What to do about smell in a sealed CO2 room?

Room exhausts maybe twice a day for 10 minutes. Other than that its sealed. What can I do to contain the smell? Obviously I don't want to vent my CO2 filled room if I dont have to...

The grow is in the basement. Would it be a good idea to hook a canfan and carbon scrubber and just exhaust air from basement?

Can you just put a carbon scrubber and fan in the room and just no vent it out?

You say your room exhausts twice a day. If that is the only place the smell can get out, you just put a carbon filter on that exhaust.

hornedfrog, that is a good Idea. I wonder if it would work. I will have to test it out. Anyone tried this??

MF: Well thats not the only time smell escapes. Smells penetrate walls and floors, especially during the last few weeks of flowering.

Here is my situation:

I am a medical mj grower and setting up a room in the basement. I have a NON air cooled hood. It is the silver sun giant 48" umbrella reflector. The room is completely sealed off and there is no exhaust fan setup because the temperature never goes above 85. I am using a Sentinel CHHC4 total climate controller which regulates temperature, humidity and CO2 all at once.

My question is, even though I am a legal medical patient, I want to minimize the odor and chance of detection to thieves, etc.. How should I scrub the air with a sealed room? I don't want to waste CO2 if I don't have to. Will hooking up a scrubber and fan inside the room work?

I think the scrubber in the room would help reduce the smell

I'd say shut off of the CO2 during the night cycle, and vent your room during that time and keep your room completely sealed while the lights are on to keep your CO2 levels up. last I heard, plants do not need high levels of CO2 during the night. hope this helps

yes, plant dont need co2 at night. their releasing their own. never run co2 in night cycle.
2 carbon filters needed for this room. one to scrub air, and the other hooked to a controler that shuts your co2 off when u need to vent.(like when temps get too high)
also one of those dampeners that seal your vents when no exausting is going on.

I vent by opening the door. Your plants eat the co2 at light on and then give off oxygen ( fresh air) and your carbon scrubber on the floor is scrubbing the old air

Meds: my significant other and I both have bad allergies and they seem to really act up when my plants are respiring. An Elf carbon filter on a Can Fan cleans and moves the air and you'd never know what I'm doing. It's recirculated, cleaned and there's no odor. Hank

I scrub in my sealed room. I still smell it, but it was reduced immensely. I think the next step to remove odor completely would be a ozone generator.
