Drying outdoors is going to be quite a challenge.
What I would do in that situation (which I will never be in, lol) is go buy a big tarp, one with camo print on it, or if not, an olive green one and spray paint it camo. Make a tall tent, with both ends open and oriented to catch the most breeze, and hang your plants upside down under that to keep rain off.
Your enemy is MOLD and of course being seen.
