Sorry for the late reply my friend.
Hope you are doing well.
In order to get negative pressure in my rooms I had a larger exhaust than intake.
A 4" turbo fan for intake air will be plenty for your size.
6" with carbon filter for discharge is perfect.

Welcome to 420 @rehabilitatora420
In a 60x60, your 350cfm will draw enough air through so long as you keep the bottom vents fully open and have a circulating fan inside

well the conditions wher the grow tent is located dont have fresh air all the time thats why i need the Active system with two vents for example if i buy exhaust fan with 2 speeds Air flow max (m3/h): 330 combined with filter suitable for it like max air flow 330 and then get inline at the bottom hole with Air flow max (m3/h): 220-280 do i need to buy a fan speed controller and if i do how its work i cant get it i connect it to one of the fans and controll only lets say the inline one wich will not have two speeds like the bottom one the climate in my country is 31C atm the led lamp i got have two buttons for growing and flowering and for flowering i think it will produce more heat so i need to be able to controll somehow the temperature inside the tent thats why are the controllers for as far as i understood..

well i'm planning to get from a shops in my country there are several and at the moment i have picked exhaust fan with Air flow max (m3/h): 330 witch have 2 speeds and bottom inline Air flow max (m3/h): 220-280 witch dont have speeds on it so i think i should buy a speed controller for it so i can change the speed what do u think is this gonna be enough to have negative pressure andgood air flow inside ? i also got a clip fan 15 inches to mount inside

OK got it
Wouldn't bother with a controller, you can't draw too much air through there so I'd just leave it on max
If your environment is 30°C+ there's not much you can do about it without AC, but the plants will cope if you have good air flow

so this setup i pick will be good enough for the air flow so my plants will trive the only thing i need to fix in future is the temperature of the room maby with some small AC near the tent will do the job
i still havent order anything wanted to get little bit of assistance if this air flow setup is good i will get it also my budged atm isnt very high thats why i stoped on those products for ventilation will upgrade in future this will be my very first grow in a tent at my room ^^

depending on climate and other factors you may need to vent your exhaust direct to outdoor. recirculating air into and out of the tent within the same room can create a negative loop of environment issues.

the larger the tent the larger the issue. 60 x 60 x 160 is not that large. still something to consider.

my tent is just near a window i can exhaust to outside my room while the intake will draw from the room is that all right?

i don't usually worry about it on smaller set ups like the one you describe, but i'm not sure of your climate. for veg i wouldn't consider it a problem at all in most places.

it may get to be a handful in flower, they transpire a lot more in flower which can be hard to manage.

i run a 3x3 space in veg with no direct exhaust to outdoor. i run a 4x4 flower room and couldn't get away with it without a direct to outdoor exhaust.

this graphic shows the common "proper" set ups for a grow space / tent.

the green line represents an outside wall. the most common and the one i recommend is the one on the left with the exhaust fan and scrubber in the tent. it's the best if you need to be stealth as well.

again, it is far more important in flower than veg.

if you do need to be stealth i would not dump exhaust air indoor at all. the odour will permeate a lot more than you will realize, and can often be noticeable 100's of feet away from the house. a proper scrubber and exhaust are key elements for stealth.

well i think i picked a good fans can u please tell me is this will work

• 

AC Infinity CLOUDLINE T6, Quiet 6 for exhaust its max of 400 CFM can be reduced i think it have alot of speeds​

then for inline to get good fresh air from the room​

​

AC Infinity CLOUDLINE LITE A6, Quiet 6” Inline Duct Fan with Speed Controller, 10 speeds and it have max 350 CFM both have controllers so i will be able to use whatever cfm i want betwin their min/max equipped with AC Infinity Air Carbon Filter 6" so the air from my room witch is not very fresh all the time to be when go inside the tent also i will use duct for the exhaust fan and all the air from the tent will go outside a window witch is 30 cm near the tent​
