Airflow question when drying..

Couple questions..
I'm gonna be drying by hanging lines in a 8x12 room.

1.) I have a big CAN100 (I think) filter that I have standing up in the room with a 6" fan on top of it blowing air up towards the ceiling to get rid of smell.. Is this enough airflow? Or perhaps too much airflow?

2.) I also have a 16" stand-up fan, I can aim it at the floor or something.. Should I use it?

3.) I run bottled CO2 in my room. I just started flushing.. Should I still run my CO2 at peak levels during the next week while I'm flushing? Or should I lower the CO2 down a bit? Or eliminate it completely?

Thanks.

So the filter sucks & discharges into the room? you are using it as a scrubber?
This is a big room. I don't know the cfm of the fan, but I would think you would want some more air movement. Has this setup worked for growing? If yes, it should be enough for drying.

Sorry, I don't use CO2 - no clues on how you should proceed.

Well regardless of the filter/fan combo, I have the stand-up fan also in there, so for growing its worked great.

But for drying its a different subject. I need to know if the CAN100 filter with a 6" fan on top pointing at the ceiling is enough air movement, or if I should also use my stand-up fan and aim it at the ground or something too?

Plus weather I need my co2 tanks on during my flush..
