I would suggest looking into ona gel and considering using that combined with a carbon filter if you really want to do this, but seriously slow down and think about this for a minute:
I assume that you have 0 growing experience and you are not sure if you will be able to contain the smell. You are not close with your roommates and you do not know how they will react if they catch you growing. Growing smells ALOT more than smoking does. Remember how hard it was to hide smoking from your parents? I highly, highly, doubt that you will be able to hide all of the smell from a grow from the people living with you. All it takes is one little slip up and your housemates could call the cops on you. How do you plan on getting in all of the equipment into your room? It would be suspicious to bring in carbon filters or have someone deliver a big ass grow box. I'm not trying to bust your balls here, but I just don't want you to get caught. I seriously recommend you wait until you have a place of your own.
The best thing you can get are these...

They are made for sewage plants and stuff to suck up smell. But since I'm guessing you don't have time to get one of those just do what everyone else is saying, Open all the windows, light a match, smoke a cigar then spray some febreeze.
thank you so much this gives an idea. carbon filters are too expensive here. i think i can close the door don't let any air go thru to house, open the window. put a fan so air goes outside. and put this gel and reduce smell a lot. i mean i hope i can. but can people smell it outside? thats a concern.
Oh I thought the idea was to take the air from the vent and push it through the bucket so the bucket of ona gel will deodorize it. So i want the fan pointed away form the bucket?
Also and recommendation on which smell to get? https://www.amazon.com/Ona-Gel-Pro-30-oz/dp/B00AC1N4DM/ref=sr_1_3?ie=UTF8&qid=1511129479&sr=8-3&keywords=ona+gel
30F is when a lot of strains start to smell. Most stinky smells are just the weed. But if you specifically smell mold then thats when you need to be worried.
If you dont have a carbon filter ONA pro gel is next best thing to manage the odor.

I would recommend ozium spray... it neutralizes most smells really well. https://www.amazon.com/Ona-Products-ON10061-25-8-Neutralizer/dp/B00AC1N4DM this stuff works pretty good too.

Carbon filter and a few of jars of ona gel around the house will help
Pasting this from another thread:
^^^ This stuff works, specifically this one. Dont bother with any of the sprays or other scents. Ill open this up with the windows closed and let it circulate before I start a indoor session, get my stuff ready then ill open the window a little. Ill finish my session and open the window full to clear my room, seal up the tub and close the window. I love with people and people come to visit and dont notice at all.
4) I dont take any of those precautions in my car. (Though I wouldnt recommend vaping on a solo in a car). Ill have sessions in my car with the windows up and air on circulate and it wont smell when im done. By the time I get out of my car and open the door, I could go in the house, change my clothes and take someone in my car without them noticing a smell as long as I didnt spill any bud.
get some ona gel and put it where the smell is coming in.
Ona Gel kept outside the closet will neutralize any odors that leak out into the room. If kept inside the grow closet you may have chemical-tasting buds.

Put one of these in front of the fan outlet opened only just a little bit
ona gel, for all your smell cover up/removal needs.
This is the one I purchased. It smells great. Haven't tried fresh linen yet.
Yup, pretty much. It kinda eliminates the smell also instead of just covering it up.
Here is it at Amazon if you want to read some reviews.
Ona Gel is my favorite way for getting rid of smells. We had a drunken friend vomit in our car a few years ago and this was the only stuff that worked 100%. I just put it in a tiny plastic bag and tape it wherever the smell comes from (ie: litter box, waste bin, pot stash, etc.)
