How do you have your tent setup? Pics might help with the experts on here.

That is fine. Passive intake is all you need. A little pull in is good. Will fully replace tent air in a minute or 2 which is good. If a strong fan with dimmer just back it off a small amount. Open all lower vents.

If you’re using a filter you want at least a slight negative pressure condition. This makes sure that air is coming in through seams or leaks in tent and everything going out should be through filter.

That being said, a lot of negative pressure will be hard on your tent. I agree with storm, if your passive intakes aren’t open start opening until there’s only a small amount of strain on your tent walls.

its sucking inward pretty strong even with a fan blowing air directly into the tent.

Can you dial back fan? It also should be above lights. Open EVERY free vent for passive. Can be pretty tight and still be fine. Complete air exchange in a minute or so is great. As @dbrn32 said tent suffers more than plant. A good tent no worries. A cheaper 1 maybe if outrageous. And as he said that negative pressure funnels the exhaust through the filter. A good filter and zero smell practically. Heavy exchange also allows a lungroom environment to work great. If keep that in line…easier…then tent will fall in line.

the inline fan i could prob dial back i just added another duct for direct airflow it relieved some pressure luckily i have acinfinity so its pretty solid.

Cool setup @keryilias

As @Storm said… You’ll want to open up a bottom vent… I open one round lower one opposite side of the exhaust side.

Is the 6" exhaust?

Then set the AC Infinity controllers fan setting at around 5… As @dbrn32 said… You want the negative air pressure(walls sucked in a bit) it makes the air filter function and sucks the stink out of the air. You can buy extra bars for around the middle of the tent to hold back the sides a bit.

@keryilias @Storm @dbrn32 @DanB I hope you all have a great weekend!

I usually have four plants in each ac infinity 4x4… And veg for about 8 weeks… It gets crowded!

FYI… The only issue with the bars…one goes across the doorway… Can get in the way.

Well i would not veg that hard for sure. Those are moving to flower soon as replaced. I can get 4 very nice 5 gallon pots auto or photo. Straight up grow. top/fim over lst for the usage of height space over base square feet.
I can get 1 20 gallon pot and photo wall to wall lst/fimm. Scrog net works wonders on a single wall to wall photo. Biggest haul was a GG4 mother uppotted to 20 and given the 3x3 to herself. She netted 2lbs DRY with a lot of popcorn i cultivate for oils adding maybe 8oz. SUPER fimmed. Wall to wall. HLG 550r. This was a 6 month veg. I am currently getting ready to up pot a Kush mother to 20 and do it again. The pictures are up here somewhere. Maybe on @MeEasy first thread. At least 3 years back.
