In a tent 3x3x7: If you used a cooltube by carbon filter>ducting>cooltube>ducting>duct exhaust fan...., I noticed a handful of people set it up this way, but wouldn't odor still get through? If there is any openings (are they air sealed?) in the reflector. Wouldnt air/odor pass though and out the exhaust without being touched by the filter? Or would the ventilation be strong enough to pull it all through from the filter?
