need help with grow box

I have finished setting up my grow box to the point that I have two plants growing right now and everything is completely done except for something to get rid of the smell. My plants don't smell yet and probably won't for a while and the grow box is a gutted cabinet in a shed I was wondering if I would even need a carbon filter because no one ever goes in the shed its a big shed the size of an average bedroom I guess. Would there be a possibility that you wouldn't be able to smell them outside the shed even if there's no carbon filter because there is so much space for the smell to be diluted. The only concern is there's a trail to a park right behind the shed that is used often would the smell make it out there? Also ig I need a carbon filter/scuBber where would I get one . Any feedback is appreciated

I'm curious about the smell of two plants as well. Just how bad will 2 plants smell/?

I am here to tell you that depending on strain 2 plants can be stinky. Maybe not now - but during flowering. The smell will waft onto the trail bringing interest to your shed.

your plants dont even have to be stinky for someone to smell them. The perfect combination of wind, humidity, and temperature is all it takes to get 1 smell up the nose of the wrong person. Dont get busted trying to save 150.00, plus it will help you sleep at night.
