Question about inline fans in tents

I usually have ducting go through both sides of my 1000w and just going out of the tent, but this round I was wondering if it would be okay to connect the ducting to the other side of the inline fan and have the fan basically suck the air out of the tent through the light. I assume a lot of air will just get sucked through the open ducting holes and the tent will just suck in a little, but I was wondering if anybody else has had any experience doing this.

do you mean like this, i have no problems running mine this way

I don't use a tent, but a 5X5 sectioned off corner of a basement, and what you described is how I am set up. Fan sits outside the room, ductwork through wall to cool tube, and more ductwork from intake end of cooltube, which I just have laying on the floor sucking up air. Passive intake into room

yeah, I researched this beforehand also ....basically you almost always wanna suck as opposed to blow (although in another totally different subject "suck" and "blow" are synonyms)

The only thing about running the fan and light drawing air from inside the tent is the air cooled fixture doesn't stay as cold thus increasing the temp of the tent. This may be beneficial to people who need to combat growing in colder areas during the winter.

also didn't allow me to keep the hoods as close to the plants because of increased temps.

correct me if im wrong but my theory was my tent was getting hot with the way it was before because there was no fresh air coming in, sure there were fans blowing air around but that still isn't "fresh" air. the way im proposing will fix this by sucking air in from the vents and from the open ducting holes (there is a lot of them) I just didn't want to turn it on zip up my tent then watch it collapse on itself, but I figure the poles holding the tent up are strong enough they would break from a little pressure like a 6 inch inline fan, right?

and another thing I got bamboozled into buying a very shitty used hood from the hydro store and its practically falling apart and has huge gaps so when I run the fan pushing air a lot of air flow gets lost, however pulling in air would fix this problem.

Thats how I run mine. There are ventilation holes for a reason. That's why you get a fan anyway to cycle the air through your tent. That's why the cfm is so important.

I have a very small tent 3x3x5 and I have a ducting connected to AC that goes to the air cooled hood and out the air cooled hood (Not out of the tent)

this keeps my tent at a perfect temp of 75F

the odd thing is the AC is blowing only 72-74F (to keep noise down)

I like it personally, as when I shut off everything at night air still flows through passively and keeps RH & Temps at a stable 40-50% RH & 70-75F
