Co2 worth these conditions or not?

I plan a 2x2x5 hi-rise tent, adjustable speed inline 4" exhaust, and Hydro crunch 2' 4 bulb T5 H.O fixture to start. How can co2 build up if exhaust fans are always on? Was looking at co2 dispenser canisters from TNB Naturals, supposed to last 2 weeks or more. Is it worth it to provide co2 if there is already an exchange of fresh purified air, and if so what would be acceptable?

Not worth it without the room being sealed up, and for sure not worth it with fluorescent lighting imho.

If your growing inside an occupied house the co2 levels are pretty high already.

Maybe get a co2 meter first and see if you even need it.

Also co2 is only really helpful at the peak of performance .

High power lights, lots of food, heat and no defects. Then co2 and have tou another 10%.

I doubt youll get any useful effects at this point. Especially if your room isnt sealed air tight

Thanks Everyone. I figured that would be the case. There's no way for me to seal everything up and still keep temps correct. I only tried Co2 once a long time ago and it was a disaster.
