I am brand new to smoking and recently go a MES 40. I have a quick question regarding the water pan, or when to use or not use it. Does time of year (weather) influence if you add liquid to the water pan or not. I've read one thread where someone mentioned to leave it empty when it's cooler out, but haven't seen a lot of info on it. For reference, I live in TX so cooler to me is below 50-ish. I broke the smoker in with a brisket two weeks ago, and dumped the water pan out halfway through after there wasn't a lot of bark forming. Any input would be greatly appreciated!
