smell problem! please help

have a major problem. i've been growing these plants in a wood box in my room for the past few weeks. I have one exhaust fan that is built in in the back of the box to supply the plants with fresh air and a hole for the air intake since i was unable to get another fan. the fan hardly does much and puts out an extremely low amount of air preasure, (you can hardly feel it) but it does do the job. lately i've been noticying my room is beginning to smell like pot, so i bought some air fresheners to hang over the holes, in a hope to hide the smell since the plants i believe might be starting to bud. does anyone have a solution to my crisis?! or know of a great kind of air freshner i could get at a local store??

another thought..

what i dont know how to do is hook up a fan to an outlet. they are all AC current and not DC so i've had to hook the fans to a Ac to DC converter. which only transferes out to 6 volts cause it has a block on it. and the 6 volts bearly runs the fan. that is my real problem, i cant find a quiet little fan i can hook up to an outlet!!! are there any out there????

ONA gel is a great odour masking device. try to find a bigger transformer, 12v if possible, look in thrift stores or old electronics you might have lying around. good luck
