this may be a little impractical, as it is probably expensive, but i would suggest keeping your clothes in plastic zip-up garment bags (assuming they can be stored safely away from your lights). or for a less expensive alternative, you could go to a dry cleaner and purchase some of those thin plastic garment bags (that don't zip closed).

to answer your question, i do beieve that your clothes would smell if you left them uncovered, especially in a close space with a pungent strain. go for a strain that is recognized as one that does not have an extremely heavy odor.
