yeah I realized that but would the inline fan be enough for the grow tent I have it's 190cfm these are the tents features. 5 Vent Holes (1) 4" Diameter (3) 6" Diameter (1) 8" Diameter.
Dimensions 6.6' x 4' x 2' (H xW x L) / 2 Windows 12" x 8" I also have a fan control connected to it
This is what I meant by room changes as your cubic footage = 53sq foot. So that means a 190cfm will change the air in the room at little less than 4 times a minute by continously sucking in thru the intake and venting to the exhaust.
There are guides out there and some suggested starting out between 5-10 changes per minute as a starting guide...Usually, always outliers, but increasing your room changes of air.... [aka more airflow] will dehumidfy by its nature. Decreasing air can remain longer in the room and become "stale" and hot, before exiting, in some cases increases RH%.
So with the info you have supplied: mid 70's, low 50% Rh?,your golden,.....if you have been using that fan.
Good growing
