I bought 10 bags of these from Southern Maine Renewable Fuels. The pellets are a mixture of soft and hardwood. They burned very hot and average ash. The glass didn't really get dirty at all. There were fines in the bottom,but very little. I actually enjoyed the smell of the pellets too.The bags are a green and brown color and are sturdy enough. I believe these pellets are going for around $260 a ton. I really enjoyed these pellets and would/will burn more in the near future.
