If you are not sure what size extractor fan to use, it's easy to work out.

 

Simply calculate the volume of the growing environment to the nearest cubic metre. This is done by multiplying:

Length x Width x Height = Volume of your room in cubic metres (m3) and then multiply the answer by 60 , then by 1.33.

Ideally, air needs to be replaced every minutes (or twenty times an hour). Therefore, just multiply the volume of your growroom by 60.  

For example, a room of 3 metres x 4 metres x 2.5 metres high = 30m3 and 30m3 x 60 changes per hour = 600m3 per hour. then x 1.33 to compensate for any ducting/filter/impact to extraction efficiency.

Once this has been calculated, you can select the correct fan
