Buyer’s Guide: What To Look When Buying An Inline Fan?
Now that you know the best inline fans for 2022, let’s look at the parameters you should consider while searching for the best inline fan for grow tent.
Size Of Your Grow Room/Tent

Also, ensure that it is not overpowerful so that it becomes noisy and produces vibrations.

CFM stands for Cubic Feet per Minute and measures how many cubic feet of air the inline fan can exchange every 60 seconds.
With the CFM rating of your inline fan, you can know if it is the right inline fan that can bring fresh air flow to your grow room.
However, before choosing an inline fan with a CFM rating, you need to calculate the CFM of your grow room.
For example, for a 4x4x6 grow tent, you can figure out the cubic feet as per:
Length x Width x Height
You get 96 cubic feet here.
According to it, you need an inline fan with a CFM of more than 96 cubic feet, considering the filter and other factors that reduce the air movement through an inline fan.
It is how you calculate the fan’s CFM, decide how much airflow you can achieve through CFM rating, and decide the right duct fan for your grow tent.
Noise level matters if the grow room or tent is established in a living area. For example, your bedroom or balcony.
