ifn this is for your warehouse grow ozone generator is what you'll want also increase your air flow coming into grow and exiting. do you run lights at night or during day if day i suggest run them at night
The Answer:
Run the biggest,high-draw can-filters you can,inside (venting back into) the room.
One 4' can-filter with an 800cfm fan per 4m2 of garden will stop all odor,in it's tracks,immediately.
Rez Speaks the truth,
This is the same as what i said in the 4th post and is indeed the WAY to do it, i do it and it works, simple.

You're welcome.
As for ozone,always use it to scrub exhaust,never in-room.
And "air-cooling" the lights works best if you pull external air over them,not push air over them.
The hoods should be absolutely sealed with aluminum tape.
Factoid: Air-cooling the hoods doesn't make much of a difference,overall.
Factoid Two: Air conditioning and de-humidification are the Key Elements to success in a grow like yours.
(45-50% RH at 77-82f with average ventilation and no added Co2 is about right....)
Ozone won't do anything but mask a small portion of the smell with chlorine-like odor. In this large scale application, the problem seemed to be the smell ultimately leaking outside the structure into the warehouse where your reservoirs and warehouse-exhaust are located. Running a filtered exhaust out and then right back in as so many have suggested will obviously only help combat the odor contained in the actual inner-structure, but will do nothing to address the negative pressure, as sam said, that is displacing outside the structure. You need to physically exhaust *some* air from inside the structure, to outside the building, in order to create negative pressure and prevent displacement. You must run an active, filtered exhaust to some degree otherwise you'll encounter stinky-air displacement from your structure.
