I work with a guy that supposedly is in the military and he told me they frequently help law enforcement conduct flyovers with their special thermal camera to detect grows. I read on another forum those guys in their choppers are mainly looking in the woods for large grow ops. I live in a fairly populated city in new hampshire and am using a 150watt hps should I be worrying? The guy I work with even went as far as saying they can even tell from the sky if its an HPS or not?? He used to grow himself weed and mushrooms. I didnt tell him im growing but was just asking "questions" about it...
