Tropical storms in FL will require a very strong enclosure. I'm afraid that if citrus isn't that valuable to you, it probably isn't worth the effort.
Then again, if citrus is your jam, then Fort-knox style containment should be possible, having an air handler to keep the pressure inside the enclosure higher than outside, and having a multidoor access point with timing protocols to keep the inside pressure from dropping would be a possible solution.
How much do you like citrus?
