Hi there and welcome!
You are getting great advice.
I'm a huge fan of the mailbox mod (mailbox with elbow duct joint, plus into hole in side of MES when you pull out the chip feeding tube).
There is an
A-Maze-N Pellet Smoker (
AMNPS) tray that will burn pellets for up to 12 hours!!!
The MES30 can be hit or miss with using the tray inside the smoker where the tray may not stay lit, BUT has no issues running a tray in the mailbox mod.
Additionally, with a mailbox mod you further reduce the amount of heat that makes it into the smoker from the pellets burning. In Texas the pellet heat is a real thing as we don't get many days cold enough for cold smoking (smoker temp 70F or below) so the mailbox mod helps out some when trying to gold smoke in 40F lows and needing to keep the smoker under 70F. I still have to put a foil tray of ice in the smoker when cold smoking to battle temps increasing but again this is TX not WI so our low temps for cold smoking are much higher than your low temps hahaha.
Finally, I like the mailbox mod because the smoke is fully independent of the heat generation and I never have to open my smoker to fool with the smoke generation.
The tube works inside MES30's and in high altitude/low oxygen environments where the tray may not. Both work where you fill with pellets, light on fire and let flame for 10 min, then blow out fire and the pellets will smolder producing smoke until all smoldered out.
Tube is like 3hrs maybe a little more, Tray is 12 hrs when full.
Almost all of us MES owners switch to a tray or a tube because they are so simple to use and the the tray for sure produces PERFECT Thin Blue Smoke with no fuss.
I hope all this info helps :)
