Not necessarily. Don’t get so caught up in 220 or 225 for your smoker temp. You can cook at a higher temp and still get excellent results.
You’ll have more fun if you aim for a temp range. Say 240-270. As long as you are in the range just watch the smoke roll and enjoy.
I'll second this advice. One of the learning experiences I had along the way is that it's easy to get caught up by the whole 225 degree temperature that's listed everywhere, and I did too when I started out. What I discovered was that for a given barbecue burning a given charcoal, with a reasonable vent opening that's not at an extreme end of the range so you have room to adjust more open or more closed, all in the particular environment it's in, there'll be a window or a range of temperatures it'll settle in and run at easily.
What I've found with my WSM with Weber briquettes or Royal Oak lump charcoal with the vents partway open is that it settles in and runs around 250 degrees. Getting it to run hotter than that can be done but the vents have to be wide open and it'll only go so high before it tops out. It eventually got up to 290 degrees for the last 25-30% of a hot and fast cook I did on it tonight with a prime rib roast but it was almost completely opened up to pick up the extra 40 degrees. Getting it down to 225 and having it stay at 255 without creeping back up or snuffing out the fire from shutting all the vents down too far has always been nightmare of watching it like a hawk and constantly adjusting the vents with that thing. Ever since I found it settles in and runs at 250 on its own once it's set up, I've been enjoying far better food with far less effort.
I guess what I'm saying is for your particular barbecue with the charcoal that you happen to use with your local climate that it's working in, there'll be a naturally occurring operating point, a sweet spot, that it'll settle into for long low and slow smoking. It might or might not be 220 or 225 degrees, but the important thing is to find out what is is and then let it run there when you're doing long smokes and it'll be much easier to let it run where it runs best and easiest.
