It's possible, I'd say find the lowest point out in your giant area of woods and set up some card board boxes with green or brown tarp hung above them. String some fishing line inside to hang your buds and maybe cut a big venting hole low on the side. Basically mold is your problem since air exchange is limited but you want them to stay in the dark. I would check them daily to open the boxes or replace them if they get wet.
