You see, because
INSIDE your cabinet is the
Source of the smell. If temporally eliminate the source problem, you have temporary smell relief ... As well all know Marijuana permeates, but because the orange peels are distilled they are naturally stronger than that of the fresh weed. Thus giving temporary relief, I'm talking like a couple of hours.
Now, what you say about about being drawn to a lovely smell in a cupboard for no apparent reason, and open the door? Would you rather have them drawn to the fresh, and obvious smell of cannabis?
Febreeze is more readily available however it is not really cheaper. You get more sprays out of this...
One last point. I don't grow in a cupboard.
