I had issues with a major risk to my security on my old yt channel earlier this year mate so I made a new one once all was sorted, there's a link to my new channel on pg2 of this thread
. I'm KushMunkie over on yt.
And my flower room ventilation I've taken a few pic's of to show you how it's set up....
^^ Here's what my pics don't usually show lol, the upper half of my flower room.
^^ My intake fan is pulling air in from outside through this boarded up window here, the window is left slieghtly open to let air in and from outside, this window looks just the same as any other window too, my room can not be seen at all and from outside you'd never guess whats goin on in here either lol.
^^ My carbon filter is suspended from the middle of the ceiling as is my extraction fan bolted directly in. lol I need a new filter cover too....
^^ Ducting from the extraction fan is then fed up & out of the room here into the loft space.
^^ Both fans are controlled by this, which turns the fans power/pull/drag up or down depending on room temp's, i.e. the warmer it is the faster they run, more cooler air then they power down. all automatic at the temp it's set at.

I used to use a grow tent but found them very resricting as height can be an issue with them and now I'm using a full room I'd never go back tbh.
