The air temperature in my tent is around thirty with the light down low - the radiator is off in the room but it's a small room and the door has to stay closed to keep the cats out - they'll either rip the tent to shreds, sick up on it or mess it up somehow.

I've decided to have my fan pulling through the cooltube and blowing out a filter in the room. I've used the rest of the ducting to connect the spare inlet on the tent to the window.

But I'm having problems getting decent cold air through it.

We have people living right behind us, so I can't dangle the 6" silver hose out the window. And I can only leave the top (small) window open and the big one on safety (not much airflow) since I don't want anyone trying to climb in only to discover a grow while they rob me.

Are there any smart bits of duct accessory I can stick on the end that'll let me connect the duct to the top window more directly without looking really suspect?
