1.2x1.2x2.0m Grow Tent Advice Please

Hey guys, this isn't my first grow I've done one before recently, still pretty new I've just bought myself a New Grow Tent Size in title, what I am wondering, as I'm on a budget and can't afford a carbon filter *smell not a problem* and extraction fans, I have a 7" desktop fan, inside blowing, if I keep the holes for extraction and filter open that should let enough heat out to keep it cool? I'm thinking of turning lights on tomorrow for few hours to see the temp, my mate is vegging for me so I not got any flowering atm,
Pictures Below:

All depends what lights you will be running as far as the heat goes, I'm in same boat as you and half way through flowering i just have 2 desk fans and leave vents open during light period, So far i havnt run into any issues but i am only running two 250 watt hps and 2 55 watt t5s so heat isnt really a issue for me. Hope that sorta helps.

I'm running a 400watt hps

It's good to know people when there are in same boat, as you can help each other out and I'm running 1 desktop fan 7".... thanks dude

My two 250s should be more or less putting out same sorta heat as your 400 watt id say. And we also are using the same size tent.

I have read a lot of stuff about people saying you must run inline fans taking waste air out of your tent and you must do this and that in order to grow a decent crop.

Seems to be a lot of myth i have found any way.

Good luck with your flowering mate post some pics up when you can !

Yeah I will not flowering yet my mate vegging for me and im flowering and I know it's not a straight forward answer but basically what should I be yielding:
400 watt HPS
Coco
11L Square pots
Bio Grow
Canna Vege
TNC Molasses
Superthrive
I know it's hard to say that's why I'm asking estimate rough answer you got pic of yours?

It really depends on a lot of elements strain genetics growing conditions ect i may not be the best person to answer that question sorry.

There are a lot of highly knowledgeable people on this site that may be able to shed a bit of light on your question but it is near impossible to tell until you have a dried harvest on the scales.
