Which Size Kit Do I Need for My Grow Tent?
Find out the volume of your grow space in cubic metres: width x length x height = volume
For example: 1.2m x 1.2m x 2.0m = 2.88m3
You'll need to have the capacity to replace this volume of air once per minute. Multiply the volume figure by sixty to work out the airflow needed per hour.
2.88m3 x 60 = 172.80m3
Carbon filters add some extra load to your fan. To account for this, multiply the required airflow by 1.2, which will give you some spare capacity.
172.80m3 x 1.2 = 207.36m3
Note that it is always better to over-spec your fan and regulate it with a controller. This gives you the flexibility to increase output levels if temperatures rise.
