Cool air

Hi, I converted my box room to a grow room and had to blank the window off to prevent people from seeing the light and I'm looking for a way to bring the cool air in from the window without being detected. Can anyone help?

I've seen it done where people run ducting into a ply or OSB board fixed to the window opening with curtains or blinds mounted on the outside face to look like a regular window.

Or you could put in a fake window AC and duct through it.

I've got the curtain on then the board but the curtain goes from top to bottom so it's blocking the breeze and if I put anything between the curtain and the window, then people will see or the tight coming through

Vertical blinds then. Simple really.

That's what my old intake was. An open window with a box built over, net curtains to obstruct direct view with curtains slashed and an intake fan connected to the box. Worked great for years.
with my new intake in a different room I have tapped into the basement chimney with a 8"hole and will drop a 6" acoustic duct 10 feet down to draw air from the basement which is about 60 degrees in peak summer. Would have my grow down there but boiler and electric/gas meters live there.

If you cant tap into a chimney then build a unit around your window with a light baffle or light trap to stop light but an intake fan to draw air in.
