As far as security is concerned and keeping them outside how about just making a greenhouse, grow box , or even do what I did on my first experimental grow, use uhaul wardrobe box. I think I paid $11.00 for it. I was in the same boat, started a plant but had no plans beyond that point.
I had cfls, a small carbon filter and 3 foot plant in there. I sprayed the inside with the spray on adhesive and just cut up an emergency blanket to make the walls reflective.
A really inexpensive ghetto setup but you could have that outside and nobody would know what was going on and the smell will be very minimal. Another thing is you can open it up and set it up so the sun gets in during the days without the wind blowing the odor allover the place. Cardboard ignites at somewhere near 800 F so it's safe.
Another option would be make a simple greenhouse from pvc pipe and 6 millimeter plastic from homedepot. It would probably only run $30.00 for materials.
I admire your courage but keep in mind that any growing in FL is a felony, even one plant. It's a big difference compared to a misdemeanor possession charge.
Anyway, keep it going but do make some kind of plan for the smell because it will come out of nowhere and will be noticeable.
