Does it matter where my intake fan is? Another quick question also. +rep

Ive got my intake coming from the room outside the closet. So I have a duct out inthe room, running into the closet, connecting to the fan, then running a duct from other end, to inside the tent.

Does it matter where exactly the fan is for best results? Should it be inside the tent? Or at the very beginning of the duct? Does it matter?

Also would it make a difference if I turned my exhaust fan upside down instead of having it sideways? (pic below of how it is now). Curious because figured if I turned it upside down, it would grab more of the hot hot air, also would allow me to change some things around and give me more space.

yes u want to put it toward tha bottom where tha cool air is out air goes out the top where the heat rises

Ideally, you want your exhaust fan to be hooked up to one of the vents of your light hood. The other vent should be open so the fan draws air through the vent, then exits the hot air to the outside of the tent/cabinet. Of course, you need a sealed hood to accomplish this.

Or ... have I misread you? Is the fan blowing air into the tent from the outside? If so, what is the purpose of the outside air coming in? Is it to cool the air in the tent, or to provide a "breeze" for your plants?

Yes, but Im asking where does the intake fan need to be for best results. Im aware that the duct needs to run to the bottom of the tent, but where should the fan itself be?

The duct you see coming in from the side is the duct connected to my intake fan, which is connected to the duct that runs into the main room. It is bringing in that air to cool down the tent, as the tent is in the closet, and the closet doesnt get the slightest bit cold.

The exhaust fan is the fan you can see, with the duct running out the top.

Well, I really don't think it matters much as long as you have good airflow coming through the fan. Technically, I would imagine that the shorter the ducting, the more efficient the fan would be. But does it really matter as long as the fan is keeping the tent cool enough?

Thats reason I was asking. Tent isnt staying cool enough. Im taking back the AC unit I just purchased tomorrow and getting a bigger one. Plus my intake fan runs through about 15 foot of ductwork, so may try to find a way to shorten it.

The long duct work creates a lot of flow problems for the fans, shortening it up with help. I'm still a little confused about the setup...You should have the exhaust fan at the top of the tent exhausting hot air out. Do you have a fan on the intake? If not, add a fan to that too, it'll help flow. Exhausting directly thru the hood as said above is the way to go.

Yes.

The picture included with my first post shows the fan bungied to the top of the tent, with the connecting duct work going out the top duct hole.

The long duct you see coming in from the left side of the tent is connected to the intake fan.
