I store my pellets outside tarped, on pallets, under a lean to. Just for the heck of it I thought it to be a good idea to check the moisture content of the pellets. Soooo I put a handfull in a bowl, put a loose fitting lid on it, set microwave on HIGH for 5 min. After about 3 min. I smelled smoke coming from the kitchen, and smoke pouring from the microwave. So much for that idea.
