Difficulty figuring out how to ventilate.

Imagine a HUGE grow operation, 100's of plants using ALOT of co2 with only minimal fresh air entrainment. That;s going to need co2 enhancement.

Your setup? not needed, you can stop with that part completely, although I will give you credit for reading about that, understanding the need your plants have for co2 and incorporating it into your setup. But it's not needed for what you are doing.

Yeah I see what you mean makes sense. Well if that's the case I'll take out the two gallons I had it also worried me that they were inside the tent. I thought the heat would vaporize the water cause humidity to rise.

Just replace the 2 gallon co2 with a 2 gallon smart pot.......see what I did there?

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

that fan should be fine.. u gotta test it out tho..

and put your fan ontop of your filter. so its sucking air threw your filter.. and then just use the ducting to exhaust that air.. u can exhaust it out of the house.. or into another room.. or whatever works for you depending on your setup.. just make sure that the air that's going into your tent or room.. is coming from a different area then the air your exhausting because u will deplete your co2 and have weird issues.
