recycling the carbon filter exhaust back into grow tent?

[11:11]

anyone tried this or got any thoughts?

does the air get "scrubbed" in the cf?

if the ducting from the cf out was long enough, would it cool enough to be send back through the intake of the tent?

just an idea i had as im building my room just now and was settled on a passive intake but while im at it cutting plasterboard, attic floors etc if it would work id be better doing it now.

it would cut down on shit coming in from the intake, bugs etc, and as the cf out is in my attic (cold) would stop any heat issues for the eyeball in the skyball.

or is the air out stale and needs fres air into intake?

cheers

only thing is doing that, like you say the air is stale and humid, so co2 will be depleted, and adding moist air to ya grow room in flower would not be good.

Not a good idea. For one the air will just get hotter and hotter and hotter if all its doing is recirculating the air. And if you're doing that. You may aswell just have a few circulating fans and forget about intake and extraction all together as thats effectively the same.

You need fresh air for fresh oxygen/co2 etc
