Weed smells... no real way around it i guess. Some strains smell alot more than others. I have some strains that were bred for low odor and they still smell somewhat in flower.

In veg they dont smell too bad but im sure thats strain dependant. When you start to flower there is no real way to hide it unless you have something for the odor. Like a carbon scrubber or some ONA or maybe even an ozone generator. If you think you are going to grow even 1 plant without anyone smelling it WITHOUT buying something to address the odor then you will be dissapointed (and possibly busted).

What about a closet? or a spare dresser that you can convert into a cab? Lots of better places than a washing machine... You can even build your own cab. Theres lots of DIY threads around here. An easy one is using two big rubbermaid tubs!

Good luck with your grow and make sure you do an insane amount of reading before you try otherwise you will probably be bummed with your outcome.
