The previous phat filter I got was 25" tall and like i said I sit in on the groun of my 6 foot tent. Is there any difference in a 16" carbon filter sitting on the floor?? I kow the 16" carbon filter will fill up faster. My main concern is will the tent air circulation be any less or more with the shorter carbon filter. Thanks

Shouldn't make any difference as far as volume of air but most people put them at the top of the tent as that's where the hottest air accumulates. Having it on the floor means you're pulling cool air out of the tent instead of the warm air up by the roof.
How do people put inline fans at the top of a small 3x3 tent? The light gets in the way.

Does that actually make the tent much cooler with the inline fan up top?

I've never had a 3x3, in the 4x4 I used to use I had it up against the side and it fit just barely by the light at the lights highest point. Since we've gone legal, I just have the exhaust hose at the top opening of the tent and don't use a filter anymore.

I've never run my tent with the exhaust down low so I don't know how big of a difference it makes. I know when my carbon filter got older and clogged I had higher temps due to a decrease in air movement. As long as your temps are good I'd say put it wherever works best for you to access the plants. The other reason I wouldn't put mine on the floor is I needed every bit of floor space for plants.

Put the carbon filter and exhaust fan outside the tent, run duct from it in to the top port on the tent. Have the exhaust fan round the other way so it sucking the air out. Bottom left, number #4 i do this because my fan and filter is about 20kg/45lb plus the weight of the SE7000 is too much for the cheap tent and plastic corners.

Also you can put the foam prefilter inside your carbon filter.

As long as you have good air circulation in there the air temp is pretty even all over so shouldn't matter where you place the filter. In a small tent you need that space up top for the light. Some peeps put the filter outside and blow air into it which it is not designed to do. Still will work but make sure you have a filter over the intake so the middle doesn't get plugged up like my buddy's did.

well physics say that warm air is lighter and it travels up. you can test this with a termometer if you put it at the bottom or top you will see a huge difference in temperature soo fan at the top is better. you can put the filter on bottom but the 2meter line will slow you down

Or buy/make an inline filter. I put my filter in a cardboard box to make an inline filter. The filter's flange passes through the box and connects to the fan, a short duct connects the filter box to the tent. No unfiltered air pulled through the fan, no air blown into the center of the filter without a pre-filter.

I would never recommend anyone place their extraction fan and CF outside a grow tent, yeah, doing that completely negates the reason for using a CF, crazy! Why, because no ducting will keep in 100% of the smell leaving the grow tent before it hits the CF, and believe me running smelly weed through your exhaust fan before your CF will sooner rather than later always make your extraction fan smell like weed no matter how you clean it if you are actually growing good bud!!!

I run my 8 inch infinity @the top of my 5 x 5. It is overkill because an inline fan rated at 805 cfm is never run above setting 3 of 10 but, not loud at all. If I ever ran it at 100% would probably crush the posts. I have run the setup 3 times and I would not change anything in the setup.
