I built an overhang off an existing outdoor shed to store my pellets. Made it big enough for 4 ton. Has no floor, but does have roof and walls. I want to empty some of the bags in a large plastic rubbermaid garbage can and leave in the house, so I don't have to keep toting in bags everyday. Someone told me that if the bags are open they get moisture. Will it be alright to dump open bags in this garbage can and store them in the house with the top on?
