Ok, I'm new to the whole electric smoker world so please excuse my lack of knowledge. I am eager to learn. I picked up a Gen 1 MES 30 part # 20071814 for Ace hardware on special. It looked like a great way to enter this learning process. I completely understand that it is a PITA to add wood chips every 30 minutes to an hour. I've seen several posts about the A-maze-N pellet smoker (APS), the Masterbuilt Cold Smoker(MCs), and the "mailbox" mods. I also understand that the MCS generates heat so it makes sense to place that further away on a cold smoke. I guess what I am confused the most about is why do the mailbox mod if the APS fits in the MES? Does the APS have to be outside the MES for a cold smoke? Does it generate that much heat smoldering? It just seems to me that the least complicated solution is to just place a APS inside the MES. Can someone elaborate on the pros and cons to each set up and why they are done? The biggest reason I got the MES is to do cold/low temp smoking for salmon, cheese and jerky. My other "smoker/cooker" runs in the 275 degree range and won't go low enough for these items. Thanks in advance!
