You can't see an outdoor grow with thermal imaging. This guy is full of shit.

Not to mention that it's basically an illegal search if they fly over your home and take thermal images without a warrant. 150W isn't even as hot as most motion lights in people's driveways.

thermal imaging CANNOT see into your home. it can only see heat that radiates out of your home. So unless you're growing in a poorly insulated attic like someone else said, or venting hot air out of your grow room to the outdoors, then you're fine.
