one at bottom. OK, due to the fact I need to put dryer sheets on the outward fan to keep out the pot odor, where would I go about buying something to limit the amperage? edit 3: ok ill try just making my pc really loud so u cant tell
