Security vs. Proper Airflow

what is the best way to keep the window of the grow room (which has a grow box in it) safe from the eyes of neighbors and street, in terms of strong light (sometimes the door is opened) and the box itself that is positioned close to the window, and at the same time, maintain a proper airflow in and out of the window?

I used two thin pieces of cloth that make it quite secure for the neighbors' eyes (this is obviously the top priority), but the airflow through it seems poor and the room heats up (this is also very important of course).

any ideas on how to improve this situation?

in the future I will extend the cooltube outline duct to the window, but I'll have to put in on the window with the curtain around it probably, which is ok since it looks like a dryer duct. but not more than one, right? that would start to look suspicious. or am I paranoid?


(there are also electric shutters behind the curtains, they are open) (notice how the pink floyd poster is inside to avoid being suspected as a hippy grower)

At first I thought you could install some fabric in the window that is designed to allow air to pass freely though it. I'm thinking of the acoustically transparent fabric I have in my home theater screen. You can easily blow through it but in a passive airflow situation, which is what you have when you just open the window, your not going to get much flow.

So your solution is to get a dryer outlet, a piece of plywood, ducting, and black spray paint. cut the plywood to fit in the bottom of the window openenig. Install the dryer outlet and duct and spray paint the inside of it flat black. open the window, stick it in, close the window. You might also want to install a screw directly above the top of your window sash (the wood thing with the glass in it) so that someone from the outside can not open the window.

yep
thanks
i'm gonna do that I think. only thing is, the windows move from side to side (so when open they are facing each other, only half the window can be open). but I can definitely put a drier outlet in it, even without the plywood (is it better with? why?).

do you think spraying it black will prevent people from seeing it for what it is? cuz I need at least two of them, I think, and two can look a bit suspicious.
hmmm

I can put the ducts right beneath the window and have that curtain streched on them so they are actually covered by it from the side, but not from above!

i show a picture soon.

question: why does the duct fan have a part on it's outline side that narrows it from 6" to 4"? do I need that? this is a centrifugal fan - the diameter or the part where the blades are is 6", but both the entrance and the exit of it narrow it down to 4". only the exit part can be safely removed though. the question is, should i, and why is it there in the first place? see the photo

Build a box that fits right over the window!
Open the window slightly and fix it in place. (with screws etc, you only need it open about a finger or two width)
Get some Blinds, screw them in place and make sure they're closed.
I'd also suggest getting some kind of damp trap to place in the box to avoid any condensation building up on the windows.

If anyone asks why you never open the blinds, just tell them you use the room for storage and can't actually get to the window.

Hope this helps.

like arrid said... build a box to fit the inside of the window, have blinds or curtain inside it so it dosnt look sus from outdoors

then attach your ducts to the side or bottom of the box

the box should be light proof and pretty air tight

afraid i'm having trouble understanding! I have electric blinds on that window, that close from top to bottom. other than that, like i said, the window closes from side to side

so if i have blinds covering the box, wouldn't that cover the ducts too? or do i need an opening for the duct? in that case, what good is it to have the box on the window? (the open part of the window is rather small, way smaller than my box)

box coveres entire window
if the electric blinds stop airflow, then leave them open... behind them is a curtain just for looks
the box acts an an air intake for your ducts
keep your intake and output ducts apart so it dosnt just cycle the old air back in

oh i see now! i thought he meant a grow box on the window... yeah, i've seen this done in some video - he built a box like a shield on the window innerside. but still, having a curtain for the looks of it will reduce the airflow. but i like the idea of painting the whole thing black.

you can stick the curtain to the inside (back wall) of the box, so the air dosnt pass thru it.

the ducts can connect to the sides or bottom edges of the box.

the curtain is just so it dosnt look sus from outside
