So just a quick question that I can't seem to find anyone in the same situation. I have a closet in an apartment and it is an apartment with a flat roof and I'm on the top floor. I'm trying to run an exhaust fan in there but the only way to vent is through the back wall or the ceiling. Trying to see if it'll be enough space between drywall ceiling and roof to exhaust or should I exhaust through back wall? or is it going to hit insulation and not do shit?

I have the same exact situation. My closet happens to be next to a bathroom. The bathroom vent fan happens to be in a space where the ceiling was lowered about 12 inches for the a/c system and vents. There is extra space and both bathrooms are there, so each bathroom has a vent fan with exhaust to outside. I took out their old crappy, noisy fan and put the vent cover back up for show. There was only a single rafter I needed to go over. I bought the matching 3" tubing, an adaptor and ran my newly extended line over the rafter and into my grow room's newly cut hole to match the tube. I bought a new bathroom exhaust fan, attached it to the wall near the ceiling and attached my tubing. Check my journal to see the pics I just put up today of the inside of my closet. It all slowly came to me, kinda like creeper from my teenage days. LOL. Even if you had to vent into the empty space, there is usually an eave to vent the heat build up in the space separating you from the outdoors so heat doesn't transfer into your apartment. But without the built-in existing like in my apartment, you risk the neighbors smelling it. Trust me, I don't know what my neighbors are doing, but sometimes it REEKS of paint thinner and I know it's not anyhting in my apartment.

Another option is an inline filter and vent it out a window. Disguise the vent somehow, window fan, plant box, ect... get creative!

in my 2 bedroom apartment my closet where I was growing was right up against the sink in the bathroom. I made a hole on both sides, put my fan under the sink in the cabinet and left the cabinet door open. Then I just turned on the exhaust fan. For added points, upgrade the exhaust fan to something really fast.

As long as it's the second bedroom. It would suck to heat up the bedroom and try to sleep.

I guess I'm the real lucky apartment dweller with my access to the exhaust. I don't use them in either bathroom because they are so loud and inefficient ... the ones pre-installed when the apartments were built over 30 years ago. In my journal you can see my temporarily created veg room (for the moment) and it is adjacent to my master bathroom. So if I needed the exhaust, I can install and take over the vent from each bathroom for each section, rather than venting directly into the apartment. I hope your bathroom isn't the only bathroom, or that you need to vent while guests are in. But wouldn't your entire apartment totally reek by reventing back, plus the fact that you have to pay extra to re-cool the air. If you live in a cold winter area, that might work well, besides the smell.

can't tell if you're talking to me the whole way through lol, I have a 250 CFM can style fan, I put it under the sink then I turned on the bathroom exhaust. The exhaust fan masked the sound of the can fan and it goes straight up and out to the sky. The whole place still smelled like skunk, but me and my room mate were like 21 at the time and all our friends smoked pot anyways so they didn't notice that we were growing.
We also took packing tape, folded it a little less than half way so its still sticky and put it so it flapped over all the door's cracks. It drastically cut down the smell when we did it to my room and the bathroom. You just gotta keep the doors closed 24/7

Yeah, pretty much responding to that. But you do have an exhause fan to the outside like me. And high up too. If the bathroom connects to the closet you are using, as do both my veg and flowering rooms, couldn't you get to the fan? A fan up there means that there is space for the box the fan sits in and the tubing. If the tubing went in the direction of the closet, that would just make it easier to access for a direct vent outside. But why have the fan IN the cabinet under the sink? I put my fan inside the room to push out. But only using like 70cfpm. Seems to be perfectly fine. My Cat Genie puts out MUCH more heat during the drying cycle of a cleaning run and my 70cfm draws out plenty for both that and a single light for flowering. So far (crossing fingers, LOL). So you are now gain in a 2nd floor apartment?

well the fan was in the cabinet just to be kinda stealth, nobody ever noticed it was there because the exhaust was louder than the extractor fan. I guess I could have put it on my side, but we didn't really have that much room in there. I never really thought of putting a vent from the bathroom exhaust to the fan, its not really stealth. I put a push pin into the door so nobody could close it and it worked pretty good for getting rid of hot air. Only thing that sucked was the heat was free and even though we had a thermostat, it didn't work at ALL and it was so hot I was sweating in winter. It turned out to be really good stuff but it really looked home grown, kinda loose buds

Well, I ran my vent tubing from inside my closet through the ceiling and then spliced right into the existing vent from the bathroom exhaust that runs to the outdoors (above a second floor apartment is perfect). I blue-taped the opening I took the existing bathroom fan out, put the grate bck up with the fins facing the wall so guest wouldn't notice. I trimmed the tape from around the grate edges with a utility knife to hide it. I just tell people it's burnt out and I haven't told them yet about it because I have my own bathroom and that is seldom used. Were you thinking an open vent hanging from the ceiling to the fan under teh cabinet? What do you do now?

yea thats what I thought
now I use a 5x5x6 tent out of 1 inch PVC and panda film, works great you just gotta keep the window open a bit

You built a PVC frame for a cabinet and lined it? Interesting. I will keep that in mind. So what do you think about this: I keep hearing stupid shit about buying (rather than growing) supports terrorism of some kind in an almost third world country. So if it does, everyone should have a simple flowering-only setup. People that know how to clone can supply the clones needed for each person 8 week venture into horticulture, and then curing of course. But the idea is that everyone has a closet with junk in it they could part with and make a flowering closet. I'm hoping if I spread this kind of idea, we could one day reduce imports to nothing and the entire country will be self-sustaining a good thing, one house at a time.

I don't think pot supports terrorism at all. Pot is hard to hide, I don't doubt that some make it in though. Here a couple years ago, they found out the hells angels were running the plane's cargo at the airport and importing/exporting drugs from across the country through it but it was still only from across the country. I'd say most weed in the US either comes from BC, Mexico, or is mass homegrown in the US. Things like coke is much easier to hide, it weighs more for what you get so it's smaller, and the plant can't really be mass grown to make coke.

If you're in a cooler climate, it makes no sense to vent outside. Scrub the air and vent into living space and you will save a lot on heating anyway. Not sure why anyone's talking about smells... obviously a carbon scrubber should be first priority whether you vent outside or not.
If you're in a hot climate, and don't have an easy means of venting outwardly, I would do the same and add an A/C in the room you're venting into. Obviously no one's going to question an A/C running in a hot climate.
Honestly I would do that anyway just because I wouldn't want a plume of heat coming out of any of my vents 12-18 hours a day.

Depending on what lights your running and the ambient temp of the room the closet is in, you could pull air in from that room (low down) and exhaust into the same room (higher up). Providing you have a good filter and are able to leave a window ajar or you are able to run a an AC from time to time with lights on... You'll have no problems - STELTHY
