extractor/intake fans

[Reef4]

hi, i have a grow tent, its 1.2M x 1.2M x 2M. i need to sort out some ventilation.i have a pedestal fan, im guessing i need an extractor fan and an intake fan.
basiclly im looking for my cheapest option cheap to purchase and cheap to run, also i need it to be quite quiet. can anybody suggest some makes and models i should be looking at? do i necessarrily need an extractor fan AND an intake fan??

Yes you do need these fans, lack of airflow will result in poor plant performance. As for what size fans you will need depends on your lighting. What lights are you using?
