How can I vent an attic correctly?

Im setting up an attic grow & Im concerned about the ventilation. Ill be using 6x400W cool-tubes (2 rows blowing out hot air) & 2 inline fans connected to separate carbon filters.
However I dont want to exhaust the hot air out of the roof for the chopper coppers to detect the heat signature (in U.K. they dont need a warrant for FLIR cams). Which is the ideal way to suck in cool air & blow out hot air?

I'm a UK grower.
In my attic there is a hole in the wall. For exhaustion - I simply taped the duct to the hole, thereby venting into the wall cavity.

For ventilation - I simply leave the attic door open. Although, I don't really need to do this as my roof has a very small gap around the edge near the guttering.

Why dont you vent into the home make them look like ac vent's and you are all good with two filters.

That sound like it could work especially the ac style vents but the attic must have cool air coming in from outdoors but in no allowed to cut holes in the roof as their are people living up us. How could I tackle that issue?

you can still bring in fresh air from your home to the attic just as long and intake and exhaust are on opposite sides. So for example you can have you intake on the bottom and the exhausted air will be sucked from the top of the room because of lights but the ducting will end up at the bottom goin into your home.

An Attic should already have decent ventilation. Do you see light coming in up there?

And Exhaust into your chimney, heat is supposed to come out there

Theres no light coming up in the attic & in this apartment there are no chimneys as the law in UK no longer allows gas heaters in these type of apartments, my first choice was to exhaust out the chimney though.

Is your grow room going to be sealed off from the rest of the attic? If so, just vent into the other parts of the attic. The hot air from the lights will mix with the unconditioned attic space air.

I wanted to to use the entire attic but I think thatll be my best bet. Thanks bryant

My attic has a soffet (just below the gutters) that brings in cool air and vents it out via the ridge vent at the apex of the house frame. The "A" does not fully come together at the top and creates a vent. That is the ridge vent.
