Yes good point.I went threw this a couple years ago myself. I hope you haven't burned all your dry wood so you have some to blend with the wet. I burned a lot more wood in my Garn during that period than normal. I takes a fair amount of BTU's to get that wet wood burned. This year all 15 cord is under a roof in trailers.
I do have a cord or so of dry and mix.
Never had a problem in the past.....just go to the woods and haul back nice dry oak that's been split/stacked for a year or better.
Not this year with record breaking rain.
