I want to buy this smoker But i dont understand wood pellats. Apparently wood chips like i can buy in a bag in grocery store wont go far. I am determined to learn to smoke a brisket properly. Ive mastered smoking whole chickens on A propane grill so i think i can do it. If i but this grill am i signing up for spending money on these pellet things? One cant justbput wood in the right hand side and set it on fire?
