It is my understanding (never smoked myself nor owned any ficus that lived for more than a week) that growing quality plants is actually a very complicated process which takes up a lot of space, requires adequate lighting which in itself is hard to conceil, spacy, as well consuming a lot of power. I doubt suburban kids could be that deep into it.

I mean, just look at what some people are doing in terms of selfbrewed beers and stuff. That is hightech meticulously planned do it yourself machinery and botany.
