I wouldnt.
Same.. You're good man, just make sure you got some good air exchange in the room and no stagnant air on the canopy.. keep it moving.. 3 levels of fans.
Low...mid..just above canopy.. keep the mold spores away

I just have above and below canopy personally. My 8'' exhaust setup pulls plenty of air to keep the mold out of my 5x5 lol.
Hell ya!!..

I have 1x 4” ac infinity fan sucking out the bottom into a can filter and 2x 8” ipower fans suck out into a filter...I wanted to get a 12-10” but if you look at the amount of cfm generated per watt 8” is by far the most efficient I’m in a 4x8 tent and my temps hover around 85-88f so I gota have 60-80%rh to stay within vpd range so I want maximum air exchange at that level of rh%

Can never have too much air exchange if my tent using crying becuase it’s about to implode it’s not enough
Haha.. I can dig it.. wife still asks.. is that safe? I'm like ya babe, the girls are safe.. gotta be honest tho.. sometimes I look at the corners for signs of stress on the poles .. when she's not around of course

I figure 1700 cfm being sucked out of my 4x8 tent I don’t need fans blowing on them but that’s just me

Why are you sucking air out the bottom? and what filters are you running? If they arent big enough, it doesnt matter if you have a hundred 8'' fans running, your only going to get a certain amount of air through the filter (and its typically less than they are rated for)

The filters are 30lbs each the 4” filter is tiny I’d say 10lbs

I’m suck ing out the 1000w xxxl magnum hood with one Which is hung about to the middle level and the 4” on the bottom and the other 8” from the bottom on the opposite side...the air flow sucks my hand in with resistance on the 2 8” so Their plenty powerful even if their at 50% restrictions that’s still 850 cfm

You know heat travels up right? You should be bringing fresh air INTO the bottom and pulling the hot air OUT of the top.
I agree with Joe..
Give it a try man.
I pull in the fresh air from bottom.. opposite side of the plants.. c02 is heavy and will hang at the bottom.. then exhausted from above canopy. The c02 will be lifted up under the leaves on the way to the top of before falling down on the canopy. You will lose more to exhaust if the air excange is to fast. The air pulling up under the canopy is good because stomata are under the leaf.. so it gives the leaf more opportunity to breathe in c02 in a non closed, c02 dense environment. I use two exhale bags.. I hang them opposite side of plants and above air inlet.

Yes I no heat rises.... I don’t have the. Clearance my ceiling is 80 inches tall my tent is 79.5 inches tall there’s no room for ductwork on the top that’s why I did it the way I did it like I said before I don’t care where the ducks are sucking out from 1700 CFM‘s is still 1700 CFM‘s

Every air molecule is getting replaced in that tent 7 times in 1 min....even with filters let’s say worst case scenario they only operating at 50% that entire tense air supply is getting replaced three times every minute plus heat not the issue.... I want the heat because I’m using LEDs you need a higher temperature for LEDs so the heat doesn’t bother me much I prefer it in the high 80s all I care about is maximum air exchange

Also I have over 100. Boa constrictor‘s in the same room as the plants I have Not tested my CO2 levels but it’s way higher than the normal atmospheric CO2 I got 100 things constantly breathing in that room and it’s a small room
