Help a new indoor grower figure out his ventilation!(w/ diagrams)

Reposted from "New Growers", I suppose this is the more appropriate forum:

Howdy good people of ICMAG.

I was looking to get my closet started. I am in the process of moving into a place with a closet with a window, 3 feet deep, 6 feet wide, and 9 feet tall. After asking you guys, I am planning to start with a 600w HPS and add another 400w or 600w along the way, and maybe a mother/clone room a little bit down the road.

Right now, I am trying to figure out an integral part of a grow room with connoisseur grade potential: VENTILATION.

There is a window in the closet to a pretty secure location outside (the window could use a little bit of camouflage - its medical, but I'm paranoid). The window is 16 inches wide and 22 inches tall.

MY BIG ?: Would there be a way I could intake fresh air from outside and outtake fresh air with the same window with potentially 1000-1200w going in the space I have?

Here is what I was thinking. The walls highlighted in red can have holes put in them. The intake would be from the kitchen pantry right next to the closet (would pantry air be worse than fresh air as an intake?). The outtake would be out the window.

I place a priority on quality over quantity, so if I have to scale down my wattage to produce grade AAA buds with the closet to accommodate the effectiveness/noise of the ventilation, so be it.

How would y'all do it with the closet given. Thanks, and bom shiva!

Well, you of course do not want to be ventilating straight outside, at least without filtering the air first. All you would be doing would be pushing the smell of weed right outside of your house. I have never seen a closet with a window either, ahah.

What is behind that wall on the opposite side of the door?

Another apartment, so that wall is off limits. I would definitely use some sort of smell, light, and noise control solution before venting outside.

Right now I am leaning towards intake and outake from the closet window. Outtake going through a 6 inch fan hanging with bungie cords through 6 inch ducting - air straight from the 600w hps light out the window. Intake would also be a 6 inch inline fan, with ducting to vent the air directly to the plants at the bottom of the closet. What do you think?

I think the closet in the other apartment is going to have a 'whooshing' sound emanating from it...

I have two spaces this size. They each have 1200 watts in them. I have also placed the ballasts in the spaces as well for stealth. I use no supplemental AC. Just my normal AC for the house. I have a passive intake at floor level (a 6" hole in the wall that is light tight) , and a 6" inline fan that sucks through a carbon filter then into the lights then out of the room. Right now in the summer they are staying anywhere from 82 to 84. If you remove the ballasts from the room you can take 5 to 7 degrees from that (that is not an option for me though). In just a couple of weeks when temps go down outside my temps will be anywhere from 76 to 79. You do not need an intake fan. It is pointless for what you are doing. It will just be more noise, and something else to break. Also you will want to use insulated ducting, and insulate your inline fan as well. I just wrap the shit out of my fans with insulation and gorilla tape them. It cuts the noise by about half. I did build my rooms from scratch so i also insulated all of the walls. You have to put your ear to the door to hear anything. I used solid wood doors though. They make all of the difference. Also I made a black and white poly door with two zippers in it that you have to open once you open the regular door. It helped a little bit with sound because of the air gap between them, but mostly it made it so I did not have to spend a couple hours a week checking for light leaks. That foam insulation for doors only lasts so long. It is much easier to just put up the poly then foam the door. You will not have to tweak out as much with the foam. that way you have redundancy as well. Something else to think about is that if you are going to use those yo-yo hangers then I would also add chains for backups. Just incase the yo-yo hangers fail. They are cheap and are not constructed very well. I ended up just using strong chain and shit canning the yo-yo's. I forgot to add that I use insulated lite covers to help keep my temps down. I buy a standard insulated light cover, and then I go to the hardware store and get the silver bubble insulation that looks like the sun reflectors that you put in your car dash in the summer. I then cut the insulation in sheets and put two sheets in between the insulated light cover and the reflector. I dropped 3 degrees with doing it that way. 3 degrees can mean the difference between happy plants, and pisse doff plants.
