So I used my WSM for the first Time this past weekend. I had some issues with temperature control, first went really hot then quickly cool down when I put a bowl of cold water in the cooker. I was cooking in colder weather ( about 30°) and am wondering if that combined with cold water in the bowl made it harder to keep the temperature up. I was worried because I hear that new Weeber smoky mountains run hot. I think this was The case at first, but should have let it run without water as it was so cold. Besides the cold water in the steaming bowl, what else could've made my smoker not go hot enough? The vents were all open by the way.
