In my area I'm growing for myself and three others b/c I caregive. I have a very big energy bill and NO ONE from the utility company has questioned me. Keep ur lips sealed and be careful, u tell one person, they will tell two more ppl who tell two more and so on....as far as the smell is concerned a round charcole filter that can atratch to your fan will reduce that funky smell. And plastic the whole perimiter to try nd keep the smell in. My room is air tight with co2 and when the door opens, it wreaks. Just be aware of the little things too. Cars on the block that aren't usually there...nd so on. I called the cops one time on this suspicious looking van one time when ppl were just sitting in it. Lol maybe a little overboard but u can't be too careful.
