Look at the crazy color difference in these two pellets. On the left is HDX from Home Depot. I'm assuming these are Heatrs as I have a few bags of these and they are very dark like this. On the right is beetle kill pine from Ecoflames. Those have been my staple and favorite so far this winter. The Heatrs not so much. It's funny, I used to live a few miles from the Heatr plant in Showlow AZ and burned them exclusively. They were never this color. I'm thinking they're using scorched logs from that huge fire down there in '02. I'm guessing here, but that is the largest stand of Ponderosa pines anywhere, and they're not this color unless they're burnt.
