Per Serapis' advice, Go watch some FLIR / YouTube.. I did.
About 3 hrs worth.
Kept looking for answers to different ideas.
People in FLIR do not seem to have their breath (+90 deg) showing, neither do the dogs.
Didn't notice any window style AC outputs on homes.
Didn't see any indications of sewage drain vents on smaller homes. (Generally easily felt if on the roof)
Also watched a series compiled by a reformed(?) cop / DEA that trained dogs.
Thanks Serapis for steering me there.
Have a buddy with a card that say's he's golden. (But way over the legal to do card limit!
) In a 8X10 room he's running 4 - 1Ks, inside room, it feels like 100 Deg. and humid in there (plants not looking good, but anyways) I'll bet you his grow shows like some in the vidios?
However, for my little personal (under card limit) with a 250 vented inside grow area, mixed, and expelled at 5-10 deg above ambient. Then travelling 10 ft. to the cellar and another (in the cool cellar) 15 ft to the chimney and out I honestly don't think would show very well. I may be kicking 5 deg at most on the chimney top? I'm thinking it would probably exhaust cooler than room temp? (Sometimes it's nice being small).
Anyone disagree with that?
If my train of thoughts are wrong I'd rather find out from you guys before the knock on the door. - Thanks.
