Positive preasure VS Negitive pressure?

[ZuuTeD614]

So my 2x4 tent I run a 4 inch AC infinity fan for exhaust hooked up with a 67 Bluetooth remote. The tent is in my house where my AC stays about 73 my tent gets about 86 sometimes 87 when lights on. I run 414 true watts of LEDs. I open a bottom flap and keep a fan at the other bottom flap blowing in ac into my tent to keep Temps down to 84, but it makes my tent blow up. It's not super bad but it's noticeable. Is that bad?

Edit: also my tent is 84 inches tall, should I have the exhaust fan at the very top at all time or above the lights and raise it as I raise my lights?

exhaust fan will draw in the necessary air working alone i always do negative pressure because i use a carbon filter and negative pressure keeps all the smell in the tent and moving thru the carbon. also got my fan hanging at the very top of the tent.

Ok I don't really care if there is a smell in my house. But I know what is being sucked out with my carbon filter is clean. So having a slight positive pressure won't affect my plants?

no it won’t

no it won’t

Cool thanks man!

Slight positive pressure will make it harder for bugs to enter.

That's a cool thing to know,but I am inside so shouldn't have a problem with pest.

Famous last words.

We all battle pests at some point indoors. Especially if you aren't running a sealed setup.

True that man, well I hope I don't have to experience them, when I was set up in my garage I got fungus knats and solved that problem. I just moved tent inside about 3 weeks ago and haven't had an issue.

I seem to recall pulling air out (negative) having a bigger effect on the temperature than pushing it in (positive)

Edit.. By flaps if you mean the mesh vents they're nothing like high enough flow, get some 6/8" ducting and stick a midge net/filter over it for inlets.

I don't get what you mean midge/net filter over what?

Some inlets of ducting, the tent vents are not much use for airflow/cooling.

Ok yes I open up a actual side hole and put a 10" fan on the ground right by my floor vent so it sucks my ac when it's on and cools my tent off. It just blows my tent up a little it's not bad.
