smell of 3 plants in crawlspace

im getting ready to start my first grow in the crawl space of my house. my house has a weird crawlspace with about 6 feet of clearance and i will be able to seal it off completely from the rest of the house. will the smell of three plants be strong enough to seep through the hard wood floor of my house?

it very easily could....but what you need to remember is that if you seal it all off...how are you plants going to get oxygen? you would be better off venting the room somewhere the smell wouldnt be obvious...and add a a carbon filter

its a fairly large space. probably about 10x12x6 and i will have a vent using a fan from my small basement that is just for storage so no one goes down there except me.
