Hey I have two smokers one is charcoal and the other is an electric smoker. My charcoal smoker has two vents on the bottom and two on the top. I usually leave both vents open on the bottom and the top ones I leave half cracked or full out open. What should I do for max heat, I struggle to keep it at 225 at times? I feel like 4 vents is an over kill for a small smoker.
