Everything I read says to use dry wood. I thought mine was dry but it is greener than I thought. I do not have a moisture meter but can tell because it seems heavier than it should. Do you use a moisture meter? If so what model and brand and where did you get it. If I am burning it pretty hot (it is burning great) do I need to worry about creosote making it through the cat or does that usually burn off the creosote?
