I've got a large deck off the back of my house that would make a nice place to store my seasoned firewood because it provides a good shelter throughout the year.   I could fit 5-6 cords under it.  The problem is that during the summer it is constantly shadey and moist underneath the deck.  Would the shade and moisture factor make it a bad place to store seasoned wood?   Would my good seasoned wood get turned into wet punky wood?
