dont grow.. hahaha
ummm really, they will be looking for heat coming out of your house... I have seen people vent all of there hot air into their house to evenly distribute the heat, but for the most part, they will see hot spots from your lights if they are not adequately air-cooled, and even then, the hot air has to go somewhere, so they will see wherever your exhaust is.. try and keep everything as cool as possible, and maybe vent your heat to 2 different areas of the house... AC in the room will help keep temps in check (and they are only about 100 bucks at your local home depot), then you vent your heat from your lights elsewhere... other than that, i dont know.. I got a cann card, so they can stop by and seem my babies if they want.. haha
