I am currently using a brinkmann smoke n grill upright waterpan smoker. What type of fuel should i use? Charcoal briquettes or hardwood lump charcoal? What are the main difference between the two of them? I am very new to smoking and i just want to try to avoid making mistakes. I am currently using briquettes. I didnt even know there was different types of charcoal until just a couples weeks ago. Please help me with whatever advice you have to offer.
