Scrubbing air and using CO2?

So I'm setting up 2- 8x4 tents, the question is how often can I scrub the air in the tents to get the odor out (with carbon filter) and remove the humidity from the air?

any help is appreciated~

In a tent, co2 is pretty much a waste. Tents leak like crazy.

Beside the obvious above.most co2 rooms are sealed. Inside the sealed room is your ac, deheuy, scrubber.

I've been running a co2 room for about 4yrs now.

Thinking abou buying co2 bag or co2 tablets and vent on all the time in tent for smell...
Is it a total waster or my plant will benefit from this...

What kind of scrubbing system are you using for your space? and I also don't really need the CO2 getting all the way to 1500ppm it's just that I tested the area and sometimes the CO2 gets below 'ambient' of about 300~400ppm.

I go by weight of carbon, not size of scrubber. I have 1x 80lb scrubber in an 8x12x7 room. I also use 3 more at various spots in my grow
