That’s basically how I have my fan in the 2x2 tent!
I have a small 8” fan blowing air around inside with a small passive intake in the back and my exhaust out the top with the fan sitting on the top of the tent! Hasn’t done me wrong yet!

Sounds similar to how I do mine too. I have the back Velcro flap open, 2 clip on fans from Walmart clipped to the posts blowing across plant tops, and my exhaust fan strapped to the top bars and exiting out the top side port.

Thanks guys! I didn't know if I was somehow better off feeding putting the fan inside somewhere and snaking the hose out some other port. The light won't ever come on so I'm not worried about venting heat, more the humidity from the leaves and pot.
Use one of the intake vents instead, not the passive ones. Run the flex duct into the opening with 2' min extending outside the tent. You keep the light out by using the duct. At the opeing of the duct outside of the tent, you place some of that blue pre filter media you get for your furnace. It's like a nylon material.
Cut the same diameter as the duct and place it inside and crimp it with the hose ridges so it stays in place. The purpose for the blue media is two fold. Filter air going in and keep the light out.
Disregard my light comment, but you could still go that route and filter the air in.

I don't need to filter the air at all, and at 100CFM I don't want to slow down the airflow, but you want active intake and passive exhaust?
Not in your case, I would keep it as is knowing your setup now.
Good info for keeping light out. I don't really have that concern so I can just open the back flap. I'm in a walk in closet so there's no real passive light I have to worry about.

Oh okay, thanks! The only thing I'll add is a baffle box for light.
My tent is veg and flower, so I'll get pics of how mine is setup. I have a 6" hose coming in from the lower intake hole, which is my makeup air. It has the filter media on it. My Infinity fan draws a lot of air and sucks the sides in real nice. If I used the passive intake I'd always be closing and opeing the flaps with the lights.
My fan sits up high like the others and pushes the air out, through the opening at the top, also with media inside the duct. So since you dont worry about light or heat then the flaps are better to keep open at the bottom as you have it.

I don't have any large round vents down low, just a small one for cords that won't fit a 4" hose, otherwise I would use a piece of the hose for intake as well.
OK so I guess you are concerend about light. I thought yours was tucked away as well like farside. Hence the baffle box. Got ya now.
I also got around to making my bud washing video! It took a while and is my first “tutorial” type of video so I’ve got some work to do but I think it turned out ok!

As if I don't sub your thread! Been there, liked it

Lol!! Well said brother Shed it dragged on a bit as I wasn’t as prepared as I should have been but knowledge for next video! HahaAs if I don't sub your thread! Been there, liked it

Baffle box is a good idea then to prevent that light!
Interesting about the openings. What size tent is it again? The pic makes it look bigger than it is I guess. Farsides pic is a good example of the lower opening where my duct would come in. It sits flush with the tent wall on the inside and both drawstrings cinched tight. JFYIO.

It's a 2x4x6. Good for two plants and a MarsHydro SP-250!
Here's the baffle box I made back in March. I'll see if it will work in the current configuration. Otherwise...boxes I got!

Great idea and nice design. You could always race mice if it fails.

In the tent - quieter imo, but more heat in tent bc of motor.
Outside tent - louder, lower temps inside tent (kinda null if you are getting enough heat vacc'ed out).
Controls accessable.

Thanks nobody! No light so no heat. In the garage so noise isn't an issue, as it's even quieter than the vent fan in the ceiling. And no controls available . It's either plugged in or it ain't. I was more concerned about whether I should be pushing or pulling.
Oh, and whether more hose length makes the fan less efficient.
