Ventilation in 3m x 2m bedroom

[pepe16 409]

Hi Gals/Guys/Trans/LBTQ

 

I've got a 1mx1mx2m high tent.  I have 5 White Widow, some of various crossings.   The environment is in the tent above, and I've had a 4" swiftair extraction running 24/7 plus a Honeywell floor fan set at 2.   I have a Rhino thermo controlled extractor, insulated ducting, and a black orchid intake fan, and all the fixings, to be fitted this evening.   I'll get the filter set, and duct to extractor.

My question is, should I open the window to vent from tent or into tent?  Bear in mind I get a lot of helo activity,  but they're pursuing suspects, not flying casually.    But a rel got caught in an industrial grow!     Apparently, it was the stench!...

So, I've 5metres of insulated 6" ducting and a thermo controlled fan.    Should I crack window open and vent (outwards) through there,  or just vent into room, and leave door open for fresh airflow?     And for intake, any ideas on whether just to open the window space thing at bottom of tent, or use a 4" intake fan, and should the fan be placed close to cracked open window?

I've tried to search threads regarding this, but always come up with a blank, so my apologies to those who have already posted answers.  If you could give me a link to ex fan set ups with filter inside, that would be great.  And also, as I can leave grow room open with fresh air coming in through bathroom and toilet,  should I use the full extractor ducting to blow into room, rather than out the window.   I live in an area of society where overhead cop helo activity is frequent!  I can't stress this enough. 

Any ideas would be most welcome.  Plants have passed 4 weeks 12/12 and are developing very sticky buds.  Photos later.    Thanks 420.  Peace out.

Ideally you need to vent out of the room all together as its not ideal to just leave the wino open & have a passive intake from that & at the same time,

your pumping the scrubbed air back into the same room which will have a higher humidity & this can cause other problems.

 

I'd be more inclined to block the window off altogether with either a bit of kingspan or a sheet of wood & cut a hole in that to vent out off (you need to leave the window open before bocking it up) 

 

can I just ask, what type of light will you be using ?

That's what I did.

Top left is exhaust from air cooled hood.

Top right is exhausted from carbon filter.

Bottom is intake for the whole room.

It's not ideal to have the intake from the same window as the exhausts, but it works for me.

Also this way I can work in the room with lights on at any time.

Window is open and a net curtain doubled over on far side of the mdf.
