Would a micro grow thats 22inches tall 6 inches deep and 11 inches wide need a exhaust fan for the odor? I know ona block gel, ozium, deodorizing liquid, and carbon filters are used for odor control, but i heard an exhaust fan duct out a window is perfect for odor control. Are exhaust fans for micro's unnecessary?
Location of the box plays a big deal with me. I us no odor control only because my box is located in highest spot of house can only smell when u r next to it. So if in a closet in ur room odor control might b needed.
