I think you shouldn't grow without the approval of your mom.
It just isn't fair to her.

If you live in Florida, you're going to have to do something about the heat... ie: air conditioning... probably.
And you're not going to a/c the entire attic, so you can bet on building a cabinet up there.

Smell you can deal with quite easily with a carbon air scrubber.... easier still if you've already built the cabinet.

Soil would definitely be the way for you to go because of simplicity and fuckUp-proofness.

Finally, I don't think you should do it without your mom knowing about it.

Best to you,
