Hi guys, I am new to smoking. Recently purchased a MES at home depot (display model) for $149 w/ remote and glass window. Anyways, I am pre-seasoning the smoker at 275 for 3 hours and just added less than a handful of chips at the last 45 minutes according to the instructions. At 1.5 hours, the temp actually got up to 186 but I closed the vent 75% and the temp went down drastically. I then re-opened the vent again to 100% and it maintained a temperature of 170-172. Everything is heating up but I cannot see any smoke!?!? I am in Washington D.C. and outside temperature is at 39 degrees at night. What am I doing wrong?
