Sealed room, how do you scrub?

Sealed flower room (4) 1ks in 9x9x8 tent. What's the best way to scrub the air?

CO2 is added in the room so it would be nice to maintain an efficient means of delivery. One vortex 8" pulls air through (4) air cooled 8" reflectors with an inlet on one side and outlet on the other side. There are 2 small oscillating fans on the lower part of the tent circulating air.

Temps aren't too bad for the need of an ac at the moment, still playing with things.



Had the idea of attaching a can-75 filter to another 8" vortex 747cfm and just have the fan suck air through the filter and circulate inside the tent, no ducting leading outside. It would be turned on by a timer for a certain period of time, would have to play around with it during flowering.

You've got it! Best way to polish or scrub the air in an enclosed environment is to attach a fan to a carbon filter (either mounted above or standing on the floor) and let it run. Good luck!

I use cheap ebay 4 inch fans and filters for this, i run filter-fan-filter for my scrubber with no ducting, im not sealed but every bit helps
