Plants provide a good cover smell

So I've recently found a good place for a personal grow and have a few questions. I was thinking of venting out through the dryer exhaust. There is also a good sized garden right where this exhaust blows on. I was planning on doing a filter using kitty litter on the inside, but im looking to plant some flowers and herbs in my garden to provide an additional fragrant layer. what flowers and herbs do you grow which provide a nice olfactory high?
its an area which gets good morning sun and afternoon shade.

there is no substitute for a good carbon filter. I would suggest that cheaping out on this is not the best idea. A carbon sock will run about 80 bucks and last about a year. in fact mine has been on nonstop for 14 months or so.
Venting out the dryer vent is not bad but managing and controlling the airflow may pose to be more difficult than you think.
Throw a fabric softener sheet inside the dyer vent from the outside of the house every two days if ther is more odour than you want.

yeah i was wondering how i would be able to make sure the hot air from the dryer doesnt run backwards into the grow...

i was wondering about cover plants as much so the garden out back looks and smells good as for cover.
