how far along is the plant? at the point where it needs to be dried?
if so get yourself a rubber maid tub.. how ever big of a tub you think you'll need.. and make sure its a dark colored tub.. id perfer a black or dark green one from wally world..
get some plastic adhering spray paint.. camo colors... if the tub is black, get whatever color spray paint that matches your surroundings.. (if you live near alot of green, youd go with a green, lite green, and another in between) you get the idea.. basically spray the OUTSIDE OF tub to hide it from wondering eyes(CAMO), and also with the coatings of spray paint it will help block the light from rottening your crop..
---- what i did when i needed a tub for my babies, was found a grey rubber maid tub, and sprayed it black, 2-3 coats and it blocked the light from seeing it from the outside completely... works well----
neways back to whats important, go and find a nice hiding place in the woods or wherever, you'll also need some kind of belts or straps to keep the tub closed from being opend by hungry animals..
you will also need some mason jars (yes the kind for canning) these will hold your crop,
the tub holds your jars..
theres also a drying process of course.. but ill get back to you if your looking for more input.. im assuming you got that coverd, just looking for a way to dry it outside...
