Sounds like the kid took some bud to school to hook up a friend, then the friend snitched. So they took the teen, and his phone, got the warrant to flip through the pictures and found the bud shots. So they did some homework and took down the grow houses.
Looks like the dude was running 8 to 10 lamps in the one room. Dunno why someone would run air cooled hoods without any ducting... I mean... Might as well run Parabolics or vertical bulbs in that situation if the AC could handle 10,000 watts of lighting without any ventilation.
He had it going on though. Gotta talk to your kids...
