Yeah Muddy is totally right, your friends mum will find out, I grow in an apartment in one of our rooms, we have neighbours on the other side of all the walls except one, I do not use a filter as I grow only one plant but does it smell? Shit yes...and then some! It is a really nice fruity smell I might add but it is very very pungent and unmistakeable as you know. I keep the door to that room closed most of the time so the smell is contained to an extent and it does not stink the apartment out, only that room..... but I am not trying to hide it from my mum. I would never have been able to do this when I was still living at home with the folks. Best to leave it till he gets his own place or rent with some friends, you dont wanna get his parents in trouble with the law...
And wont mum notice the increase in electricity usage? Mine would have....then she would have kicked my arse lol :hot:
