Tent exhaust through window>steam??

Getting ready to switch some things around with my grow. Will be setting up my tent in a second floor spare bedroom. Will be using a 440cfm fan to pull air inside tent through carbon filter, through air cooled 1000w hps light tube and then ideally out the window

One thing I am worried about is that since it’s starting to get cold (not too cold where I live, but 30s or so is normal winter temps from December to February) will exhausting out a window result in a constant massive plume of steam? Luckily the bedroom faces my backyard and I have a semi private backyard with some trees/woods buffering my backyard and the neighborhood behind me, but I am still a little concerned. Does anyone have experience with this? Also was thinking I could just Exhaust back into the room and have a window AC running to keep things cool and dry in the room, but would prefer not too as running the AC is one extra expense.

Air coming out of the grow room won't ever get hot enough to create a steam like vapor out the vent being vented out your window. The air coming out the vent would have to be 100F when the temperature outside is 32F to form a steam like vapor.

I have mine venting out my basement window. In winter there’s no steam, or melting of snow around the window

My vent melts the snow near it but I am moving a lot more air then you would from a tent.

Most high efficiency water heaters and furnaces put out the same "steam"
It isn't noticeable to most people
Life goes on ...let it grow
