best type of fan?

[Mr pot Head]

What would be best type of fan to use for ventilation?
it's for a single plant grow box, not built it yet, but will be about a metre tall n about 60 wide.

have a few spare pc fans, will these do?

Yes, but it depends on how much light you have. If it gets too hot, you may need to break down and buy a small in line fan for $20.

You can get really cheap bathroom exhaust fans at the home de-pot for $20.. they move 50cfm... should be suffice.. get an intake and a outtake.. or you can get an inline also there for about $40... its a 6" inline fan... look in the heating and ducting section...

Cheap computer fans move about 20 - 40 cfm (it always says on the package).. 3 - 10$
You also have to buy a 12v adapter.. 10$

I think PC fans are great. For more cfm just line them up in a row.
