Quick seal room question

I was just thinking. Say you have a sealed room and you didn't want any fans so you oversized fan and carbon filter. You put carbon filter on floor of grow room. You supplement Co2. Ok here is the question does the carbon filter/ fan blow the Co2 back up in the air. Reason I ask remember Co2 is heavier then air so it falls. So theoretically if u oversized your fan and had a sealed room with great negative pressure u wouldn't need any fans to move Co2 back up in the air. I think a lot lol.

You can grow plants without supplementing co2 and without oscillating fans and such. So how do they get the co2 then? Well, if you have an intake and an exhaust, the current is real enough to supply sufficient co2. Maybe not completely optimal, but it works that way. With that being said, it stands to reason that upping the intake-to-exhaust current will increase the distribution of co2.

That does not answer my question. I know that about intake and exhaust. I run a seal room what I am trying to eliminate is my other fans. And also allow to co2 to hit the plants even more.

If your fan (the one attached to the filter) had a high enough return cfm to generate the same effect as room fans then yeah. However, it may be difficult to achieve that while still keeping the filter viable, since an excess or absence of power can screw up the scrubbing.
