newbie closet grow setup

[Midgitt]

Alright heres the deal, a while back a friend gave me some seeds..it was pretty decent bud so i thought id give a whirl and plant a couple( lol i did so with no lights growing them in my window seal using backyard dirt) surprizingly they sprouted and i began to get a lil more serious, since then ive been reading on here liek crazy got a couple more plants sprouting using florucents, i was thinking about making my closet a grow room, as of right now i got my lights in there and a couple plants going at it, the problem is i need to better conceal it to keep low profile around my roomates, so i was wondering if there is any way i can keep my closet door shut during the day ...and open it at night for circulation, i would have a fan running inside constanly, and i seen a video online of a guy who put some sort of a spray on his plants for c02?
any help would be apperciated, i cannot vent into any other room, or attic, or outside, any help or commments would be great thanks guys, be easy on me

You need some type of fresh air.Some way the hot air has to come out.Your plants cant keep taking in that hot stale air.I would think every night would be a little too long to wait to ventilate or get some circulation in there.

ty for the reply
i had thought about maybe removing my door knob having a lil cpu fan in the hole blowing air out, i do know if this would be enough, or how to keep fresh air coming in, i would be able to open it through the day at different times, i mainly need to know if i did this, how often would i have to open up my door?
would pretty much heat be the only thing id have to worry about?

You would just have to worry about heat and your plants getting fresh air.You can use a cpu fan to bring in air but you need one to exhaust.So if u cant bring in the air cut a hole for passive intake and use the cpu fan do blow it out.4 inch duct fans are cheap too that would be able to help u out..

ty for the help, there still is another question i got, if i had about 4 plants flowering in there, and if i had a way to exhaust to the attic, how bad would the smell be up there? like my roomates know i smoke..i just really didnt want them to know bout the grow setup

I dont think it should smell that bad.But it will stink try looking into a diy homemade filter.
