My stove seems to do better with 4x4 pieces even for the all night burns I just damp it down and let the secondaries do the work. If the splits are to big it burns dirt in my stove. I fill her up with the least amount of voids and let her go,always have a bed of some coals left to restart
Oh We Love All Nighters!!! When the “night wood” burns SO Hot and SO Long, you’re sweating up a storm and have to kick the covers on the floor!! How bout that!???? LOL ~Lissa
