ok I see what's going on here guys. These lights he is using are only 150 watt lights which are "600 watt equivalents." He has 16 lights at 150 watts = 2200watts total. Hell grow in your closet dude. The fixtures are 4 inches wide and 39 inches long. He could line them all up on the ceiling and nobody would notice. LOL Well not exactly but seriously, the only thing you really need to do is make sure that you use C-3 film and that you use proper and I mean proper ventilation into the attic. Use a bedroom or a garage even as the grow space and line it proper with C-3 anti detection film. This will make the room cool to cameras that would look from all 4 sides of the home and above. Line all walls even the ones that are on inside walls. Then cut proper sized holes in the ceiling of your space and vent everything into the attic. Use a scrubber before it goes out of the room and this will keep the smell down. Again, keep in mind your total wattage is around 2200 or maybe 2500 per hour at max, I would think this will easily pass under the radar in terms of electricity usage. 2000 watts is about the equivalent of 2 high end gaming computers running Counter Strike or something. Now a days people use that kind of electricity easy. Think about all those houses with 4 a/c units attached to the wall. Easy 2k watts right there.

Your concerns will be about heat detection which is easily defeated with c-3 film. My statement about distributing still applies and don't tell a soul. Good luck.

By the way, I think you could have likely done the same thing with 2 x 1000 watt HPS lights @ about $300 each. my 2 cents
