ventilation setup help

I have a hydrohut 3x3 and i have a cooltube and a 6"growbright inline fan and a tallboy carbon filter 6" and my question is would it be best to place the carbon filter outside the tent connected to the fan ducting into the tent connectin to the cooltube and ducting out the tent to let the air out? but my concern is how air coming into the tent ? do i just leave the bottom vents open ? or get another inline fan to blow air in or just get mini fans to mount on the inside ? your help would be great since this is my first time growing.

btw im also using a lumatek 400w digital ballast, 400w mh conversion bulb, and 5 bubble boy DWC , hydrometer / temp in my grow tent hopefully thats a good start for my first grow.

I tried a passive intake in my grow room and it started sucking the plastic off the walls when i kicked on the inline for exaust . like deflating a ballon .

so what setup would be best for a 3x3 tent so that my plants are keep cool and safe and healthy ?

or the carbon filter in the tent ducting into the cooltube and ducting out the tent into the fan and out ?

Hang the filter in the tent and run the ducting to the attic if you can. Hook the ducting to your fan and then ducting to the opposite side of your fan. I bought a little fan and hang it from a bungy cord in the tent. I took a 2 liter and cut both ends off and stuck it in one of the bottom holes and tightened the strings around it. The fan on the inside of the tent pulls the fresh air good. You could get away without a fan though and just keep it passive.

im sorry i dont understand what you mean. hang the filter in the tent and ducting and i cnt put it up to the attic i can out the window is that fine ? but sudnt i attach the inline fan to the filter ? also how do i get air inside ? i was thinking about hanging the filter up and ducting it in to the cooltube and out the tent to the inline fan and out goes the air or sud i instead of using the inline fan like i said just let the air from the carbon filter ducting out to outside the window? and to get air in get a inline duct fan ducting from outside the window to get fresh air in the tent ? would that work good and add like 2 fan mounted in the tent ?
