DIY DIY Carbon Filter

[dude]

No.....lol

Right,
Work out the room volume. 1x1x2=2
Cubic metres per hour m3H. If you are one of our North American cousins it will be Cubic feet per minute CFM

Its about every 3 mins you want the air to change so about 20 times in a hour.

So, 2x20=40cmh is the fan you need.

But, there are a few variables involved also. Like filter so add 20% to the 40cmh. Also what type of light you have can affect it but that might be too anal over it.


Hth.

Had this exact diy on another thread. Used it in my first micro pc grows about 7 years ago! Lol.

Worked like a charm for small areas!
