You'd think with modern LED setups this would be null and void. It's quite wild to see a lot of older schooled growers still using sodium lamps and other high heat, high energy lighting fixtures and getting caught, wasting energy, etc.
Now days modern LEDs are multi fold more efficient. You'd also think that if someone was doing bad deeds illegally they'd be more inclined to stick to a more strict standard.
I guess criminals never did have much standards.. Organized crime excluded and even then some organized crime syndicates aren't fully organized in a manner that detection is impossible. They just aren't a nuisance enough to warrant the big league agencies. Local LEOs are definitely picking up new tech and evolving faster as the money rolls in these last 10 years.
