A/C instead of air intake?

If a grow was built 2x4 with one exhaust fan 3 isolators instead of intake would just a A/C be viable or will a Intake fan also be required?

the AC has a fan, and intake fans are a no-no. they suck in dust.

yeah but intake air filters will eliminate the dust. Will the AC intake fan be enough for an area like 2x4 to 6 metres

use your ac and have passive intake. as long as your exhaust is pulling the passive should be enough

awesome thank you

If you are not supplementing CO2 you will still need a fan to bring in fresh air even with an AC unit. An A/C unit just recirculates the air in the room. The exhaust side and cooling side of an A/C are separate. Google something like "how does an A/C work?"
