Well, it all depends. We had like 6 photos going in the back yard this year, right in amongst a bunch of townhouses and units. Some of them were 5-6 foot tall and yielded 300g each, and the smell wasn't too bad. Noone even noticed at my house, but on the other hand I've had mates grow a single auto in there cupboard and the whole house stinks.
It seems to pick and choose when it smells.
These photos (there were 3 this size) were basically undetectable smell wise, but my roommates single plant in the garage stunk the house out.
