So I'm venting out of my chimney. The questions are. . .

Will the heat from a 400hps make steam if it is vented into a cold environment?

will the exhaust cool before it hits the outside?

I don't want my neighbors to see steam venting from a chimney. Also the exhaust has to travel about 30-40 feet to exit the chimney.

do you really think the neighbors are gonna think ur growing weed cuz theres steam coming outta ur chimney?? i find that kinda funny..

It wont steam, even if its a non working chimney, in older houses Heating systems and water heaters usually are vented through the chimney.

I don't think steam from my chimney will mean "pot grown here" but I would like to have no trace. The house is old. It has a basement with a secret room equipt with hidden door. I run my exhaust between the wall into the chimney. The house doesn't have a fireplace. It did but they covered over it. No other pipes go to the chimney. They all are in different places. I used to live two houses down as a kid, and the neighbors (most) know me. I never used to smoke. So I would rather scrub the air and dump it between the floorboards than exhaust steam out of a non-working chimney.

. . .But if you guys say that no steam will be created I will let you know. Thanks

I just have to ask. What is steam coming from? Also, it's normal for thing to come out of a chimney.

shouldnt be a problem but why not vent to the attic?

Just get a good carbon filter and spread the heat throughout the house. This is also very effective against FLIR... FLIR is utilized, by the man, to detect suspicious hot spots. If you spread the heat to every room of the house, it will look like any other house, and not raise any suspicions...

chimney is a great hot spot, it suppose to be, the other good thing out venting through the chimney is you shouldn't need a carbon filter, no noses 35, 40 feet in the air to smell it. I dry in my wood stove and it goes out the top
