co2... HELP NEEDED BY PRO'S

hey riu

I just started co2 in my 4x4x6 tent with a 16'' wall fan blowing the co2 down on the canopy , and the tent is in a 10 x12 room , and in the room there also is a open veg area that is 2x4x3 and is on 24hour . in the tent i have a 6'' duct pulling air thou the tent back into the room out into a carbon filter {the ducting is only hooked up to one side hood} and a fan in my window pulling air out the room . i have the co2 running 3 times during light for 15 min at 1 on the regulator . .... ... will the ducting pull the co2 out the tent into the room and does the fan in the window and the carbon filter affect the co2

any advice would be appreciated

hi im planning co2 for next grow what i will be doin is getting myself a unis set up about £120 plus tank
but if i were you id turn all vent off just leaving inside fan on to move co2 around remeber to point fan at floor to stir it up as co2 is heavier than air and will sink to lowest point
