@MindfulWilliam @leturos you could also check facebook market place for saw dust. I found a number of sawmills and workshops that are giving it away, and will sometimes deliver a dumptruck load for a small fee. They want to get rid of it. For now I'm just using hardwood fuel pellets and soy hulls. Its simple and predictable, and until I have my skills leveled up, they provide easy repeatable results.
