What size fan do i need?
Measure the Height, Length and Width (in metres) of the growing environment.
Multiply together (H x L x W) to give the cubic meter volume.
Multiply this figure by 20.
This is the size of fan required to change the air 20 times in an hour.
Buy the fan slightly above the figure calculated if possible to ensure adequate ventilation..
