Hello all. I'm concerned about the storage of my leftover tons of pellets for next year's season. They are stored in a separate narrow room under my porch that is accessible from the basement. The temp stays around 55 being in ground, but the humidity is around 50% presently. I'm not sure if that changes much. The bags are stacked to the ceiling - ~ 1 1/2 tons per pallet. Should I be concerned that the humidity will affect them for next year?
