So I want to share something with you guys if it hasnt already been shared or done. I have the AMAZN tube and when I first used the pellets in it, I got smoke output but the thing wouldnt stay lit OR the smoke flavor wasnt strong enough. So after a little trial and error I have found the loading the AMAZN tube with a mixture of wood chips and pellets works EXTREMELY well. I load the bottom 3rd of the tube with wood chips. Use the back of a grate cleaner to push it down and pack it in really well. Then I layer some pellets, then more chips, then more pellets and so on until I get to the top. At the top I use some pellets to get the flame started.
I tried using ALL chips one time and the grill temp was about 25 degrees higher than what I wanted so idk if mixing the pellets in helps with that but it seems like it. The tube lasts anywhere between 3 and 4 hours. Including pics of the smoke output. Edit: pictures uploaded sideways for some reason
